Trees talk to each other and recognize their offspring mycelia (the main body of fungi, as opposed to the more well-known fruiting bodies - mushrooms) acting as a sort of old-school planetary internet is still a fairly recent one, and may serve as a spore of a new breed of forestry, ecology, land management.
the lure of reductionist thinking, with a tree being considered merely a commodity in the forest, which can be replaced simply by planting another tree. In fact, many reforestation efforts are considered successful when a large number of trees are replanted in areas where clearcutting has rendered large tracts of land treeless, even if those replanted trees are essentially turning a once diverse forest into a monocropped 'farm' of trees.. As Simard, who has put in about three decades of research work into Canada's forests, puts it, "A forest is much more than what you see."

could Douglas fir recognize its own kin, like mama grizzly and her cub? So we set about an experiment, and we grew mother trees with kin and stranger's seedlings. And it turns out they do recognize their kin. Mother trees colonize their kin with bigger mycorrhizal networks. They send them more carbon below ground. They even reduce their own root competition to make elbow room for their kids. When mother trees are injured or dying, they also send messages of wisdom on to the next generation of seedlings.

Trees in the forest are social beings From counting and learning to communicating and caring for each other, the secret lives of trees are wildly deep and complex.
"They can count, learn and remember; nurse sick neighbors; warn each other of danger by sending electrical signals across a fungal network known as the 'Wood Wide Web' – and, for reasons unknown, keep the ancient stumps of long-felled companions alive for centuries by feeding them a sugar solution through their roots."
These are just a few of the secrets that Peter Wohlleben, a German forest ranger and best-selling author, has learned about trees.
Upon coming across a duo of soaring beeches in the forest, Wohlleben, the author of the runaway hit book “The Hidden Life of Trees: What They Feel, How They Communicate – Discoveries From a Secret World,” observes:
“These trees are friends. You see how the thick branches point away from each other? That’s so they don’t block their buddy’s light.”
“Sometimes," he adds, "pairs like this are so interconnected at the roots that when one tree dies, the other one dies, too.”
For someone (me) who has can’t help but to anthropomorphize trees, these words ring deep and true. And Wohlleben’s work could be changing the way we think about trees.
Photo: Giant sequoias put things in perspective Few things can make us wee little humans feels as small as gazing at a giant sequoia (Sequoiadendron giganteum), seriously! Consider this, the giant sequoia known as General Sherman tree – the largest, by volume, known living single stem tree in the world – reaches a height of 275 feet, diameter of 25 feet and estimated bole volume of 52,513 cubic feet. And its 2,300–2,700 years old! The Parker Group of giant sequoias, shown here in a photograph by Rick Derevan, lives in the same place as the General – Sequoia National Park in California – and is one of the finest clusters of the big guys in the park. Respect!
1/4/17 email from Treehugger:Guujaaw, a former leader of the Haida people, wrote about the ritual before cutting down a tree: "The man embraced the tree, honouring the life that was to be taken; for he knew each tree, each plant, each animal, is a living spirit, like ourselves."
Sustainable forestry is about more than just trees: it's also about culture, history and politics Before one can even begin to discuss sustainable forestry on Haida Gwaii, the islands off the coast of British Columbia that used to be called the Queen Charlotte Islands, one has to discuss the extraordinary history of the Haida themselves, their relationship with the islands and with the trees. I visited the islands recently as a guest of The Rainforest Alliance, to see their sustainable forestry operations, learned that the story of the Haida and their forestry is far more interesting and complicated than I realized.

Around 1850 there were thirty thousand Haida living on the islands, and they were among the richest and most successful peoples on the West Coast. They lived on fish and the products of the forest, worked iron recovered from shipwrecks and travelled up and down the coast in their giant canoes. They developed a rich cultural life and great art, the most famous being their carved poles. The poles were carved from the giant cedar trees, which also provided bark that was woven into fabrics.
The Haida don’t look at trees, plants or animals as simply things to harvest, or think of themselves as something different- they are all part of the land. One of their leaders, now known as Guujaaw, wrote:
In the olden days, the cedar tree was carefully chosen for use. The man embraced the tree, honouring the life that was to be taken; for he knew each tree, each plant, each animal, is a living spirit, like ourselves.
In 1863 an English ship dumped a sailor sick with smallpox on the island. It and other diseases like tuberculosis spread through the Haida and killed almost all of them; a 1913 census found exactly 597 of them left.

The Haida set up their own forestry company, TAAN Forest, and ended up controlling more than half of the lumber rights on the newly renamed Haida Gwaii, or land of the people.
Every tree is a splinter of Haida culture embodying not only their ancient history and lifestyle, but the more recent struggles to stop massive clearcutting, create forest reserves and parks, regain control of the islands, achieve recognition as a people and a surprising degree of political control and independence.
It is clear that trees on Haida Gwaii are much more than just lumber to chop down and sell; they are part of the people's lives. As Guujaaw noted, without them, they are not Haida.
Trees form friendships and remember their experiences [Peter] Wohlleben is a German forester and the best-selling author of The Hidden Life of Trees. He has spent decades working with our arboreal cohabitants and getting to know their secrets.
It may come as little surprise that we've written about the tree-whispering Wohlleben before. First there was Trees in the forest are social beings, followed by Trees can form bonds like an old couple and look after each – and thus it appears that whenever I read another interview with Wohlleben, I can’t help but to write again. The following comes from an exchange with Richard Schiffman at Yale e360. The whole interview is poetry (hey, poetree!) but I especially love when he talks about trees and memory:
We had a heavy drought here. In subsequent years, the trees that had suffered through the drought consumed less water in the spring so that they had more available for the summer months. Trees make decisions. They can decide things. We can also say that a tree can learn, and it can remember a drought its whole life and act on that memory by being more cautious of its water usage.
In the meantime, don't forget to hug a tree. It may even remember that you are a friend.
5 reasons not to underestimate the power of plants and trees These scientists say that respecting and understanding plants and trees is essential for our future.
This is what the BBC World Service Inquiry program wondered when they asked four scientists what they thought about plants. Here’s the takeaway:
1. Plants could be cognitive and intelligent
Professor Stefano Mancuso runs the International Laboratory for Plant Neurobiology at the University of Florence. In an experiment with two climbing plants, they found that both competed for a single support when it was placed between them. The plant that didn’t make it to the pole first immediately “sensed” the other plant had succeeded and started to find an alternative. “This was astonishing and it demonstrates the plants were aware of their physical environment and the behavior of the other plant. In animals we call this consciousness. We are convinced that plants are cognitive and intelligent.”
2. They're all brain; and we're dependent on them
Mancuso continues, "Plants distribute all along the body the functions that in animals are concentrated in single organs. Whereas in animals almost the only cells producing electrical signals are in the brain, the plant is a kind of distributed brain in which almost every cell is able to produce them." Underestimating plants can be very dangerous, he says, "because our life depends on plants and our actions are destroying their environments."
3. They could be sentient beings
Professor of forest ecology in the department of forest and conservation sciences at the University of British Columbia, Suzanne Simard talks about the ways in which trees are linked together underground. She has studied this "wood wide web" and says that trees communicate with each other and then behave in certain ways.
"We grew Douglas fir in a neighborhood of strangers and its own kin and found that they can recognise their own kin and we also grew Douglas fir and ponderosa pine together. We injured the Douglas fir by pulling its needles off [aww], and by attacking it with western spruce bud worm [ouch], and it then sent a lot of carbon in its network into the neighboring ponderosa pine. My interpretation was the Douglas fir knew it was dying and wanted to pass its legacy of carbon on to its neighbor, because that would be beneficial for the associated fungi and the community.”
Simard says that we should shift our thinking and change our attitude which would be beneficial for our forests. "We haven't treated them with respect that they are sentient beings.”
4. They can help us better understand nature to advance our future
Dr. Barbara Mazzolai is the coordinator at the Centre for Micro-BioRobotics at the Italian Institute of Technology. She uses plants as a biomimetic starting point to design robots. So smart.
She says they can use a plant-inspired robot for environmental monitoring, space applications or rescue under debris, "because it can adapt to the environment like a natural system. The robot doesn't have a predefined structure, but can create on the basis of need."
"Medical robotics could also be a key application," she adds. "We could develop new endoscopes that are soft and able to grow inside living human tissues without damage. Plants are underestimated. They move under the soil and it's difficult to understand the behavior of these systems. But they have features that can really help us understand nature."
5. Their ability to adapt is crucial for us to learn from
"There's information being exchanged between roots and leaves and flowers and pollinators and the environment all the time. The plant is making 'decisions' – should I change 10 degrees to the left, five degrees to the right? Is it time to flower now? Is enough water available?”
Chamovitz says that in our modern environment – with its global warming, changes in precipitation, and shifting populations – we need to learn from plants about how they respond to their environment and then adapt.
"We've completely underestimated plants. We look at them as inanimate objects, completely unaware of the amazing, complex biology that allows that plant to survive."
If we don’t learn from them, he says, “we might find ourselves in a big problem 50 to 100 years from now.”

Video: Half of Earth's Trees Are Gone and Humans Are to Blame New study from space shows there are 3.04 trillion trees on earth. 422 trees for every human on the planet. Humans are responsible for 15.3 billion trees per year--two and a half times the number of people on the planet. From the beginning of human civilization, we are responsible for the loss of 45% of the earth's trees. Trees provide us with oxygen, trees cool our environment and help to deflect the island heat effect, they sequester carbon, and they purify the air by capturing air pollutents.

Plant a Billion Trees Forests Help Sustain All Life on Earth; Forests Produce Clean Water; Forests Naturally Filter Air; Forests Regulate the Global Climate; Forests Support People and Nature
Forests are complex ecosystems in which plants and animals coexist with one another. Trees are the dominant species in forest ecosystems and are important to maintaining a healthy planet. As the Earth’s great air conditioners, trees rid the air of excess carbon dioxide and other pollutants to improve air quality. Their shade cools the air in summer, and they also filter water, trap particles to make soil and help regulate climate patterns around the world. It is important to understand that in both rural and urban areas, trees provide valuable services that have a direct impact on our lives.
"In one day, one large tree can lift up to 100 gallons of H20 and discharge it into the air" --American Forests.
Pine trees have a long history of healing, so I try to partake as often as possible. Therefore, my first real outing since my surgery was to attend the Longleaf 101 Academy in Jasper where for three days the Longleaf Alliance out of Alabama trained us, toured us, and tested us. I do love seeing what rare glimpses we have left of these once majestic longleaf pine forests. Texas once boasted 3 million acres of virgin longleaf pine forests but sadly all were cut for timber early in the 20th century. Thankfully, a passionate group of brave souls is promoting the regeneration of and planting new seedlings for the future. Any sites that William Bartram described in 1791 as “vast forests of the mostly pine trees that can be imagined” certainly deserve our preservation and restoration. With only 3 million acres of the original 90 million that existed in the South, the longleaf pine ecosystem is considered one of the most threatened in North America. The almost unbroken stand of longleaf that stretched from Texas to the East Coast was the largest ecosystem dominated by a single species on the continent. I can’t help but think of the now extinct Passenger pigeon which was once considered the most populous bird on the continent.
Posted to Davey Facebook page 2/13/16:
I would never use Davey Tree again. They planted a Montezuma Cypress for me, and they did everything wrong. They told me to plant at the wrong time, they purchased a root bound tree [girdled roots] and then they planted it too deeply. Much of this was admitted to me by one of their "experts."
They also knew nothing about mycelium, which was why I went to them in the first place. The extension agent said they knew all about it.
I would not recommend them to anyone.
Ranges of trees and mycorrhizal status Most mycorrhizal root infections operate as a mutualism, with the plant providing the fungus with energy for respiration in return for minerals and resources that would be otherwise more difficult to access in soil. The relationships between a plant and its mycorrhizae can significantly affect the growth, survival, and fitness of the plant. In the set of tree species for the FOR305 ID Test, there are two functionally distinct types of mycorrhizae—vesicular-arbuscular mycorrhizae (VAM), which penetrate the root’s cell wall and Ectomycorrhizae (ECM), which do not.
The two mycorrhizal types examined in this paper are defined structurally. Vesicular-Arbuscular Mycorrhizae are formed by glomeromycetous fungi. VAM create arbuscles – branched exchange structures – inside the root, notably penetrating the walls of interior root cells (Bagyaraj, 1991; Wang et. al., 2006). Ectomycorrhizae are formed by basidiomycetous and ascomycetous fungi, and create exchange structures known as Hartig nets between cortical root cells. Hartig nets do not penetrate cell walls (Mukerji et. al. 1991). ECM are generally exclusive to perennials, a relationship attributed to the success of perennials in low nutrient, disturbed, and stressful habitats
Mycorrhizae can benefit plants in a range of ways.In general, mycorrhizae have the ability to gain resources that plants cannot adequately access. Because they have a smaller diameter than that of root hairs, fungal hyphae are better able to colonize pores in the soil (Allen, 1991). As noted by Eissenstat, a smaller diameter means a higher length:root mass ratio, which is generally beneficial, as root uptake is primarily correlated with length rather than mass (1992). Benefits are not always constant over the life of the plant. For some species, mycorrhizal infections have a negligible effect, except in times of resource stress, most often drought (Allen, 1991). In these cases, the mycorrhizae are not a continual mutualistic partner, but an “insurance policy.” Mycorrhizae can also be important during early development, giving seedlings a readily accessible network of resources (Allen, 1991). This is especially true if the surrounding plants are closely related, as networks of mycorrhizae between hosts have been shown to allow nutrients to transfer in any direction, and in a way which prefers hosts which are most genetically similar to other hosts in the network (Dighton, 2003).
Over evolutionary history, mycorrhizal status of a species converts from VAM-associated to more “advanced” statuses, such as ECM-associated, on many independent occasions (Wang et. al., 2006). Wang describes the strategy of ECM association as short-term, an opportunistic response to more strenuous environmental conditions, which explains why there are many independent conversions to ECM association, and yet VAM association is still dominant.
Since the ancestor to VAM is thought to have been a key innovation which allowed the evolution of land plants, this would suggest that more primitive groups of species would be more dependent on VAM assocations. Any other species group that showed similarly primitive traits, specifically root hairs that are coarse and sparse, is likely to have a strong VAM association to help improve nutrient intake (Bagyaraj, 1991). This is supported by the findings of Smith and Read (2008), who showed that VAM roots were often more efficient in nutrient acquisition per unit length than non-infected roots.
Chalot and Plassard (2012) noted that VAM play a major role in increasing nutrient uptake, especially for phosphorus, but have limited capacity to release nitrogen or phosphorus from inorganic forms. Conversely, ECM can actively take up inorganic nutrients and provide them to the host. From this, it can be seen that VAM and ECM provide nutrients to their hosts in functionally different ways.
The most prominent orders that were found to be obligate to Ectomycorrhizae were the Pinales and Fagales (Table 2). This is consistent with the findings of Wang et. al. (2005), who showed that Pinaceae and Fagales were dominantly ECM obligate. From analyzing the numerous instances when ECM associations evolved, Wang et. al. hypothesize that the majority of ECM hosts typically grow in nutrient-poor environments, and descend from clades that used to live in less stressful environments; for example, Rosids such as the Malvales. Ectomycorrhizae are known to sometimes have associations with nitrogen-fixing bacteria, which would help in the colonization of areas with resource limitations (Trappe, 1987).
Ectomycorrhizae are more active in nutrient intake. They are also known to secrete enzymes to break down the litter layer in order to gain better access to nutrients (Chalot and Plassard, 2012). Furthermore, while VAM are known to branch into a fan-shaped pattern, the outer extent of ECM, the mycelium, forms a net-shaped structure, which allows for better substrate colonization (Allen, 1991).
The mycorrhizal status of the species examined was dominantly obligative, with associations with Vesicular-Arbuscular Mycorrhizae being common, associations with Ectomycorrhizae being secondary, prevalent especially in species that range in nutrient limited conditions, and with a small group of species that displayed flexible associations.
The defining characteristic of trees is the extensive production of woody tissue, an undertaking which requires good access to nutrients. It is not surprising then that most trees have mycorrhizal associations, as these mutualisms tend to improve nutrient access. The most influential factor for determining VAM versus ECM status seems to be environmental stress, a hypothesis which is supported by the many parallel occurrences of ECM status corresponding to nutrient stress found by Wang et. al. (2006). From the ranges analyzed in this paper and current knowledge of the differences between VAM and ECM fungi, it seems that resource trade-offs play an important role in determining the success of both types of associations. Therefore, through various mechanisms, environment is the main factor which determines mycorrhizal status in trees.

MC Blog How much and how often do you water your MC trees? It may take a couple years to establish them in that size so you probably would have to water deeply every week till the heat breaks. Did you provide mulch for them as well? If not, please mulch around them within 5 feet diameter. Spread compost on the ground thinly then use 3-4 inches layer of aged hardwood or cedar mulch... My weeping MC from Madrone is doing quite well. I paid $13 for a (I believe) 2.5 gal tree - maybe 1 gal. It was just a little smaller than the NMMC I acquired from an unnamed source. The NMMC, btw, is growing extremely well, also. When my battery charges back up, I'll post a picture of that one, too. The leaf structure between these two trees is very different. The NNMC has larger leaves (longer and broader). It also kept its old leaves until, well, NOW. I can still find some leaves from last year (red/brown). It has grown at least 18" this year already... I agree my 'weeping' form doesn't 'weep' like the BC weeping variety. Mature ones are shaped much like a live oak - very round. I've left most of the 'shrubby' limbs on it to help it build mass. I trimmed up about 18" last winter just to mow under it, but you can see it doesn't like being 'nekkid'. It just grew that 'fuzz'... MCs tend to look different from each other much like bald cypress. Short and wide, tall and skinny, etc, you get the idea. Some are just weepy. Some are just upright. Sometimes, it's just better to go with named cultivar if you're looking for specific growth habit. 'Sentindo' is a weepy type. Nanjing beauty is more of columnar type with upright branches. I have this one and so far, I like it... There does seem to be considerable variation in the M.C.s. The ones we bought from Madrone Nursery and at a plant sale at the Heard Natural Science Museum several years ago have a more weeping, bush-like habitus, not like the ones I got from Creech and the one on Wilson Street. They all seem, once established, amazingly tough.
Taxodium mucronatum a huge tree in its native habitat and is pyramidal when young with a dense crown but, like Baldcypress, eventually develops into a broad-topped, spreading, open specimen when mature with pendulous branches (Fig. 1). Capable of reaching 100 to 150 feet in height, most landscape specimens will reach this height. The pale green, needle-like leaves are only deciduous in the colder sections of its range, remaining evergreen elsewhere. The trunk grows unusually thick toward the base, even on young trees... Its delicate, feathery foliage affords light, dappled shade, and the heartwood of Montezuma Baldcypress is quite strong and resistant to rot... Roots: surface roots are usually not a problem... The roots probably will not lift sidewalks and curbs as readily as some
Fruit shape: oval; round
Flower characteristics: inconspicuous and not showy; spring flowering

NANJING BEAUTY is a conical, deciduous to semi-evergreen conifer with needle-like leaves. It is a hybrid cross of Taxodium distichum (bald cypress) and Taxodium mucronatum (Montezuma cypress). This cross was made in China in the late 1970s to early 1980s by Dr. Chen Yong Hui of the Nanjing Botanical Garden. NANJING BEAUTY is noted for its rapid growth rate, ease of rooting, high alkalinity resistance, good fall foliage retention and absence of knees.
Cypress Trees of Central Texas by Keith Brown, April 27, 2011. Cypress trees are my personal favorite group of conifers. The five cypress trees I’ll discuss here are very different in appearance. I see a lot of amateur gardeners try to identify conifers based on leaf type, but this doesn’t work. It’s the seeds that give them away. There are two genera of the cypress family that do well in central Texas that I’ll be discussing in this article: Cupressus (Arizona, Italian and Leyland) and Taxodium (Bald and Montezuma). The two groups have very different foliage. Cupressus have scale like foliage much like most junipers and Taxodium have oppositely arranged needles along branchlets.
The montezuma cypress is nearly identical to the bald cypress in appearance. There are a few main differences:
The Montezuma cypress might be a better tree to plant in an urban landscape than the bald cypress. Although I hate to recommend a non-native over a native tree, the better growth rate and reduced likelihood for knees are significant considerations in most landscapes.
MC: Brazos Master Gardeners While taxonomists disagree on its classification, this wonderful tree is closely related to T. distichum (bald cypress) and shares most of its outstanding characteristics, yet is distinct. Plant habit Medium to tall tree with an open, spreading habit (Bald cypress is upright and dense)
Growth rate: Slow to fast, depending on water availability and soil fertility, Extremely long lived
Adaptable to a wide range of soil conditions. Sheds foliage quickly when temperatures drop to 25 degrees Fahrenheit. Yellow fall color is insignificant.
From seed; direct sow outdoors in fall
Allow pods to dry on plant; break open to collect seeds
MC: Federal Database grows naturally in same environments as mesquite (Prosopis glandulosa).
Rehabilitation: Montezuma baldcypress is being planted along the banks of the Rio Grande in an effort to restore natural ecosystems on sites that were cleared for agriculture.
Other Uses: Montezuma baldcypress is planted as an ornamental [4,12]. It is an important medicinal plant and may have been considered sacred by some Mexican civilizations. A gummy resin produced after the tree is wounded was used to cure skin diseases, wounds, ulcers, gout, and toothaches by the Aztecs; some of these uses continue in popular practice. Pitch produced by burning woodchips in a reducing atmosphere was used as a cure for bronchitis. The leaves were used as a relaxant and a cure for itching. The bark was used as a diuretic and an emmanagogue (an agent promoting menstruation)
Seedlings are subject to herbivory by rodents; greenhouses have to be rodent-proofed. Rabbits will gnaw the bark of outplanted seedlings and saplings
No vegetative reproduction has been reported for Montzuma baldcypress
A Visit to Brownsville’s Secret Montezuma Cypress Grove In March the Lower Rio Grande Valley Sierra Club visited the largest remaining grove of Montezuma cypress trees (Taxodium mucronatum) in South Texas. These majestic trees are growing along the banks of a Brownsville, Texas resaca, an oxbow lake that was once a channel of the ancient Rio Grande. Enormous Montezuma cypresses once lined the banks of the river and all of the resacas that snake throughout Brownsville, but the wood was highly prized for its water resistance, and the trees were cut and used to build the wharves for early Brownsville’s port.
There are only a few large trees left along the Rio Grande watershed, and the Brownsville site is one of only 2 actual groves remaining. The cypress’s seeds need to float in water for a time in order to germinate, so the end of ancient natural flood cycles in the highly engineered watershed, along with the mowing of stream and resacabanks, has kept them from making a natural comeback.
The Rio Grande Valley is the northernmost range of the Montezuma cypress, which is the national tree of Mexico. The Aztecs called it ahuehuete, old man of the water, and once upon a time, when wetlands and resacas were plentiful around river systems, these “old men” grew to enormous sizes. They are, after all, in the same family as giant sequoias and redwoods. The “Tule Tree” in Oaxaca, Mexico is a Montezuma Cypress that has the stoutest trunk of any tree in the world. (It takes 17 people with arms outstretched to span its circumference!)
The City of Brownsville owns about half of the resaca and, thanks to the efforts of community activists, has recently agreed to protect it. Efforts are ongoing to secure the remaining portion of this amazing vestige of the ancient freeflowing Rio Grande.
Sapling Days began more than 10 years ago as a way to dispel the popular notion that trees should be planted in the late spring along with the tomatoes, peppers and marigolds. In fact, in Texas and the Southwest the very best time to plant trees is in autumn and early winter. Trees planted in fall and winter have more time to grow a strong root system that will allow the tree to obtain water during the hot, hot summers in our region.

Where to Find a Real Mexican Sycamore in Austin discusses leaf differences
Quercus muehlenbergii, the chinkapin oak (or chinquapin oak) Chinkapin oak is generally found on well-drained upland soils derived from limestone or where limestone outcrops occur... Chinkapin oak is classed as intolerant of shade. It withstands moderate shading when young but becomes more intolerant of shade with age. It is regarded as a climax species on dry, drought prone soils, especially those of limestone origin...
The chinquapin oak is especially known for its sweet and palatable acorns. Indeed, the nuts contained inside of the thin shell are among the sweetest of any oak, with an excellent taste even when eaten raw, providing an excellent source of food for both wildlife and people. The acorns are eaten by squirrels, mice, voles, chipmunks, deer, turkey, and other birds.
Oak wilt (Ceratocystis fagacearum), a vascular disease, attacks Chinkapin oak and usually kills the tree within two to four years. Other diseases that attack Chinkapin oak include the cankers Strumella coryneoidea and Nectria galligena, shoestring root rot (Armillarea mellea), anthracnose (Gnomonia veneta), and leaf blister (Taphrina spp.).
The most serious defoliating insects that attack Chinkapin oak are the gypsy moth (Lymantria dispar), the orangestriped oakworm (Anisota senatoria), and the variable oakleaf caterpillar (Heterocampa manteo). Insects that bore into the bole and seriously degrade the products cut from infested trees include the carpenterworm (Prionoyxstus robiniae), little carpenterworm (P. macmurtrei), white oak borer (Goes tigrinus), Columbian timber beetle (Corthylus columbianus), oak timberworm (Arrhenodes minutus), and twolined chestnut borer (Agrilus bilineatus). The acorn weevils (Curculio spp.), larvae of moths (Valentinia glandulella and Melissopus latiferreanus), and gall forming cynipids (Callirhytis spp.) feed on the acorns.

Legacy Trees for Central Texas : The Gift That Keeps On Shading There are two oak wilt-resistant varieties of Oak that are proven “legacy” trees for Austin. These are the Chinkapin Oak (Quercus muhlenbergii) and the Bur Oak (Quercus macrocarpa)...The Chinkapin Oak is well adapted throughout our region and can grow in either the clay soils common east of the hills, or in the caliche soils of the Hill Country (where it grows naturally in sheltered canyons). When it is young, the Chinkapin tends to have a symmetrical upright form. When it matures, it gets middle-aged spread, shading a wide area with its large handsome leaves. I tend to use a lot of superlatives when I talk about Chinkapins.
Bur Oak – Could it be our best fast-growing shade tree? While some introduced trees, such as Sweetgum and Magnolia, may struggle with our alkaline soil and our slightly basic water, the Bur Oak is adaptive and quite at home... Weather extremes are of little concern. After a two or three year establishment period, supplemental watering is appreciated, but rarely necessary. The Bur Oak comes out the other end of drought with some brown margined leaves and a few less acorns—but mostly unaffected... It is our good fortune the Bur Oak has so few insect and disease concerns. Even Oak Wilt bypasses the Bur Oak...
Bur Oak Quercus macrocarpa is a large deciduous tree growing up to 30 m (100 ft), rarely 40 m (130 ft), in height, and is one of the most massive oaks with a trunk diameter of up to 3 m (10 ft); reports of taller trees occur, but have not been verified. It is one of the slowest-growing oaks, with a growth rate of 30 cm (1 ft) per year when young. A 20-year-old tree will be about 6 m (20 ft) tall. It commonly lives to be 200 to 300 years old, and may live up to 400 years... The acorns are very large, 2–5 cm (0.8–2 in) long... Bur Oak is sometimes confused with Overcup oak and White oak, both of which it occasionally hybridizes with.
Legacy Trees for Central Texas : The Gift That Keeps On Shading There are two oak wilt-resistant varieties of Oak that are proven “legacy” trees for Austin. These are the Chinkapin Oak (Quercus muhlenbergii) and the Bur Oak (Quercus macrocarpa). Both of these are large deciduous trees with a moderate rate of growth... The Bur Oak is the classic Oak of the prairies. In Central Texas it is best adapted to the deeper clay soils east of the Balcones Escarpment. My neighborhood (adjacent to Shoal Creek) has several magnificent specimens of this tree. The leaves of the Bur Oak are often called “fiddle” shaped because of their deep rounded indentations, the name “Bur” refers to their fringed acorns, which can be as large as a golf ball. If you have the room, and want a healthy, stout, giant of a tree, then plant a Bur Oak.
The Bur Oak (Quercus macrocarpa) They are quick to bring up all of the common issues associated with oaks (in general). We’ve all heard them. Oaks are slow growing. Their roots grow on top of the soil and damage your slab or your sidewalks. They get oak wilt. While each of those statements are true in some measure in certain oak species, none of them apply to the bur oak... The bur oak is one of the fastest growing and the largest of all of the oaks in Texas. With normal water, you can expect the tree to grow a minimum of one foot per year. With ample water and a little fertilizer it is not uncommon to get two or three feet of growth per year out of your bur oak. .. Because it is native, the bur oak also takes the extremes of our climate in stride. The drought of 2011 killed many, many live oaks. The live oaks died because they have a shallow root system that grows right at the soil line (and breaks slabs and sidewalks). The bur oak survived the worst drought in our history because it develops a deep tap root that can find the underground moisture needed to sustain it when the rains fail us. This deep rooting structure not only keeps it alive in low water situations but also makes it a great choice for the landscape. Deep roots do not break slab and sidewalks... As much as I love this tree, it does have one little problem – it produces golf ball sized acorns. I have to admit, that since the acorns are large enough to interfere with mowing or heavy enough to ding a new car, you should think long and hard about where you plant it. The good news is, it doesn’t produce a ton of acorns. And, since they don’t fall but once a year in autumn, they can be managed by setting your mower a little higher or picking them up (they look great in a bowl on a table) before you mow. Besides, since the squirrels and the deer love them you will have a little help getting them out of your yard.
Bur Oak, Mossycup Oak, Mossy Overcup Oak, Prairie Oak (Quercus macrocarpa) It has a long taproot which makes it hard to transplant but also very drought-tolerant. It is also fast growing and long-lived. Bur oak is noted for its very large leaves and acorns:.. It casts deep shade.
Bur oak blight, a new disease on Quercus macrocarpa caused by Tubakia iowensis sp. nov. A newly recognized, late-season leaf disease of Quercus macrocarpa (bur oak) has become increasingly severe across Iowa and in neighboring states since the 1990s. Vein necrosis and leaf death may occur over the whole crown... Bur oak blight appears to be particularly severe on Q. macrocarpa var. oliviformis, which is well adapted to the dry, upland sites where the disease is found most frequently... species of Tubakia are known as leaf and twig endophytes in oaks...
Parkinsonia aculeata Parkinsonia aculeata is a species of perennial flowering tree in the pea family, Fabaceae. Common names include palo verde, Mexican palo verde, Parkinsonia, Jerusalem thorn, Ratama in Spain, and (where?) jelly bean tree... The flowers are yellow- orange and fragrant, may be a spiny shrub or a small tree. It grows 2 to 8 m (6.6 to 26.2 ft) high, with a maximum height of 10 metres (33 ft).
The amazing, the incredible Anaqua Its durability and shade make it the perfect tree for South Texas
Native Plant Society of Texas: Anaqua, Ehretia anacua this is a wonderful ornamental and wildlife tree. In the spring the tree is covered with fragrant white flowers that are enjoyed by bees. These are followed 6 weeks later by edible yellow or orange fruit which are a favorite of birds and small mammals. (not good near sidewalks and driveways)
A&M on the Anaqua Ehretia anacua. Semi-evergreen. A medium-sized tree to 50 feet tall and a trunk to 2 feet in diameter, with a dense, round crown of dark green foliage. grows well on alkaline soils. Used as a landscape tree from San Antonio to Houston and southward. Interesting Facts: An important component of the evergreen forest remnants along the lower Rio Grande valley.
Anacacho Orchid Tree: Bauhinia lunarioides (B. congesta) In its native habitat in Texas it grows on rocky limestone canyons, and needs well-drained soils to thrive.
Anacacho orchid tree, Anacacho bauhinia, Orchid tree, Texas plume Anacacho orchid tree makes a gorgeous display with its silvery gray bark and fragrant white flowers that resemble orchids. It is a relatively rapid-growing tree after its first year when placed in a favorable location
Anacacho orchid tree, a great landscape plant Anacacho orchid trees apparently can grow well in understory or open-sun sites.
Italian Stone Pine Umbrella Pine, edible fruits
Pinus pinea, Italian Stone Pine Trees grow well in any slightly alkaline to acid soil. Umbrella Pine should be grown in full sun on well-drained soil... Something always seems to be falling from this pine tree; needles, sap, branches, and fruit appear on nearby cars, roofs and sidewalks year round. Unless grown in the open with no other trees nearby, shaded lower branches die as the tree grows taller. Open-grown trees keep more lower branches, probably due to greater sun exposure. It is important to maintain only one leader to the top of the plant... Dropping needles often discourage people from planting pines near streets, parking lots, or near other pavement. Roots also enjoy growing just under the surface of the asphalt and cracking it.
Bald Cypress: Taxodium Distichum Unique in its appearance, the Bald Cypress is a model of grace and endurance. Along with its massive size, other considerations should be made before choosing the proper location for this special tree. Although the Bald Cypress is native to swamplands, it will tolerate a wide range of conditions, and will even tolerate short periods of drought. In response to long periods of drought, it will completely defoliate. However, this tree is amazingly resilient, and will leaf out when adequate moisture returns. Since the Bald Cypress is so adaptable to growing in conditions ranging from excessive moisture to drought, our tight clay soils are not a challenge... This unique tree has special adaptations to living in wet environments; knobby projections called "knees" may form at the base of the trunk. These formations often occur when the tree is planted in or near water, but can occur anywhere that moisture is ample. Some say the knees add to the distinctive character of this tree.
It is one of the few coniferous trees that is deciduous. A highlight in the landscape, this tree has a pyramidal form and feathery leaves that add to its appeal. After turning bronze in the fall, the lacy leaves will drop and cover the ground with a rust-color carpet in the winter and then decompose quickly.
Tamarind Of all the fruit trees of the tropics, none is more widely distributed nor more appreciated as an ornamental than the tamarind, Tamarindus indica L. The tamarind, a slow-growing, long-lived, massive tree reaches, under favorable conditions, a height of 80 or even 100 ft (24-30 m), and may attain a spread of 40 ft (12 m) and a trunk circumference of 25 ft (7.5 m). It is highly wind-resistant, with strong, supple branches, gracefully drooping at the ends, and has dark-gray, rough, fissured bark. The mass of bright-green, fine, feathery foliage is composed of pinnate leaves,..
The fruits, flattish, beanlike, irregularly curved and bulged pods, are borne in great abundance along the new branches and usually vary from 2 to 7 in long and from 3/4 to 1 1/4 in (2-3.2 cm) in diameter. Exceptionally large tamarinds have been found on individual trees. The pods may be cinnamon-brown or grayish-brown externally and, at first, are tender-skinned with green, highly acid flesh and soft, whitish, under-developed seeds. As they mature, the pods fill out somewhat and the juicy, acidulous pulp turns brown or reddish-brown. Thereafter, the skin becomes a brittle, easily-cracked shell and the pulp dehydrates naturally to a sticky paste enclosed by a few coarse strands of fiber extending lengthwise from the stalk. The 1 to 12 fully formed seeds are hard, glossy-brown, squarish in form,
Native to tropical Africa, the tree grows wild throughout the Sudan and was so long ago introduced into and adopted in India that it has often been reported as indigenous there also, and it was apparently from this Asiatic country that it reached the Persians and the Arabs who called it "tamar hindi" (Indian date, from the date-like appearance of the dried pulp), giving rise to both its common and generic names. Unfortunately, the specific name, "indica", also perpetuates the illusion of Indian origin. The fruit was well known to the ancient Egyptians and to the Greeks in the 4th Century B.C.
In all tropical and near-tropical areas, including South Florida, it is grown as a shade and fruit tree, along roadsides and in dooryards and parks. Mexico has over 10,000 acres (4,440 ha) of tamarinds, mostly in the states of Chiapas, Colima, Guerrero, Jalisco, Oaxaca and Veracruz. In the lower Motagua Valley of Guatemala, there are so many large tamarind trees in one area that it is called "El Tamarindal".
The food uses of the tamarind are many. The tender, immature, very sour pods are cooked as seasoning with rice, fish and meats in India. The fully-grown, but still unripe fruits, called "swells" in the Bahamas, are roasted in coals until they burst and the skin is then peeled back and the sizzling pulp dipped in wood ashes and eaten. The fully ripe, fresh fruit is relished out-of-hand by children and adults, alike. The dehydrated fruits are easily recognized when picking by their comparatively light weight, hollow sound when tapped and the cracking of the shell under gentle pressure. The shell lifts readily from the pulp and the lengthwise fibers are removed by holding the stem with one hand and slipping the pulp downward with the other. The pulp is made into a variety of products. It is an important ingredient in chutneys, curries and sauces, including some brands of Worcestershire and barbecue sauce, and in a special Indian seafood pickle called "tamarind fish". Sugared tamarind pulp is often prepared as a confection. For this purpose, it is desirable to separate the pulp from the seeds without using water. If ripe, fresh, undehydrated tamarinds are available, this may be done by pressing the shelled and defibered fruits through a colander while adding powdered sugar to the point where the pulp no longer sticks to the fingers. The seeded pulp is then shaped into balls and coated with powdered sugar. If the tamarinds are dehydrated, it is less laborious to layer the shelled fruits with granulated sugar in a stone crock and bake in a moderately warm oven for about 4 hours until the sugar is melted, then the mass is rubbed through a sieve, mixed with sugar to a stiff paste, and formed into patties. This sweetmeat is commonly found on the market in Jamaica, Cuba and the Dominican Republic. In Panama, the pulp may be sold in corn husks, palmleaf fiber baskets, or in plastic bags.
Young leaves and very young seedlings and flowers are cooked and eaten as greens and in curries in India. In Zimbabwe, the leaves are added to soup and the flowers are an ingredient in salads.
Few plants will survive beneath a tamarind tree and there is a superstition that it is harmful to sleep or to tie a horse beneath one, probably because of the corrosive effect that fallen leaves have on fabrics in damp weather. Some African tribes venerate the tamarind tree as sacred. To certain Burmese, the tree represents the dwelling-place of the rain god and some hold the belief that the tree raises the temperature in its immediate vicinity. Hindus may marry a tamarind tree to a mango tree before eating the fruits of the latter. In Nyasaland, tamarind bark soaked with corn is given to domestic fowl in the belief that, if they stray or are stolen, it will cause them to return home. In Malaya, a little tamarind and coconut milk is placed in the mouth of an infant at birth, and the bark and fruit are given to elephants to make them wise.

Texas Ecoregions SA is in the Post Oak Savannah bordered on the North by Blackland Prairies, on the Southwest by the South Texas Plains, and on the Southeast by the Coastal Plains. The Post Oak Savannah is a transition zone between the blackland prairies to the west and the Pineywoods to the east. This ecosystem is part of a historic oak belt, which travels south from Canada towards Central America. Few true examples of old-growth Post Oak Savannah in Texas still exist today. South Texas Plains: Soils are primarily acidic sands. Flats with poor drainage often contain huisache and some mesquite trees. Droughty flats and ridges with gravelly or rocky soils that have better drainage contain shorter mesquite, blackbrush, cenizo, etc. Often known as the Tamaulipan Thornscrub or “brush country”, this region of Texas is known for shorter trees and numerous shrubs, most of which contain thorns. Because of the hot dry weather, leaves are commonly small and often compound. The short height and dense, small leaves give the region an appearance of impenetrable shrubland. The flats and ridges host honey mesquite, huisache, blackbrush, guajillo, cenizo, Texas mountain laurel, and Spanish dagger. Shallow arroyos or rocky draws often host additional species such as spiny hackberry, bluewood condalia, Texas persimmon, lime prickly ash, guayacan, and kidneywood.

11 of the World's Most Threatened Forests beautiful pictures
Where The Birds Come From: The Push To Protect The Boreal Forest In the northern reaches of North America lies a vast forest that extends from interior Alaska all the way across Canada to Newfoundland and the Atlantic Ocean. It provides the breeding grounds for billions of migratory birds each summer and is home to around one-quarter of the world’s remaining untouched forests. North America’s boreal forest contains a treasure trove of internationally significant ecological values, and it’s also the focus of one of the most ambitious conservation efforts anywhere on Earth.
The combination of its intactness (about 80% is still relatively intact and free of industrial disturbance) and its vast networks of wetlands and waterways (millions of lakes large and small and around 25% of the world’s wetlands) makes this lush forest a summer breeding paradise for at least 325 bird species—nearly half of the species commonly found in the U.S. and Canada.

TAMU Tree Guide shows pictures of every tree for texas
Tree Handbook An estimated 1,200 native flowering plant species grow in the lower Rio Grande Valley, Texas, and of these at least 28 species reach tree size. The Native Plant Project has selected 28 of these trees to be featured in this publication. Some are beautiful ornamentals, some prove invaluable for wildlife use, and others make excellent shade trees.
Trees native to the lower Rio Grande Valley have advantages over trees (even of the same species) brought in from elsewhere. Trees of local origin have the genetic factors which ensure greater probability for survival since they are preadapted having evolved to tolerate local climatic extremes, local soils, and local diseases and pests. Except for the few species which usually grow with their roots nearly in the water of the Rio Grande or resacas, most local native trees are xeric-adapted. This means they require little supplemental water, tolerate droughts well, and conserve much of the extra water which exotic trees require. Many fit well into xeriscapes. Native trees have evolved with the temperature and rainfall extremes and remained relatively unharmed during the Christmas freezes of 1983 and 1989 which devastated the non-native plantings. A little extra water though may greatly lengthen the flowering period of xeric-adapted trees and shrubs.
Vitex agnus-castus, also called Vitex, Chaste Tree, Chasteberry, Abraham's Balm or Monk's Pepper, is a native of the Mediterranean region. It is one of the few temperate-zone species of Vitex, which is on the whole a genus of tropical and sub-tropical flowering plants. Theophrastus mentioned the shrub several times, as agnos (?????) in Enquiry into Plants. Vitex, its name in Pliny the Elder, is derived from the Latin vieo, meaning to weave or to tie up, a reference to the use of Vitex agnus-castus in basketry.
Vitex agnus-castus is widely cultivated in warm temperate and subtropical regions for its delicate-textured aromatic foliage and butterfly attracting spikes of lavender flowers in late summer in cooler climates. It grows to a height of 1–5 meters. It requires full sun or partial shade along with well-drained soil.
In ancient times it was believed to be an anaphrodisiac, hence the name chaste tree. Pliny, in his Historia Naturalis, reports the use of stems and leaves of this plant by women as bedding "to cool the heat of lust" during the time of the Thesmophoria, when Athenian women left their husbands' beds to remain ritually chaste. At the end of the thirteenth century John Trevisa reports of it "the herbe agnus-castus is always grene, and the flowre therof is namly callyd Agnus Castus, for wyth smel and vse it maketh men chaste as a lombe". Chaucer, in "The Flower and the Leaf," refers to it as an attribute of the chaste Diana, and in the 16th century the English herbalist William Turner reports the same anaphrodisiac properties of the seed, both fried and not fried. More recently, this plant has been called monk's pepper in the thought that it was used as anti-libido medicine by monks to aid their attempts to remain chaste.
There are disputed accounts regarding its actual action on libido, with some claims that it is anaphrodisiac and others that it is aphrodisiac. Because of the complex mechanism of action it can be probably both, depending on concentration of the extract and physiologic variables (Wikipedia).
After the leaves have fallen off in autumn, the pea-sized dried berries can be collected for use as food or medicine. (Google) Chaste tree (Vitex agnus-castus var. latifolia)--These plants are happiest in full sun and well-drained soil. Problems: Leaf spot, root rot, or scale insects. Read more: http://www.finegardening.com/chaste-tree-vitex-agnus-castus-var-latifolia#ixzz3i3kBwEXJ Follow us: @finegardening on Twitter | FineGardeningMagazine on Facebook[finegardening.com] See TAMU comments at http://aggie-horticulture.tamu.edu/newsletters/hortupdate/2008/jun08/Vitex.html The early American nurseryman Peter Henderson stated that Vitex has been cultivated here since 1670. For folks in the warmer part of the South, the "Lilac Chaste Tree" has been the shrub of choice to mimic lilacs, which are restricted to cooler regions. Vitex is an excellent choice for a large shrub or small flowering tree in the smaller, modern suburban landscape. It does best in full sun and will grow in a variety of soils, provided they are well drained. After it has been established, the Vitex is a good candidate for planting in a xeric garden, where hot, dry surroundings prevail. Like many members of the Vervain family, Vitex attracts butterflies and other insects. The older strains had small spikes of flowers in pale lilac, mauve, off-white or light pink, but modern, much improved varieties such as 'Montrose Purple', 'LeCompte', or the pink 'Salinas Pink' have spikes as long as 8 to 12 inches in length. Many aromatic black or brown seeds may be set, but if the spent spikes are cut off promptly after the first flowering the shrub will bloom again. VitexSouthern Living [http://thedailysouth.southernliving.com/2009/06/19/chaste-tree-is-pure-delight/] my favorite tree of the bunch.. quickly grows into a multi-trunked tree about 10 to 20 feet tall and wide with a broad, spreading habit. pharmacological uses. An extract made from Vitex supposedly does a very good job of controlling PMS. Which means any of you guys out there who are routinely beaten every 28 days should definitely plant one in the yard.
But the best thing about chaste tree, in my uber-learned opinion, is the flowers. Chaste tree is one of the very few winter-hardy trees out there that sports true blue flowers (although they can also be pink, purple, or white). The one you’re looking at here is ‘Abbeville Blue.’ which bears large, spectacular panicles of deep-blue flowers in summer. Other selections I like include ‘Montrose Purple’ (purple blooms), ‘Shoal Creek’ (blue-violet), and ‘Silver Spires.’ (white). If you buy an unnamed chaste tree tree from a nursery, buy it in bloom so you can see the color of the flowers and the general shape of the plant.
Few trees are as easy to grow. Here’s the low-down:
Light: Full sun
Water; Regular moisture at first — very drought tolerant once established
Pests: None serious
Pruning: Not the tidiest plant in the world. Needs regular pruning to produce an attractive multi-trunked tree. Prune in winter. Clean out the entire center of the tree, removing all side branches from main 4 to 5 trunks. Also remove messy, twiggy growth that tends to crowd the ends of the branches. As an option, cut entire plant to ground in winter. It will sprout in spring and bloom in summer, although later than chaste trees not pruned so severely. You can also force a second bloom in summer by removing the first flush of blooms as soon as they fade.
Salt & wind tolerance: Good

Cordia boissieri Cordia boissieri is a species of flowering shrub or small tree in the borage family, Boraginaceae. Its native range extends from southern Texas in the United States south to central Mexico. Common names include Anacahuita, Mexican Olive, White Cordia, and Texas Wild Olive.
A small tree with a curving trunk, to 20 feet tall and a trunk to 12" in diameter, with a low, rounded crown.
Native to the brushlands and forest remnants of the southernmost tip of Texas, this species is a beautiful landscape tree that can be planted as far north as San Antonio.
Simple, opposite on the twigs, oval to oblong, 4" to 5" long by 2" to 3" wide, leaf edge without teeth, velvety on both surfaces, evergreen.
Very showy, white, trumpet-shaped flowers, 1.5" long and 2" wide, with a yellow spot in the throat, appear throughout spring and summer with sufficient water.
A whitish drupe, about 1" long, with sweet, pulpy flesh. Favored by wildlife and edible by humans.
Gray to light brown, strongly fissured with flat ridges even on small stems, fibrous and interwoven.
Wood is sometimes used for woodenware and yokes. Sold principally as a landscape tree.
Buttonbush (Cephalanthus occidentalis) has smooth leaves 3" to 8" long; white fringetree (Chionanthus virginicus) occurs in East Texas and has smooth leaves.
Jelly made from the fruits is used as a household remedy for coughs and colds.
ANACAHUITA, TEXAS OLIVE, MEXICAN OLIVE, WILD OLIVE Cordia boissieri---Also called the Texas Olive, this rare native makes a beautiful small specimen tree perfect for the hottest toughest sunniest areas so long as the soil is well-drained. The Anacahuita produces large clusters of 2", crepe-like, white funnel shaped flowers with a dark gold yellow throat in spring and early summer as well as again in fall. The large olive-like fruit ripens to white before falling from the tree. The ripe fruit may be too much for some situations but it is relished by birds and other wildlife but are known to make the animals dizzy when eaten in any quantity.
There are some beautiful specimens at the Alamo in San Antonio, Texas.
NATIVE PLANT DATABASE: NATIVE PLANT DATABASE: Cordia boissieri Locally known as Mexican olive or Anacahuita, Cordia boissieri is an ornamental shrub or tree to 30 ft, with large, soft, dark leaves and large, showy, trumpet-shaped white flowers with yellow throats that are sometimes described as looking like crepe paper or chiffon. Its sinuous trunk becomes picturesque as it ages. It is native no farther north than south Texas because it cant tolerate cold winters, but it has been successfully tried as far north as Austin, where cold winters are likely to cause some die-back. Within its natural range, it is drought-tolerant enough that it is a common highway planting. Birds, deer, and cattle enjoy the sweet 2-3 cm long fruit and butterflies frequent the blooms.
Native Plant Base: Mountain Laurel Sophora secundiflora (Ortega) Lag. ex DC. Texas mountain laurel, Mountain laurel, Mescal bean, Mescal bean sophora, Frijolillo, Frijolito Fabaceae (Pea Family)
Mescal bean or Texas mountain laurel is an evergreen, usually multi-trunked shrub or small tree ranging from just a few feet tall to more than 30 ft. in height, though its usual height at maturity is 10-15 ft. The dense, dark green, and glossy compound leaves are composed of 7–9 shiny, leathery leaflets that are rounded on the ends. The leaflets are up to 2 inches or more long, tapering more gradually to the base than to the tip, and arranged along an axis terminated by a single leaflet . The bluish lavender flowers, in 3-7 in. drooping clusters, are very showy and fragrant. The fruit is a semi-woody pod with bright red poisonous seeds.
Sophora secundiflora is very popular as a native evergreen ornamental tree within its range, valued for its handsome, dark green foliage and lush early spring blooms. It is drought-tolerant, prefers rocky limestone soil, and is native from central Texas west to New Mexico and south to San Luis Potosi in Mexico. Like many woody plants native to rocky soils, it is slow growing. The fragrance of Texas mountain laurel flowers is reminiscent of artificial grape products. The brilliant, lacquer red seeds were valued by indigenous people for ornament and ceremonial use; they contain the highly poisonous alkaloid cytisine (or sophorine), a substance related to nicotine and widely cited as a narcotic and hallucinogen.
Dermatophyllum secundiflorum Dermatophyllum secundiflorum is a species of flowering shrub or small tree in the pea family, Fabaceae, that is native to the southwestern United States (Texas, New Mexico) and Mexico (Chihuahua and Coahuila south to Hidalgo, Puebla and Querétaro). Common names include Texas mountain laurel, Texas mescalbean, frijolito, and frijolillo. Although "mescalbean" is among the plant's common appellations, it bears no relation to the Agave species used to make the spirit mezcal, nor to the peyote cactus (Lophophora williamsii), which contains the hallucinogenic alkaloid mescaline.
It is well-adapted to arid and semi-arid habitats but is most common in riparian zones. [A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the fifteen terrestrial biomes of the earth.]
Extremely fragrant purple flowers, resembling the smell of grape soda, are produced in large clusters in March and April. They are followed by 4 in (10 cm) pods containing deep orange seeds.
Arid Zone Trees PDF Of the four common names associated with this plant, Sophora, Texas Mountain Laurel, Frijolito and Mescal Bean, Sophora is the most widely used. Native to Texas, New Mexico and northeastern Mexico, Sophoras are well adapted to high temperatures, well drained alkaline soils and full sun. They typically grow quite slowly eventually reaching a mature height of 15 to 20 feet and 8 to 10 feet wide.
Its slow rate of growth to mature height has led some to categorize it as a large shrub/small tree.
The form is usually low branching or multiple trunked with a dispersed to fairly dense canopy of glossy green leaves. In native settings they are found growing at elevations from 1000' to 5000'. Sophoras can be naturalized to survive on average annual rainfall alone in some desert settings. Supplemental summer irrigations are usually required in central and southern Arizona. The highest rate of growth is achieved on established Sophoras when they are planted in full sun and given deep, monthly irrigations during spring and summer. The leaves are compound (made up of smaller leaflets) with 7 to 9, round, 1 inch diameter leaflets. With proper pruning, Sophoras can be trained into the form of a small, multiple trunked tree. Be aware that excessive pruning can inhibit flower production, as Sophora’s produce flowers only on one year old wood. Trunks range in color from dark gray to black.
Established plants are hardy to 0 degrees F. In March and April 4" to 8" bright purple, drooping clusters of wisteria-like flowers are produced. These flower clusters are very fragrant with a smell resembling grape soda. Flowers fade fairly quickly and by mid summer give rise to 3" to 4" fuzzy, tan, seed pods.
The seeds are large, 3/8" to 1/2" diameter and dark orange in color. Seeds and flowers can be poisonous to children and pets. The risk is limited as the seed pod and seed coat are very hard and difficult to crack. Placement and maintenance of this shrub should take into account the risk posed by the flowers and seeds.
Sophoras can be used as individual flowering shrubs, in groupings to exploit the glossy green foliage, purple flowers and remarkable fragrance or as a screen or hedge planting. It mixes easily with other desert landscape plant materials and adds a unique color and texture to the landscape. It will tolerate planting in or near turf or in more native areas.
Sophoras are thornless.
The only insect pest of any consequence is the larvae of the Pyralid Moth that feeds on leaves, young twig growth and immature seed pods. It is readily controlled by application of Bacillus thuringiensis (sometimes called BT), a widely available, commercial biological control agent. Sporadic availability and the relatively slow growth rate have limited the use and popularity of this shrub. Proper maintenance can enhance the growth and increase the popularity of this remarkable yet under-appreciated flowering desert shrub.
Mountain Laurel Usually found as a multi-trunked small tree, Texas mountain laurel can be trained to a single trunk in the nursery. Single-trunked nursery stock would make nice street trees for planting in small soil spaces, and where overhead space is limited by wires or other structures. Plant a row of Texas mountain laurel on 15 or 20 foot centers to form a nice canopy over a walk, or locate it close to a patio or deck. The bark on multi-trunked specimens shows off nicely when lit up at night from beneath the canopy.
Texas mountain laurel should be grown in full sun or partial shade on well-drained soil. This tough plant will tolerate hot, windy conditions and alkaline or wet soils but not compacted soil. Young trees may benefit from afternoon shading from the intense summer sun until they become established.
Sophora secundiflora beans are hallucinagenic
Texas Mountain Laurel, Mescal Bean Probably one of my favorite shrubs. It is slow growing, but can be pruned into a nicely shaped small tree given sufficient time. My plant thrives incredibly well planted next to a southwest facing block wall that receives punishing reflective heat during the Phoenix summer. It seems the hotter it is, the better this plant will grow. Stays evergreen throughout the year and from February-March its flowers produces a marvelous scent rivaled only by freesia. The Texas Mountain Laurel is a host plant for gentista broom moth caterpillars. In early spring and middle of the fall, the freshest growth is defoliated by these caterpillars which form a silk-like tent around the ends of the branches.
Texas Mountain Laurel, Mescal Bean, Frigolito, Frijollito, Frijolillo, Coral Bean, Big-drunk Bean, Colorin Texas mountain laurel grows in limestone soils in Central and Southwest Texas and to 5000 feet in the Chisos and Davis Mountains. This slow growing evergreen may be grown as a medium to large shrub or trained to a single or multi-trunk tree. The pinnate leaves with their lustrous, leathery upper surface provide year long beauty, enhanced in mid-spring by the densely-flowered racemes of lavender or violet pea flowers having the scent of grape Kool Aid. The black, somewhat constricted seedpods contain red to red-orange seeds which are sometimes used in jewelry. Both seeds and flowers are quite poisonous and contain narcotic properties
Red Bud The Redbud grows throughout much of the eastern United States and extends as far west as Texas, Oklahoma and Kansas.
Hardiness Zones: 4 to 9
Height: 30 ft
Spread: 25 ft
Type: deciduous tree
Annual Growth Rate: 12 to 18 inches

Cultivar 'Forest Pansy' - The new leaves are scarlet becoming maroon as they mature. The flowers are pink. This cultivar may not be as hardy as the species.
Cultivar 'Flame' ('Plena') - Double pink flowers appear at the same time as the leaves. Seldom sets fruit.
Cultivar 'Silver Cloud' - The leaves are variegated with pink and white. The plants are 12 feet tall and wide.
Treehoppers lay eggs under the bark of twigs. The insect itself is not seen but the white, sticky froth covering the eggs is quite noticeable (see image). The insect is seldom serious. Use Horticultural Oil in a dormant spray dosage to control treehoppers. The Horticultural Oil should be applied when the temperatures are between 35 and 85 degrees Fahrenheit.
Scale insects are small, non-mobile insects that attach themselves to the wood and sometimes the foliage. Scale is most common on the new tender woody growth. When adult scale is attached to the tree, it often appears as crusty or waxy bumps on the tree and is often mistaken for part of the tree’s own growth, but it is actually an insect. The scale sucks sap from the tree and causes the leaves to turn yellow and drop. Often a sticky substance can be found near the scale or on the leaves. This is a secretion from the scale called honeydew and often acts as an attractant for ants or as a growing source for sooty mold.
In the spring or mid-summer, small, almost invisible nymphs emerge from under the female shells and move to infect new areas of the tree. This is the only time in the life cycle of scale that the insect moves.
To effectively control scale insects and limit damage, Horticultural Oil should be sprayed on the tree. The Horticultural oil serves to suffocate the scale and eggs. In the spring or early summer if the crawling nymphs are present, spray the trees with [Bug Buster] to prevent the new nymphs from further infecting the tree.
Spider mites are an extremely tiny pest, and generally appear as a brown, red or purple specks on the underside of leaves. Mites infest leaves and cause the leaves to appear speckled with yellow spots or wilted and curled. A fine silken webbing can sometimes be seen on the underside of the leaves. Intense infestations during hot, dry weather can cause the leaves to curl and drop.
To confirm if the tree has a spider mite infestation take a close look at the undersides of the leaves for small insects, the size of ground pepper. You may need to use a small magnifying glass to adequately see the spider mites. Another way to examine for spider mites is to take a sheet of white paper, hold it under a group of leaves and give the leaves a few sharp taps to shake some of the spider mites loose. On the white paper the spider mites can be easily seen.
Spider mites damage the tree by sucking sap from the underside of the leaves. The bite marks appear as a yellow speckled pattern on the top and bottom of the leaf. As the season progresses and the temperature becomes hotter and dryer (above 70 degrees F.) the population of spider mites will increase exponentially and can rapidly defoliate a tree, especially if the tree is having trouble taking up water during drought periods. To control mites, spray the tree with Bug Buster. Be sure to spray the underside of the leaves as well as leaf crotches as this is where most spider mites and their eggs are found.
Dieback/Canker is the most destructive disease that attacks Redbud trees. It is first seen as a tree’s leaves wilt and turn brown. Often cankers can be seen on branches and twigs. The cankers can either be seen as visible cankers on the surface of the branches or as dark sunken areas with black centers.
The canker or dieback is caused by a fungus (Botryosphaeria ribis) which attacks not only the redbud but more than fifty other types of trees and shrubs. The disease is spread throughout the tree, or from tree to tree, by splashing rain and winds that move the fungus from diseased areas to healthy parts of the tree. The fungus then enters the tree through wounds or dying branches. The fungus gradually spreads out within the tree’s vascular system slowly blocking the tree’s vascular system and inhibiting its ability to transport nutrients and water. The result is a gradual dieback of branches as the flow of nutrients and water is cut off.
There is no effective chemical control for the canker. If canker is identified in a tree, prune out and destroy dead branches and infested areas. Be sure to make pruning cuts at least 3 or 4 inches below the canker, so that the cut is into healthy viable wood. After every pruning cut, be sure to properly sanitize the pruning tools so that the fungus is not transported on the tools and infects healthy parts of the tree.
What Time of the Year to Plant a Redbud Tree Redbud, like most trees, grows best when planted during cool, rainy weather. During hot weather, it suffers more transplant shock and might be slow to develop a root system. When the ground is frozen, its roots cannot move through the soil. Planting a redbud tree during very cold weather also can cause it to dry out. Depending on your climate, the best time to plant any tree is usually in spring or early fall, according to the Virginia Department of Forestry's website. In mild climates, however, a tree can be planted in winter.
Choose the planting location for a redbud tree carefully. It can tolerate partial shade but grows and blooms better if placed in a site that has full sun exposure. A redbud tolerates most kinds of soil as long as it drains well.
How you plant a redbud tree is as important as when you plant it. A redbud doesn't tolerate heavy clay or compacted soil that tends to drain poorly. Break up such soil, and amend it with compost to lighten its consistency. The planting hole for your redbud tree should be twice as wide and almost as deep as the tree's root ball. The top of the root ball should sit 1 to 2 inches taller than the soil surrounding the hole. Don't worry about adding fertilizer to the planting hole, but water the tree regularly during dry weather for its first growing season or its first two growing seasons. Once established, a redbud tree needs infrequent watering, depending on its species.
Red Bud Adaptable and dependable, redbuds include some of our most charming native trees. In early spring, before leaf-out, a profusion of small, sweet pea–shaped, lavender-pink to rosy purple flowers appears on twigs, branches, and even the main trunk. Blossoms are followed by clusters of flat, beanlike pods that persist into winter and give rise to numerous seedlings around the tree. Handsome, broad, rounded or heart-shaped leaves may change to bright yellow in fall, but fall color is inconsistent.
Growing Redbud Trees: How To Care For A Redbud Tree Growing redbud trees is a great way to add brilliant color to your landscape. In addition, the care of redbud trees is easy. Planting a redbud tree is best done in early spring. These ornamental beauties prefer well-drained soil and a partly shaded location.
The care of redbud trees requires minimal effort. Place about 3 inches of mulch around the tree, but not touching the trunk, to help retain moisture.
Prune the redbud in the fall to maintain a natural growth habit and to trim off any dead branches.
Keep the soil moist, but not saturated, while the tree is establishing.
Fringe Tree — The Best Native Tree Nobody Grows Grumpy Gardener in Southern Living
You’d think a small, native tree with pretty spring flowers and pretty fall foliage that’s easier-than-pie to grow would be a staple in our gardens. You’d be wrong. So let me tell you about fringe tree.
Fringe tree (Chionanthus virginicus) has always played twelfth fiddle to dogwood, saucer magnolia, flowering cherry, Bradford pear (yuck), and numerous others choices for spring-flowering trees. That’s just wacky. Indigenous to the eastern U.S., it grows from Canada all the way down to the Gulf Coast. It’s tougher than dogwood, more dependable than saucer magnolia, longer-lived than cherry, and smells better than stinky Bradford. And it’s beautiful.
Fringe tree gets its name from its clouds of fleecy white, softly fragrant flowers that hang from the branches in late spring and early summer. Other common names here in the South are grancy graybeard and old man’s beard. Trees can be either male or female. Males sport larger, showier blooms, but females form attractive, blackish-blue fruits that birds like. Nurseries don’t sell trees by sex, so you have to take your chances. But either sex is well worth planting.
Size: 12 to 20 feet tall and wide
Shape: Rounded and usually multi-trunked
Light: Full to partial sun
Soil: Moist, fertile, well-drained
Water needs: Moderate, tolerates some drought
Fall foliage: Bright yellow
Hardiness zones: USDA Zones 3-9 (we're 8)
Prune: Seldom needed; prune after flowering
Bonus fact: Tolerates air pollution; good for city gardens
Bonus bonus fact: One of the last trees to leaf out in spring
Jacaranda is a genus of 49 species of flowering plants in the family Bignoniaceae, native to tropical and subtropical regions of Central America, South America, Cuba, Hispaniola, Jamaica and the Bahamas. - Wikipedia
Northern Catalpa [Catalpa speciosa] This is a tree that demands your attention. White, showy flowers. Giant heart-shaped leaves. Dangling bean-like seed pods. Twisting trunk and branches. How could you not stop to take it in?
Catalpa Northern catalpa is a medium to large, deciduous tree that typically grows to 40-70’ (less frequently to 100’) tall with an irregular, open-rounded to narrow-oval crown. It is native to a relatively small area extending from western Tennessee, northeastern Arkansas and the lowlands of southeastern Missouri north to southern Illinois and southern Indiana. In Missouri, it typically occurs along streams, bluff bases and in both low and upland woods (Steyermark). Broad ovate to ovate-oblong leaves (to 12” long) are pointed at the tips and rounded to cordate at the bases. Leaves are light green to yellow green above and densely pubescent below. Foliage turns an undistinguished yellow in fall. Flowers can be a real showstopper, however. Bell-shaped, orchid-like white flowers (to 2” long) with purple and yellow inner spotting appear in panicles in late spring (late May to early June in St. Louis). Flowers give way to long slender green seedpods (12-22” long). The seedpods mature in fall to dark brown and then split open lengthwise to release the seeds within. Seedpods give rise to the common name of cigar tree, although they actually are longer and thinner than most cigars. Abundant pods are produced every 2 to 3 years. Bark of mature trees is fissured, prominently ridged and pale gray-brown. The leaves of this species do not emit an unpleasant aroma when bruised as is the case with the similar southern catalpa (Catalpa bignonioides).
A mature, symmetrically rounded catalpa tree can be a tree of great beauty, particularly in spring when the foliage is young and the flowers are in bloom. Unfortunately, it is otherwise a rather coarse tree that many believe does not deserve a prominent place in the landscape. Branches are brittle and mature trees infrequently exhibit classic form. Foliage also tends to depreciate as the growing season progresses, the large leaves being subject to damage from hail, wind, insects and sometime disease. It has been widely planted in urban areas as a street tree and lawn tree, and can also be effectively used in the landscape for difficult areas such as moist low spots or dry areas with poor soils.
Rhamnus caroliniana Rhamnus caroliniana (syn. Frangula caroliniana), the Carolina buckthorn, is an upright shrub or small tree native to the southeastern, south-central, and mid-western parts of the United States, from Texas east to Florida and north as far as Maryland, Ohio, Missouri, and Oklahoma. There is also an isolated population in the State of Nuevo León in northeastern Mexico.
Rhamnus caroliniana is usually around 12 to 15 feet (3.6-4.5 meters) high, but capable of reaching 40 feet (12 meters) 25/3in a shaded location. The most striking characteristic of this plant are its shiny, dark green leaves. The flowers are very small and inconspicuous, pale yellow-green, bell-shaped, appearing in leaf axils in late spring after the leaves. The fruit is a small (1/3 inch or 8.3 mm) round drupe; at first red, but later turning black with juicy flesh. It ripens in late summer. Despite its common name, the Carolina Buckthorn is completely thornless.
Crape Myrtles for Texas a collaborative project of Texas Cooperative Extension, Texas Agricultural Experiment Station, Texas A&M University, and the Texas Nursery and Landscape Association.
Crapemyrtle The crapemyrtle is often referred to as the "lilac of the South." With its striking flowers, handsome bark and attractive foliage, this species is a favorite for landscapes. It can be grown as either a shrub or small tree and is often used in groupings, containers, hedges and screens. You can even find the common crapemyrtle used as small street trees in urban settings.
The Crape Myrtle Co. We have over 55 varieties available of miniature, dwarf, medium and standard (tree) crape myrtles. Crape Myrtles are great for landscaping, ground cover, hanging baskets, bonsai, shrubs, privacy hedges and beautiful specimen trees.
Complete Guide to Crape Myrtle All crepe myrtles bloom on new wood and should be pruned in winter or early spring. On large shrubs and trees, remove basal suckers, twiggy growth, crossing branches, and branches growing toward the center of the plant. Also gradually remove side branches up to a height of 4–5 ft.; this exposes the handsome bark of the trunks. During the growing season, clip off spent flowers to promote a second, lighter bloom.
Mildew can be a problem. Spray with triforine (Funginex) before plants bloom, or grow mildew-resistant hybrids of L. indica and L. fauriei. Almost all selections with names of Native American tribes, such as ‘Hopi’, ‘Miami’, and ‘Zuni’, are mildew resistant.
Queen’s Crepe Myrtle. L. speciosa. Zones TS; 12–9. Tree to 25–30 ft. tall, 15–25 ft. wide. The showiest and most tender of the crepe myrtles, displaying huge clusters of white, pink, lavender, or purple flowers in June and July. Individual blossoms reach 3 in. across. Large leaves (8–12 in. long, 4 in. wide) turn red in fall. Smooth, mottled, exfoliating bark. Rank grower; annual pruning in winter is especially important to control size and form.
Chilopsis It is a shrub or tree native to the southwestern United States and Mexico. The common name is desert willow or desert-willow because of its willow-like leaves, but it is a member of the bignonia family, Bignoniaceae. It is commonly seen in washes and along riverbanks
Ranging from 1.5 to as much as 8 meters in height, it can take the form of a shrub or small tree. The linear, curved, deciduous leaves are 10 to 26 cm long and just a few millimeters wide.
The generic name is derived from the Greek words χειλος, (cheilos), meaning "lip," and ′οψσις (opsis), meaning "resembling," referring to the flowers. They occur in a terminal panicle or raceme, blooming in May through September. About two to four flowers at a time are open in each inflorescence.
It is cultivated for its large, showy flowers, and tolerance of hot, dry climates. Although the natural growth is a very irregular shape, it can be readily pruned into a conventional tree shape. A number of cultivars have been selected. Some, such as 'Rio Salado', have dark purple or magenta flowers.
Chilopsis may survive temperatures as low as 10 degrees F (-12 °C).
Chilopsis is closely related to the genus Catalpa and hybrids can be made between the two genera. The nothogeneric hybrid between Chilopsis linearis and Catalpa bignonioides has been named ×Chitalpa tashkentensis. It originated in a botanic garden at Tashkent in Uzbekistan.
Chitalpa × Chitalpa is an intergeneric hybrid flowering tree in the family Bignoniaceae, bred from Desert Willow (Chilopsis linearis) for desert hardiness and color, and Southern Catalpa (Catalpa bignonioides) for larger blooms. The name is nothogeneric, or a combination of the two parents' names. Leaves are lanceolate, 4 to 5 inches long and an inch wide, almost always in whorls of three. The trumpet-shaped flowers are 1" long and frilly. The inflorescence is indeterminate, with alternately arranged flowers.
× Chitalpa is dry-spell tolerant and fast-growing (several feet a year to 20–30 ft.) and blooms between late spring and late fall. There are two cultivars: 'Pink Dawn' with pink flowers, and 'Morning Cloud' with white and pale pink blooms.
× Chitalpa tashkentensis Best grown in deep, moderately fertile, medium moisture, well-drained soils in full sun to part shade. Although drought tolerant, trees generally perform best with consistent and even moisture. Trees may sucker at the base. Propagate by cuttings. This hybrid will not produce viable seed.
No serious insect or disease problems. Powdery mildew can be a significant problem in growing areas with high summer humidity (e.g., the southeastern U. S.) and in growing conditions where trees are planted in too much shade. Additional disease problems include verticillium wilt, root rot and leaf spots. Watch for aphids, mealybugs, scale and whiteflies.
Garden Uses: Interesting medium-sized landscape or street tree with a long summer flowering period.
Eve's Necklace, Texas Sophora, Pink Sophora, Necklace Tree, Sophora affinis Eve's Necklace is a pretty small tree that is found on limestone soils in the center of the state from north central Texas through the Edwards Plateau. The dark lustrous green leaves are borne in a rounded to upright oval crown. In spring it produces rosy-pink flowers that hang in wisteria-like clusters, followed by fruit pods in late summer and fall that resemble a black string of beads, giving it its common name. The seeds are reportedly poisonous. Eve's Necklace can grow in sun or as an understory tree; in dense woods it can even be vine-like. It is related to Texas Mountain Laurel, Sophora secundiflora, which is evergreen.
Eve's Necklace, Texas Sophora, Sophora affinis From Lake Dallas, Tx: Very cool little tree that needs little care but benefits from an organic program. I found a horned caterpillar on mine last fall for several weeks which would suggest its a host plant. This is a good replacement for Japanese Maples and has the same upright and slender branching pattern. Native to Dallas. Waxy leaves have not scorched yet during droughts.
From Copperas Cove, Tx: In the southern U.S., this native Sophora grows to a small (under 15') shrub or tree with rounded crown. Tolerates full hot sun and humidity very well. Drought tolerant and withstood the ice storm we had in Feb 2003. The blooms are a reddish pink/mauve color and resembles a wisteria-type bloom about half the size. The seed pods are a "string of pearls" that are black. They dry on the tree and hang for a long time.
The plant is a large shrub or small tree growing to 5–10 m tall, with a dense crown. The leaves are semi-evergreen, oval to diamond-shaped, 4–8 cm long, with a serrated margin. The flowers are off-white, 2 cm diameter. The fruit is a globose to oblong orange-red pome 2 cm long and 1.5 cm diameter, ripening in late winter only shortly before the flowers of the following year.
The fruit is eaten in Mexico cooked, raw, or canned. It resembles a crabapple, but it has three or sometimes more brown hard stones in the center. It is a main ingredient used in ponche, the traditional Mexican hot fruit punch that is served at Christmas time and on New Year's Eve. On Day of the Dead tejocote fruit as well as candy prepared from them are used as offerings to the dead, and rosaries made of the fruit are part of altar decorations. A mixture of tejocote paste, sugar, and chili powder produces a popular Mexican candy called rielitos, because it resembles a tiny train rail.
Crabapple Trees Few ornamental trees offer the variety of tree shapes, sizes, flower colors and ornamental fruit as flowering crabapples. There are over 35 species and 700 cultivated varieties of crabapples and have been a part of the home landscape for many years.
Blossoms often open from pink or red buds and change to paler shades after opening, creating a beautiful pink cloud lasting several weeks. Asian crab apple specimens are usually preferred for ornament because their fruits are more colorful and last into the winter providing food for over-wintering birds.
Crab apples are most popular of the spring-flowering trees in the North and Midwest where cold winters and heavy soil prevent other spring bloomers from performing well.
Tree height may be from 6' - 50' with most in the 15' to 25' range. The varieties vary from weeping, spreading, columnar, vase-shaped to pyramidal which allows many opportunities for use in landscapes.
In some cases, crabapples have developed a poor reputation as a result of disease problems (scab, mildew, and fire blight) as well as susceptibility to certain insect pests such as Japanese beetle. However, extensive breeding and evaluation projects have resulted in numerous selections that are resistant to these problems.
Pruning should be completed before early June. By mid-June to early July, flower buds for the next season are beginning to form in most crabapples. Pruning after July will reduce floral display and fruiting for the following year.
Selection, Care, and Use of the Ornamental Crabapple Flowering crabapples are adaptable but thrive in rich loam type soil (a combination of clay, silt, and sand). Regardless of soil type, good drainage is a must for tree health. Crabapples grow best in a moist, slightly acidic soil with a pH of 5.0 to 6.5. Excessively moist areas and low spots should be avoided. On the other hand, relatively dry sites can be tolerated by crabapples if plant stresses are minimized during the first year after transplanting.. Full sun exposure, 8 to 12 hours of direct sun, is required for optimal development of fruits and flowers.
Sargent Crabapple Malus sargentii Because of its size, the Sargent crabapple is useful for planting under utility lines, in confined yards, as privacy screens and hedges and on sloping ground. Hardiness Zones 4–8. The Sargent crabapple grows in all textures of soil, alkaline to acidic. It prefers moist, well-drained soil but will tolerate drier conditions. Produces fragrant clusters of snowy white blossoms in May. It is an alternate bearer, blooming heavily every other year.
Wildlife Value: The pea-sized fruits make is easy for birds of many species to pluck and swallow. They are especially favored by cedar waxwings, robins, grosbeaks, and mockingbirds. Red-necked pheasant, cottontail rabbit, red fox, and black bear also enjoy the fruit. The tree's dense foliage has the added value of providing protective shelter.
Crataegus Crataegus (from the Greek kratos strength and akis sharp, referring to the thorns of some species) commonly called hawthorn, thornapple, May-tree, whitethorn, or hawberry, is a large genus of shrubs and trees in the family Rosaceae, native to temperate regions of the Northern Hemisphere in Europe, Asia and North America. The name "hawthorn" was originally applied to the species native to northern Europe, especially the common hawthorn C. monogyna, and the unmodified name is often so used in Britain and Ireland. The name is now also applied to the entire genus and to the related Asian genus Rhaphiolepis. The name haw, originally an Old English term for hedge, applies to the fruit
Hawthorns provide food and shelter for many species of birds and mammals, and the flowers are important for many nectar-feeding insects. Hawthorns are also used as food plants by the larvae of a large number of Lepidoptera species; see List of Lepidoptera that feed on hawthorns. Haws are important for wildlife in winter, particularly thrushes and waxwings; these birds eat the haws [fruit] and disperse the seeds in their droppings.
The "haws" or fruits of the Common Hawthorn, C. monogyna, are edible but the flavour has been compared to over-ripe apples. In the United Kingdom, they are sometimes used to make a jelly or home made wine. The leaves are edible and, if picked in spring when still young, are tender enough to be used in salads. The young leaves and flower buds, which are also edible, are known as "bread and cheese" in rural England.
Types Of Hawthorn Trees: How To Grow Hawthorn In The Landscape Growing hawthorn plants comes with its share of problems because they are susceptible to a number of diseases, including apple scab, fire blight, leaf spots, leaf blights and several types of rust. Some of the diseases are potentially fatal, and they leave the foliage and twigs looking tattered by the end of the season. If you decide to grow a hawthorn tree, look for a disease resistant variety such as ‘Winter King’ or ‘Washington’ hawthorn.
Hawthorn trees need full sun and well-drained soil. They tolerate almost any type of soil and variations in pH.
Set the trees out in spring so they’ll have a full season to become established before winter. In large settings they look great in groups, and they are pretty enough to stand alone as specimens in small gardens. Although they make great lawn and street trees, avoid planting thorny varieties where children play or where pedestrians pass. The thorns are fierce, and can be as much as three inches long.
Feed hawthorns annually for the first three years with a balanced fertilizer and every other year thereafter.
Hawthorn trees need little pruning. Remove suckers that arise from the base of the trunk. You can trim the canopy, if necessary, to keep it looking neat. Make cuts just beyond a lateral twig or bud that faces the direction in which you want the branch to grow.
You might want to make routine spraying a part of your hawthorn tree care plan. Hawthorns are bothered by lace bugs, aphids, mites and scale, and these insects can get out of control unless you treat them early. Use a lightweight horticultural oil early in the season. You can damage the tree by spraying with horticultural oils at the wrong time, so read the label instructions carefully before spraying. Use a general-purpose spray labeled for hawthorn trees later in the season.
We don’t have a lot of choices for shady yards, and that list is even shorter for plants with blooms as beautiful as these. It can also take a sunny spot in your garden, where it will get a little bigger: up to 30 feet tall. It has a shrubby, multi-trunked habit, but you can easily tame that to a single trunk if you want it to be more tree-like. Mexican buckeye doesn’t need too much water, but it needs a little; about as much as other shade-loving plants. It can take slightly heavy soil, but it prefers good drainage, or even soil that’s a little on the porous side. And it doesn’t need much pruning, except to give it a little shape if you want to. It’s not susceptible to cold and even has very attractive fruit, so all-in-all, you just can’t beat it!

The Washington Hawthorn is a small, colorful tree that will brighten any landscape. Its pleasant display begins with reddish-purple leaves emerging in spring, then turning dark green as they are joined by a graceful display of white flowers. In autumn, the leaves turn orange, scarlet or purple. Red berries extend the colorful show into winter, often contrasting beautifully with the first winter snow. If left unpruned, its thorns make a very effective barrier.
The Washington Hawthorn produces abundant fruit which are eaten by birds & mammals. It is an important nectar plant for bees.
First noted scientifically in 1883, the tree received its name from its point of origin when introduced to Pennsylvania from Washington, becoming known as the "Washington Thorn" because of its prominent thorns.

Conifer List Montezuma cypress (Taxodium mucronatum). Cypress in name only; a closer relative of redwoods and sequoias. Native to Guatemala, Mexico and south Texas, this turns into a giant with a vaulting trunk and graceful, weeping boughs. Given moderate water, it can reach 40 feet in 15 years. Growth slows with age.
Learning About Pine Cones The name "pine cone" is improper for any other conifer cones. While collecting pine cones in the park for my crafts, I observed which pine tree they came from and the best time to collect them. I saw that some of the pine cones had seeds inside, but I was intrigued that some of them weren't woody. A quick search on the internet showed me the difference between the cones. The cone is an organ which contains the reproductive structures of the Phinophyta (conifers) division. Its botanical name strobilus comes from some of the species' geometrical cone form of this organ. The woody cones, as we know it, are the female cones which produce seeds.
Male cones (microstrobilus or pollen cone) are herbaceous and produce pollen. They are structurally the same on all conifers, with small differences from species to species. At first glance, they all seemed like cones to me, but now I know what they are. They are growing on a central axis, from modified leaves (microsporophyllis) under which the pollen sacs (microsporangia) are growing. The male cones are usually colored differently from the female cones, in yellow, red, purple, green or grey. I had these male cones in a a potpourri on my table and I didn't know what they were. They are dry, but still have the male cone form. comes from some of the species' geometrical cone form of this organ. The woody cones, as we know it, are the female cones which produce seeds.
The female cones (megastrobilus, ovulate or seed cone) contain ovules which become seeds when fertilized by pollen. The female cones are different from species to species, making possible the identification of many conifer species. The plates of a cone are called scales and they differ from species to species. Female cones have two different types of scales: the bract scales, derived from a modified leaf and the seeds scales, derived from a modified branchlet.
First appear the bract scales, and after pollination the seeds scales develop to enclose and protect the seeds. The cones close during the fertilization, then re-open to let the seeds go. Cones can open and close many times as long as the cone is on the branch, even if all the seeds are gone.
On most conifer species, male and female cones grow on the same tree; usually the female are on the upper part, while the male cones are on the lower branches. The explanation of this particular arrangement of the cones in a conifer tree is very interesting: the male cones grow on the lower branches so they can pollenize the female cones from another tree and not from the same. The wind takes the pollen up in the air, usually over other trees nearby. This way the species will remain strong and live on.
The conifer families have different forms of female cones:
Pinaceae, which have "archetypal" cones. This means that their scales are overlapping each other like fish scales. The scales are spirally arranged in fibonacci number ratios.
Araucariaceae, is a very ancient conifer family with three genera: Agathis, Araucaria and Wollemia which have globose type of cones.
Araucaria genus is different from the other two because the male and female cones are found on different trees, like the Araucaria araucana also called the Monkey tail tree.
Podocarpaceae is a member of the Antarctic flora and has very different type of cones, berry-like.
Cupressaceae, the Cypress family with the genera cypresses, arborvitae, junipers and redwoods have the bract and seed scales fully fused. The cones are usually small and spherical, like those of Nootka cypress.
From the cypress family is also the Bald cypress - Taxodium distichum - also called Swamp cypress, one of the few decidous conifer species, meaning it looses its leaves in the fall.
When I was living in Bucharest I saw many Bald cypresses in the park, along the lake. One fall I took pictures of their beautiful and interesting cones.
[The leaves of this tree are similar to those of the Yew tree and thus the similarity in the scientific names between Taxodium and Taxus. These same leaves also help distinguish this tree from true cypress trees that have a similar "cone" but a very different leaf.] Sciadopityaceae has only one genera endemic to Japan, with cones similar to those in the Cupressaceae family, only larger.
Taxaceae, the yew family, and Cephalotaxaceae have cones with a few scales which develop into fleshy arils.
I have two conifer trees from the Pinaceae family in my garden, a Norway spruce - Picea abies and a Colorado blue spruce - Picea pungens glauca. Last month I saw many buds forming on their twigs. The first time I saw them last year I thought they were cones. They looked like very small cones, but later in spring I saw new growth sprouting from those "cones". Now I know that they are only buds which will open up in spring. Norway spruce and the Colorado blue spruce will make cones after they reach maturity, after 20 years of growing.
Introduction to Cycads, the ultimate Jurassic landscape and/or potted plants This is a brief article about one of the most prehistoric of all landscape plants for warmer climates.. There are few better plants for investment value as well- cycads will only go up in value with age and size. And, thankfully, beauty also increases with value as well.
The most common cycad, and the one most people have heard of, is the Sago Palm. Cycas revoluta is NOT a palm despite what its common name suggests, but is a classic cycad, with it’s palm-like trunk and simple, pinnate leaves. Cycads are non-flowering plants that are actually more closely related to conifers than to palms or any other flowering plants. They reproduce by making cones and seeds. All cycads are dioecious, which means they are either male or female, and never both.
As mentioned above, cycads are typically ‘palm-shaped’: symmetrical plants with fronds arising from the tops of their stems (also called a caudex, trunk or base), similar to how palms or many ferns grow. The frond, or leaf, is made up of a petiole, which arises from the stem and has no leaflets on it, a rachis, which is what the petiole is called further from the stem where the leaflets come off either side (like a palm or fern leaf) and, of course, the leaflets themselves, which are the ‘leaf-shaped’ parts that come off either side of the rachis (with remarkable regularity in cycads).
A petiole or rachis is unbranched in all but a few cycads- they have simple pinnate (‘feather-shaped’) leaves. These leaves/fronds are typically somewhat ‘plastic’ or leathery in consistency, which is one of the characteristics that makes cycads unique. These leaves come in various shades of green to blue-green and some are even a pale blue. Some have smooth, simple, spineless leaflets, while some are known for their incredibly sharp, multispined, twisted leaflets. Some cycads can be quite hazardous to handle for this reason.
As a cycad ages, it gets taller from the top of the stem. As is also the case with palms or tree ferns, once a cycad has matured to a certain thickness, it will not get any thicker with age, and all growth is directed either up, or into new suckers/pups that arise from ether the root stock, or along the caudex itself. All the energy of the plant is in this caudex (and sometimes the roots), so this is the business part of the plant. Cycads are basically caudiciform succulents. Leaves, and sometimes roots, are expendable. Cutting all the leaves off a cycad rarely affects it in a negative way. But damage the caudex and the plant is often lost.
Cycads have various root types- some have huge, succulent roots- these varieties usually live in very arid climates. In many of these plants, the caudex itself is also underground and only the leaves are visible except in very old plants. Most cycads have one large carrot-like root, and smaller, more ‘normal’ roots.
There is another kind of root that is somewhat unique to cycads- the collaroid roots, which exist just above or below the surface of established plants, and whose function is to help fix nitrogen via bacteria living in those roots. A cycad with a lot of these collaroid roots is usually a well established and ‘happy’ plant.
Cycads live in nature all over the tropical world, from Central and South America, to Africa, Asia and Australia. A few Zamias are native the ‘tropical US’. No cycads are from colder areas of the world, though some Asian species do live in relatively cool environments. In many of their native lands, some species are extremely endangered and, in a few cases, already extinct. Collecting cycads from the wild is something that is not only frowned upon these days, but is usually unlawful and closely regulated. Saying that, it still happens, thanks to the huge amounts of money some of these plants go for, so probably many of the species that exist today will be extinct in the near future.
Not all cycads need the same care, but in general, most are NOT fond very cold climates, with only a few taking freezing temps at all. One of the reasons Sago Palms are such popular cycads is they tolerate a moderate degree of frost/ freezing climates, but even these have their limits.
Cycads are succulents basically and many can be grown similarly to how one grows most succulents. Most tolerate some dryness and appreciate being grown in very well draining soil- most do not tolerate being grown in clay or other poorly draining soils.
If in a warm climate with the proper soil, most cycads prefer to be watered regularly, and though many are drought tolerant, they tend to perform much better and grow faster if given water often and fertilized regularly as well.
Planting or transplanting cycads is relatively easy. Root damage will usually occur, as cycad roots are not that sturdy. However, care should be taken not to damage the main, carrot-like root(s) too badly, as injury to this root will allow fungal infections to develop, and sometimes overtake the plant. Still, if this root is badly damaged, often the plant will survive, but will need to be kept dry (do not replant immediately) until the injury ‘cures’ over. Rooting hormone and/or antifungal powders/creams on these injuries can be beneficial. It is best not to water a cycad after transplanting it, as that will also allow fungus and opportunity to invade. Best to wait a week or so (less for very small plants of course) to allow root damage to heal and roots to be able to uptake water again.
Most cycads like sun, though some species/genera are not that tolerant of full sun in very hot climates
Cycads need to be trimmed as the older, senescent leaves die. This can be hazardous if you have a spiny species, so use gloves as/if needed. If for some reason the leaves are damaged, but not dead, they still can be cut off without damage to the plant itself. If you trim a living leaf, which is OK if need be, a clearish ‘goo’ may ooze from the cut end. This is the cycads way of curing itself- sort of like a built in liquid bandage system. Seeing this ooze arise from the caudex is not usually a good sign- it indicates there is some damage of the caudex at that site, or deeper within (trauma, insect damage etc.). But do not clean it off- most cycads can heal their wounds well. Just look for the inciting cause if possible.
One of the reasons cycads are such popular collector plants is they are slow growing. Most can live your entire life in a pot, though almost all will grow faster and better in the ground. Many species will make 1-3 leaf flushes a year… some less often, some more. But very little height is gained in a single new set of leaves, so overall height is a very slowly increasing situation. This makes all but the oldest, hugest plants manageable for the average collector to keep and maintain. With proper care many cycads can live for many hundreds of years… some very old plants in the wild may be thousands of years old. Dying of old age is something much more likely to happen to the grower than to the plant itself.
Cycas revoluta, the Sago Palm, is an easy plant to grow from offsets, and it also is one of the easier species to pollinate as well. See discussion above about rerooting cycads.
Cycads are, in general, toxic, inedible plants. However, many have historically been used for food by native peoples, who know either what the safe parts of the plants are, or how to properly prepare them. It is best to just assume all parts are toxic, and to keep that in mind when you have pets and/or small children. Though most pets will not eat a cycad, some dogs will eat the leaves or fruits and some species are deadly toxic. And cattle will happily graze on some cycads and succumb to their toxic properties as well. Please keep this in mind when selecting what species to get and where to plant them.
Now, truth be told, mulberries aren’t nearly as known as other berries, and to many who do know them, they have a speckled reputation. The berries are known to stain driveways. The trees are known to reproduce like weeds. The trees are also infamous for attracting insects and creating pollen. Even so, for permaculture practitioners, the hard-nosed mulberry is often amongst the top trees to include in a garden.
Mulberries, being tall and sprawling trees, are great for providing a shady spot. They’ll grow up quickly and cover a corner of the yard, creating a strategic spot for some hammock-with-a-book time. What’s more is that they are deciduous, loosing their leaves in the winter, so they produce shade in the summer, when it’s needed, and let the sun in during the cooler season, when more warmth is needed.
For some, mulberries aren’t the most beloved. They are sometimes known to be invasive, multiplying when birds deposit their seeds everywhere, and the berries can stain surfaces. However, put in the right place, put in a new garden, the trees grow fast, provide a lot of food, intoxicate the surrounding wildlife, and generally allow for some early success with food cultivation.
Trees can form bonds like an old couple and look after each other A forester and scientist have been studying communication between trees for decades; their incredible observations can be seen in the new documentary, 'Intelligent Trees.'
Trees have feelings. They can feel pain, but can also have emotions, such as fear.
Trees like to stand close together and cuddle.
There is in fact friendship among trees.
These are just a few of the wonderful observations made by tree whisperer, Peter Wohlleben, the German forester extraordinaire and best-selling author of "The Hidden Life of Trees."
When I wrote about Wohlleben earlier this year (Trees in the forest are social beings), I was floored by how his work resonated with tree-loving me. Here was an established forester – with a proven track record of improving forest health and loads of scientific research under his belt – swooning about trees as if they were people. “These trees are friends. You see how the thick branches point away from each other? That’s so they don’t block their buddy’s light.” And while some biologists might kvetch about this anthropomorphizing, Wohlleben counters: “I use a very human language. Scientific language removes all the emotion, and people don’t understand it anymore. When I say, ‘Trees suckle their children,’ everyone knows immediately what I mean.”
Now Wohlleben has teamed up with forest ecologist Suzanne Simard from the University of British Columbia, Canada in a new documentary called "Intelligent Trees." We have also sung the praises of Simard around here; her decades of research and findings about how trees communicate is as groundbreaking as it is profound … and beautiful. Together, Wohlleben and Simard are a tree dream team.
In the film they explore the various ways in which trees communicate, noting that:
Trees are so much more than rows of wood waiting to be turned into furniture, buildings or firewood. They are more than organisms producing oxygen or cleaning the air for us. They are individual beings that have feelings, know friendship have a common language and look after each other.
As Wohlleben says in the trailer below, "There is in fact friendship among trees. They can form bonds like an old couple, where one looks after the other.”
And on that note, I'm pretty sure there is in fact friendship among trees and humans, too.
You can stream the film at Vimeo On Demand, there is a web series of shorter highlights available as well. And see more about the film at the website, Intelligent Trees.
20 random reasons to really love trees There are approximately 2 million reasons to love trees ... but we'll start with these.
It’s no secret that I go nuts for the trees. I talk to them, I pet them … the Lorax is my spirit animal! So it’s no surprise that Arbor Day, generally observed on the last Friday of April, holds a special place in my heart. What could be better than a day dedicated to observing the importance of trees and better yet, to planting new ones?
It’s funny because I often think about how vital it is to be good stewards to trees – but when I muse upon how critical they are for us, I think that maybe I have it all wrong. What if it’s the trees who have been acting as good stewards to us all along?
Arbor Day in the United States was officially designated in Nebraska in 1872 – pioneers moving to the treeless plains realized they needed trees for things like fruit, windbreaks, fuel, building materials and shade. Essentially, food and shelter and the necessities for survival. So who’s taking care of whom here? We need trees, but do trees need us? They need us not to cut them down indiscriminately, for sure, but really they seem to be doing most of the work in this relationship.
Consider the following:
1. Trees work hard to right our wrongs
According to the U.S. Forest Service, the trees around the world removed about one-third of fossil fuel emissions annually between 1990 to 2007.
2. They help keep our houses clean
A study from Lancaster University found that trees by the road reduced the presence of airborne particulate matter (pollution from cars) inside nearby homes by 50 percent.
3. They ease the workday
Office workers who can gaze upon trees from their windows report less stress and more satisfaction, according to a study from Chungbuk University, South Korea.
4. Trees feed us, they give us pie!
Trees provide food for people and wildlife beyond what we likely imagine. A single apple tree alone can produce up to 15-20 bushels of fruit per year. Apples, pie, important!
5. They provide shelter and support
Three hundred million people across the globe live in forests and 1.6 billion depend on them for their livelihoods, according to the World Wildlife Fund. Forests also provide habitat for a mind-boggling array of plants and creatures, many of which we don't even know about.
6. They show us how to age gracefully
Seriously, talk about respecting your elders. The world’s oldest tree is an ancient bristlecone pine named Methuselah that lives at 10,000 feet above sea level in the Inyo National Forest, California. Methuselah is as old as Stonehenge and older than the Egyptian pyramids.
7. Trees keep cities cool
Trees lower urban temperatures by up to 10°F by shading and releasing water vapor into the air through their stress-soothing leaves.
8. They are giant humidifiers (kind of)
In a single day, one large tree can lift up to 100 gallons of water out of the ground and discharge it into the air.
9. They keep buildings comfortable
Of course shade trees produce shade; a lot. Strategically placed trees can cut down air conditioning needs by 30 percent and can save up to 50 percent in energy required for heating.
10. Trees are social beings
"They can count, learn and remember; nurse sick neighbors; warn each other of danger by sending electrical signals across a fungal network known as the 'Wood Wide Web' – and, for reasons unknown, keep the ancient stumps of long-felled companions alive for centuries by feeding them a sugar solution through their roots." That's not me being woo-woo, but a very poetic tree expert. Read more here: Trees are social beings
11. They devour carbon dioxide
Biology 101 tells us that trees absorb carbon dioxide (CO2), removing and storing the carbon while releasing the oxygen back into the air – but the amount is remarkable. In a single year, an acre of mature trees absorbs the amount of CO2 equivalent to a car driven 26,000 miles.
12. Likewise, they give us breath
Four people can get a day’s worth of oxygen from one large tree.
13. And water In the United States, watersheds protected by forests provide water to more than 180 million people.
14. Trees fight crime
A study by the University of Vermont and U.S. Forest Service found that in Baltimore alone, a 10 percent increase in tree canopy corresponded to a 12 percent drop in crime.
15. They fight grime
In outdoor spaces with trees, there is less graffiti, vandalism and littering in comparison to place without greenery, says a study from the University of Washington.
16. They give us something to look up to, literally
The tallest living tree is a towering 379.1-foot coast redwood (Sequoia sempervirens) in California's Redwood National Park in 2006. Called Hyperion (above), it miraculously survives on a hillside, rather than the more-typical alluvial flat, with 96 percent of the surrounding area having been logged of its original coast redwood growth.
17. They pay us back
For each dollar spent on planting a tree in the city, they pay us back by up to five times in terms of cleaner air, lower energy costs, improved water quality and stormwater control and increased property values.
18. They're ersatz war heroes
Sure, we’ve long had a national anthem and bird – and we’ll always have apple pie and baseball – but what about a national tree? We got one in 2004, and it’s the oak. Oak trees have long been prized for their attributes as well as their place in U.S. history, from Abraham Lincoln’s use of the Salt River Ford Oak as a marker in crossing a river near Homer, Illinois, to Andrew Jackson taking shelter under Louisiana’s Sunnybrook Oaks on his way to the Battle of New Orleans, notes the Arbor Day Foundation. "In the annals of military history, 'Old Ironsides,' the USS Constitution, took its nickname from the strength of its live oak hull, famous for repelling British cannonballs." See how well trees take care of us?
19. They are unassuming in their vastness
There are more than 23,000 different kinds of trees in the world; altogether, there are three trillion trees on the planet. Yet they just humbly stand by, working hard and never making too much of a fuss.
20. Trees keep us young and rich
And when all else fails, there's this: They may keep us young and rich! Research found that people who live on streets with high tree density are less likely to report a number of health complaints; and specifically, trees improve health perception in ways comparable to an increase in annual personal income of $10,000 or being seven years younger. You can never be too rich or too thin, and you can never live among too many trees. End of story.

Texans across the Lone Star State are invited to celebrate Arbor Day Nov. 4.
Arbor Day is a holiday for trees - it is the perfect day to plant trees and to celebrate all the ways that trees enrich our lives, communities and landscapes.
In Texas, the official state Arbor Day celebration is held in a different host city each year on the first Friday in November. This year, the city of Nacogdoches will host the Texas Arbor Day celebration in the Millard's Crossing Historic Village.
The celebration, is aptly themed Leaving a Legacy, as Nacogdoches, celebrating a Tricentennial this year, is recognized as the Oldest Town in Texas. Festivities will feature a ceremony, educational activities, tree plantings, giveaways and homage to historic and champion trees. Events are free and open to the public.
For those unable to attend the state celebration, Texas A&M Forest Service invites you to celebrate Arbor Day in your own ways, in your own communities.
"The idea is for everyone in Texas to take one day - the same day - to truly appreciate trees and plant one," said Paul Johnson Texas A&M Forest Service urban and community forestry program coordinator. "Planting a tree leaves a legacy for future generations while beautifying the spaces where we live, work and play today."
Texas A&M Forest Service is making it easy for anyone, anywhere to participate in Arbor Day. We've provided tips online to help you create a memorable Arbor Day in your own community, and fun, educational activities for schools, groups and families to get outdoors and learn more about trees.

Later, I was able to discover its identity & learned it is a very attractive deciduous tree to 20’ tall & wide with a beautiful form & pretty, dark green, pinnate leaves. In Spring it bears masses of huge panicles (at least 24” long) of very sweetly fragrant, lavender, 5-petaled star flowers.
The stout trunk has bark similar to an oak & the wood is very hard & beautifully grained (it’s related to Mahogany). This is one beautiful, tough, pest free & drought tolerant tree, perfectly suited to our climate. An excellent street tree, too. Plant carefully in southern States as it has become a bit weedy there.
Requires full sun, low water, zones 7b-11.
Melia azedarach commonly known by many names, including chinaberry tree, Pride of India, bead-tree, Cape lilac, syringa berrytree, Persian lilac, and Indian lilac, is a species of deciduous tree in the mahogany family, Meliaceae, that is native to Indomalaya and Australasia.
Texas Invasives Deciduous tree to 50 feet (15 m) in height and 2 feet (60 cm) in diameter, much branched with multiple boles, lacy dark-green leaves having a musky odor, and clusters of lavender flowers in spring yielding persistent, poisonous yellow berries.
Ecological Threat: Chinaberry outcompetes native vegetation due to its high relative resistance to insects and pathogens. Its leaf litter raises soil pH, thus altering soil conditions for native plants and seed germination.
Chinaberry is a very fast growing tree that reaches 18 - 24 feet in height in 4 - 5 years. May reach 50 - 60 feet in total height.
Biology & Spread: Reproduces on-site primarily from root sprouts, and over longer distances via bird-dispersed seeds. Reproductively mature when it reaches the size of a shrub. Flowers in the spring, fruits in the summer. Fruit remain on the tree past leaf fall.
History: Introduced in the mid-1800s from Asia. Widely planted as a traditional ornamental around homesites. Extracts potentially useful for natural pesticides.
Chinaberry Tree Information Native to Pakistan, India, Southeast Asia and Australia, chinaberry tree information tells us it was introduced as an ornamental specimen to the United Sates in 1930 and for a period of time became the darling of landscapers in the southern United States. Today, the chinaberry tree is considered something of a pest due to its reseeding propensity and easy naturalization.
Growing chinaberry trees (Melia azedarach) have a dense spreading habitat attaining heights of between 30 to 50 feet tall and hardy in USDA zones 7-11. Growing chinaberry trees are prized as shade trees in their native habitat and bear pale purple tube-like blooms with a heavenly scent much like southern magnolia trees. They are found in fields, prairies, along roadsides and at the edge of wooded areas.
The resulting fruit, marble sized drupes, are light yellow gradually becoming wrinkled and white over the course of the winter months. These berries are toxic to humans when eaten in quantity but the juicy pulp is enjoyed by many bird varieties, often resulting in rather “drunken” behavior.
Chinaberry trees are resilient specimens and can be quite messy from the dropping berries and leaves. They spread easily, if allowed, and, as such, are classified as an invasive tree in the southeastern United States. This prolific mahogany member grows rapidly but has a short life span.
Chinaberry Uses: As mentioned above, the chinaberry is a valuable shade tree in its endemic regions due to its large, spreading canopy. Chinaberry uses in the southeastern regions of the United States have been used for just this attribute and were commonly added to the home landscape prior to the 1980’s.
The most commonly planted variety is the Texas umbrella tree with a slightly longer life span than other chinaberries and a lovely, distinct rounded shape. ... a narcotic; refer to the toxicity of the fruit and the tipsy, gorging birds.
Today, the chinaberry is still sold in nurseries but is less likely to be utilized in landscapes. Not only is it a threat to the natural ecosystem by its encroaching habit, but its messy and, more importantly, shallow root systems tend to clog drains and damage septic systems. Growing chinaberry trees also have weak limbs too, which break easily during severe weather, creating yet another mess.
If, after reading all the above information, you decide you just must have a specimen of the chinaberry in your garden, purchase a disease free certified plant at the nursery.
Chinaberry plant care is not complex once the tree is established. Plant the tree in full sun in most any soil type within the USDA zones 7-11. The tree should be watered regularly, although it will tolerate some drought and needs no irrigation through the winter months.
Prune your chinaberry tree to remove root and shoot suckers and maintain the umbrella-like canopy.
I am in zone 8. I am growing Satsuma mandarin, lemon, and grapefruit. They are in containers and during this recent cold snap I brought them into the greenhouse for a couple of days. I have put them in the garage before. So, I would be cautious about growing in the ground in zone 8. There are a few people downtown where it's protected that are growing mandarins outside and they are doing great! I bought mine from Four Winds. they have a hardiness chart on their web site.
i don't know if i live in zone 8A or just zone 8, but oranges do well over here. it does get really cold some winters and the frosts seem to damage the oranges depending on how bad the temperature is. I know people have orange trees everywhere around here and despite a little die back on the new growth, the trees seem to be fine. We had about 4 days that droped down around 26and 27 and alot of plants died , but i havn't seen any dead citrus trees. My neighbors on both sides have citrus and they are fine, one of my neighbors tree, still has a bunch of oranges on it. They sure are good!
Satsuma is the best tasting cold hardy citrus, seedless too.
Growing Citrus Trees A lot of people worry that citrus trees will not be easy to grow or will take forever to bear fruit. Put that thought behind you because neither of those assumptions is necessarily true. Even if you live where winter can toss a frost or two your way you can still enjoy fresh, organic citrus grown at home. For those who live in frigid climates, you too can succeed at growing citrus quite easily.
One of the biggest problems anyone has with homegrown citrus, such as lemons, oranges and clementine trees, is that they don’t purchase super vigorous, healthy young trees to begin with. No matter what type of plants you try to grow, it will be much harder to do so easily if you purchase weak, immature or sickly plants in the first place. Start with a plant that has a well developed root system and not a twig in a dixie cup.
The next step to success is to decide if you live in a location that the citrus trees can be planted outside in your garden soil or is best grown in a pot. If frost and below freezing temperatures is a possibility, you will want to container grow your chemical free citrus so you can winter it indoors. No matter where you will be growing your new lifetime supply of delicious Vitamin C, your young tree will need very good drainage and lots of sunshine. So, if container growing for wintering indoors, it is necessary to plant these types of fruit trees only in pots that have drainage holes in the bottom.
Selecting Your Outdoor Planting Site: Obviously, most homeowners don’t have lots of choices as to where you will plant your citrus trees. Except for some very southern regions, if you live north of zone 8, you should be prepared to container grow your citrus. In zone 8, it is best to plant citrus trees on the south or southeast side of your home. This provides added protection from northwestern cold fronts. Planting your new citrus tree close to your home’s walls is also advisable as the heat the structure gives off will work to give it added warmth during such bouts of chillier than normal temperatures.
Do be sure and place the trunk of the citrus plants a minimum of 6-8 feet away from walls, fences and paved surfaces like drives and sidewalks. Also, space your citrus trees 6-8 feet apart for ease of picking and maintenance. Naturally, should you have a septic system, choose your planting location away from it and your drain field. In the city, you won’t want to place such a deep rooted plant near or over sewer lines as they can cause you a nightmare of clogged sewer lines as your new trees mature.
You should never plant citrus trees beneath other trees, as they need full sunlight for ultimate growth and fruiting.
The Right Soil Requirements for Citrus Trees: All citrus trees require deeply draining soil. This means runoff water leaves the area and the drainage beneath the surface is excellent and will not saturate the root system. Finding out what kind of soil you have to a depth that your new citrus will grow can be as simple as taking stock of what the other trees in your yard look like. Healthy shade and ornamental trees in your landscaping is a good sign that your soil should be great for growing citrus trees.
You can also plant your new citrus orchard in raised beds to create better drainage below the surface. Your soil pH should be in the range of 6-8 and not be high in salt, as citrus won’t be happy about dwelling in the wrong conditions. You can get your soil pH tested easily with pH test kits from your local garden center.
Planting Your New Citrus Trees in the Yard: Unlike many types of nursery container grown plants, citrus trees will take a long time to root past the potting medium and into your ground soil. To help them spread their roots faster and improve initial new growth rates, remove the exterior of the potting soil just as you are ready to slip the tree in its installation hole. Don’t take all of it off, that would be harmful – just the outer half inch or so to allow the roots to be surrounded with your ground soil. This is very simple to do by washing it off with the hose immediately before sinking your young citrus tree in its new real soil home.
You want to cut a 4 ft. circle out of your lawn as the start of your planting hole. Discard the grassy top layer and dig your hole half again wider than each citrus tree’s root ball. When planting citrus you will want to ‘plant it high’, meaning you want the top of the finished planting surface to be crowned 1 inch higher than the lawn. This creates your surface run-off of water, and will be a great assistance to your tree in wet weather.
You won’t need to do a lot of amending with good soil, so don’t worry about adding compost and peat unless your soil is not good quality for drainage. With your tree set in the planting hole, fill around it half way to the top and thoroughly saturate the back fill soil. This helps it to settle around the roots of your new citrus tree’s ball. Finish filling the hole and tamp your loose soil into place lightly. Cover the roots with no more than 1 inch of ground soil to seal the potting soil from direct air contact. Soilless medium used in production nurseries is design to air dry too rapidly for home growing, blocking the air with a layer of soil stops you from having rapid drying problems.
To let your citrus tree be able to have deep root watering, build a water retention ring around the perimeter of your planting circle that is 5 – 6 inches tall and 6 – 8 inches thick. When completed, your watering ring should be slightly wider than the removed circle of lawn for your planting hole. Don’t skimp, should you be short on soil left from the planting, buy some from your local garden center or borrow it from your garden. Fill your new citrus tree’s watering basin with water, touching up any sinking spots in the planting hole that may settle after this first deep root watering.
Mulching: Do not mulch over 3 inches deep and never put mulch any closer to the trunk of citrus trees than 12-24”. Nature didn’t create mulch, man did. Mulch can cause fungus issues with citrus plants.
Watering: When freshly planted, citrus trees need a deep, thorough watering two to three times the first week and one to two times per week for the next few weeks, depending upon soil type, rainfall and the time of year. Once this adjustment and establishment period is over, water them deeply whenever the soil begins to get dry an inch or so below the surface. Simply fill the water ring each time. Within about four, perhaps six months, your watering reservoir will erode away. Don’t worry about rebuilding it, by this time your new citrus trees will be established enough that you can use a soaker hose to supply that deep root moisture as the water in your soil level drops.
Nutrition: Don’t worry about fertilizing your new citrus trees when planting. Once your plants begin putting on new growth you will want to begin your fertilization schedule of once a month from February through October. Citrus trees are hungry plants and excellent performance will come from applying citrus fertilizer on a timely basis. You will also have good results with palm fertilizer, as they have almost identical requirements. Organic products to look for are Citrus-tone from Espoma and Dr. Earth Organic 9 Fruit Tree Fertilizer.
Scatter the prescribed amount of organic fertilizer on the ground at least a foot away from the trunk and promptly water it in thoroughly. Notice in the chart below that young citrus will need an increasing amount of fertilizer applied in the first few years you have it in your yard.
Citrus Tree Fertilizing: February – October
Year 1 monthly application 1 cup
Year 2 monthly application 2 cups
Year 3 monthly application 3 cups
Year 3 monthly application 4 cups
Container grown citrus needs to be feed more frequently than trees planted in outdoor ground soil.
Pruning: Grown in outdoor soil, these fruit trees will have a naturally full and pleasant shape. Citrus trees grown indoors can become leggy and getting them to be fuller is done by partially cutting back the growth to increase branching and density. Should the canopy of your indoor citrus get way too big for the containerized roots, some falling leaves and fine twig dieback can happen. This is corrected by pruning your citrus plant’s canopy back heavily.
Which Fruit Trees Grow Best in Zone 8? Fruit trees grow best within an optimal range of temperatures and are injured by excessive heat or cold. Heat and cold tolerance varies greatly between fruit tree species. The U.S. Department of Agriculture plant hardiness zone map is helpful in assisting the home gardener in selecting trees that are appropriate for their location. Gardeners in USDA zone 8 can select from a diverse array of easy-to-grow fruit trees that add bold color, flowers, fragrance and visual interest to the landscape.
Cleveland pear trees (Pyrus calleryana 'Cleveland Select') are well suited to cultivation in zones 5 though 8. The tree exhibits clusters of fragrant, white flowers in spring and resists damage from wind, ice and snow. The fast-growing tree quickly matures to a height of 30 to 40 feet tall and does well in small garden spaces. Cleveland pear trees do best in organically rich, well-drained soil and prefer a full-sun location. In autumn, the leaves turn a deep scarlet red. Kieffer pear (Pyrus communis x P. pyrifolia) is a heat-tolerant pear tree that flourishes in zones 4 though 9. The hardy fruit tree grows from 15 to 30 feet tall with a 12- to 20-foot spread and produces delicious, gold-colored fruit. It is important to plant at least two Kieffer pear trees to assure pollination.
The Kwanzan cherry tree (Prunus 'Kwanzan') flourishes in zones 5 through 9. In spring, the fast-growing tree displays clouds of fragrant, deep pink-colored flowers. Kwanzan cherry trees grow in almost any soil condition and reach a mature size of 30 to 40 feet tall and wide.
Dwarf Gala apple trees (Malus 'Gala') grow well in zones 5 though 8. One of the most popular varieties of apple tree, the Gala apple resists bruising and softening. Flavorful and delicious, Gala apples are a tasty addition to the home orchard. Gala apple trees reach a mature height of 10 to 15 feet and achieve a width of 8 to 10 feet. They prefer well-drained, nutrient-rich soil and a full-sun location. Stayman Winesap apple (Malus x domestica) grows best in zones 5 to 8. The hardy tree produces an abundance of pink flowers and tart red apples.
Early golden apricot (Prunus armeniaca) is an attractive landscape tree that exhibits pink or white flowers followed by sweet and plump apricots. The fast-growing apricot tree is well suited to cultivation in zones 5 though 8. Moorpark apricot (Prunus armeniaca) grows best in zones 4 though 8. The fast-growing tree produces fruit in July and August.
Fruit and Nut Producing Trees for USDA Hardiness Zone 8B Below is a list of trees that will grow in zone 8b (USDA Hardiness 15 to 20 degrees Fahrenheit, Austin, TX to Gainesville, FL). I've put together this list for those interested in beginning to research an orchard or fruit tree grove. I've included general characteristics about the tree, harvest time, height, and applicable hardiness zones. Additionally, I've included Latin names for all varieties to make future research easier. Please note with many of the rootstock varieties, researching by Latin name versus commercial name may be more difficult.

Clementine Facts and Care Tips Every December you probably notice Christmas trees and lights going up everywhere, all over your neighborhood and on the inside of every store. You also probably notice citrus hitting the shelves of super markets at low prices. This is because winter is citrus season, so there’s an abundance of fresh oranges, lemons, and limes. One of the most popular seasonal citrus fruits is the Clementine, so this article includes facts and helpful care tips all about it!
1. Clementine Trees are hybrids between Mandarin Orange Trees and Sweet Orange Trees.
2. Some sources say that a French monk by the name of Marie-Clement Rodier created the hybrid tree. Other sources say that the Clementine Tree existed in China years before Rodier made his hybrid. Either way they made it to America in 1909.
Christmas Fruit and Spice3. Although Tangerines and Clementines are both linked to Mandarins, Clementines taste very sweet while tangerines taste sour.
4. Tangerines have seeds, but Clementines are seedless. Sometimes Clementines are referred to as ‘Seedless Tangerines.’ Due to their ripening season from November to January they’re also known as ‘Christmas Oranges’.
5. You can recognize a Clementine by its small shape. They’re wider than they are tall and have smooth glossy skin.
6. The skin on Clementines is extremely easy to peel. Also, Clementines can very easily be broken apart into 8 – 14 different sections.
7. The nutrients found in Clementines includes fiber, calcium, potassium, and vitamin C.
1. Clementine Trees flourish in full to partial sunlight. Even though they prefer full sun, they can tolerate shade. 2. Sandy soil is best for Clementine Trees, but they will adapt to your natural soil. To make your soil sandier mix in sand or a fine potting mix. Just make sure that your soil is well draining.
Don’t over water your tree. Check on your soil every few days, and only give your trees water when your soil is dry to the touch down to about 2 inches below the surface.
4. In the early spring and early fall give your trees some citrus fertilizer that’s high in acidity. However, wait until your tree has had one year of growth before you fertilize it.
5. Clementine Trees produce white flowers in the spring before their fruit begins to grow. Your fruit will be ripe and ready to be harvested towards mid-November when its skin fully turns orange. If you see green on the skin or around the stem then your Clementines aren’t ready to be harvested yet.
6. Clementine Trees are recommended for growing zones 8 through 11, and are cold hardy down to about 20 degrees Fahrenheit.
7. If you live in an area that gets colder than 20 degrees, plant your Clementines in containers and bring them indoors when it gets cold. These trees do extremely well in pots, and indoors. Just place them by a large sunny window and watch them take off.
Yard Fanatic I live in Zone 8; the same climate as Portland, Oregon. What I am trying to do here in Austin would make the Oregon-resident Sheryl scoff. After all, I am the same gardener who stopped raising roses because they couldn’t fend for themselves. And now I’m stringing lights, creating plastic domes, and sobbing in the garage over some trees?
CITRUS TREES It isn’t hard to grow a lifetime supply of free organic citrus. Citrus trees don’t have lots of pest issues and they are highly resistant to disease. Even if you live in a climate with very cold winters, you can still enjoy fresh, organic citrus grown at home.
Your first step is to determine if you live in a location where your citrus trees can be planted outside in your yard. For most of the country, your new citrus plants will best be grown in a container. If you live above zone 8b, or if frost is even a remote possibility, you will want to grow your citrus trees in a container and bring them indoors during the winter. Your young tree will need excellent drainage and lots of sunshine no matter where you plant it. So, only select pots that have drainage holes in the bottom for colder regional growing success.
Unless you live on a large piece of land, most homeowners will have limited planting choices. For homeowners in zone 8, be safe and plant your citrus trees along the southern or southeast side of your home. This offers extra protection from northwestern winter cold fronts. Plant your new citrus tree 6-8 feet away from the walls of your house, so the heat from your home will work to add warmth during those surprise cold snaps. Maintain the same distance from garages, driveways, walks and fences, as well as spacing citrus trees away from each other. You’ll have an easier time picking your tree’s sweet fruit and caring for your new citrus orchard this way.
Don’t get the idea that you’re protecting your citrus plants from cold by planting them under big trees. You won’t have an abundant harvest without full sun. Also, be sure you don’t plant the trees over or close to sewer lines or a septic field.
The best soil for citrus trees is deeply draining with good top runoff. This allows water to drain away from the deep root system. If you are not sure how well your subsoil drains, the other trees in your yard bear clues. Are your shade and spring flowering trees all very healthy and producing vigorous growth? If so, you most likely have the level of drainage already in place to succeed in growing citrus plants. If other trees in your yard aren’t looking healthy, you will want to grow your citrus trees in raised beds.
As with any other plant, the level of pH in the soil will present you with problems if it is too low or too high. For citrus trees, you need 6-8 pH for them to grow well. Citrus also is not tolerant of high soil salinity, which can be present near saltwater shores. Discovering the pH is easily accomplished with a soil tester purchased from local stores.
Start your planting process by digging a hole 3 feet wide in your yard. Save all soil and get rid of the grass and its roots on the top layer. Dig your hole twice as wide as the root ball. Loosen the soil beneath where your tree will sit, which will help your roots grow easier.
It is up to you to create the surface runoff for the tree. This is done by crowning the final soil surface an inch higher than the surrounding soil level in the grass.
Coaxing your new citrus tree to spread its roots out into the soil is easily done. Rinse the soilless medium away from the roots, about ½ inch deep on all sides of the root ball. This is not done until the moment you are going to place your new fruit tree in the planting hole. Do not remove more than ½ inch of soil medium from your tree’s roots, because this could damage your tree. What this does is allow the roots to be surrounded with your ground soil. Do this by simply washing it off with the hose immediately before planting your tree.
There isn’t any need to add compost to the existing soil. It will not improve drainage because your tree’s roots will grow deeply into the ground. Check the depth of your hole before rinsing away potting soil with the hose. Then, place your tree in the hole. Fill the hole halfway up with dirt, and evenly around the roots. Add some water, and then finish filling the hole with soil. Pat the surface of your finished planting area to lightly compact the soil.
During the first few months your tree is in the ground, it needs deep root watering. This is easily accomplished by building a water reservoir, with soil walls, around the perimeter or your tree circle. Form the dirt walls 6 inches high and 6 inches thick. Your finished deep water reservoir should be solid. At this point, your new citrus tree needs a big drink quickly. With reservoir walls properly in place, fill the watering resevoir with water. Any areas that sank when the water has drained need additional soil. Maintaining surface runoff is not possible with depressions in the soil surface.
Caring for Newly Planted Citrus Trees
No matter what kind of shrubs, trees or plants are in your landscaping – never put down mulch that exceeds 3 inches deep. Mulching around your new citrus tree is not a good idea, since it can sometimes cause fungus problems. If you simply must have that aesthetic appeal, keep all mulch two feet away from the trunk.
Following the initial deep root watering at planting time, new citrus trees need a deep watering 2 – 3 times during the first week in the ground. For the next few weeks, fill the watering reservoir 1 – 2 times a week. Watering will vary according to your type of soil, how much rain you’ve had that week, and what time of year you planted the new tree. This watering schedule is an establishment practice. After the first month to six weeks, you will only need to provide deep watering when your ground soil dries to a depth of an 2 inches.
By the end of six months or less, the soil walls of your water reservoir will have eroded away. You don’t need to replace them, since they only help your tree get established.
At planting time, don’t fertilize citrus trees. Instead, wait until new growth appears. Then you should begin a feeding schedule of once a month from February through October. For excellent fruit and growth production, you’ll want to use quality organic citrus fertilizer. Look for organic fertilizers formulated perfectly for citrus trees, such as Citrus-tone from Espoma and Dr. Earth Organic 9 Fruit Tree Fertilizer. If you cannot find either of those, you can use palm fertilizer, as they have almost identical requirements.
Scatter the measured organic fertilizer on the ground at least a foot away from the trunk – thoroughly water the fertilizer. Young citrus trees have an annual increased need of fertilization because their root system is increasing over this time span. Bear in mind that if you are growing your trees in containers, they will need fertilizing more often than a tree planted in the ground.
Growing Citrus Trees in Containers
Selecting the Right Pot
To succeed at growing live plants, it doesn’t matter if the container is made of plastic, clay, metal or wood – it must have adequate bottom drainage holes. Don’t worry about potted soil escaping. Just buy a water tray and place a fine meshed screen or weed barrier cloth on the bottom before planting. The layer of porous material allows water to leave while keeping the potting soil in your container.
Consider the mobility you will need when selecting your citrus tree’s container. Whatever you choose will weigh far more filled with your tree, potting soil and drainage gravel. Clay and ceramic containers are a lot heavier than plastic. Resin and wood containers will be far easier to move around in the house and into the outdoors during summer.
Don’t start off with a small tree in a huge pot, thinking it will be economical. Too much soilless medium surrounding the citrus plant’s roots will bring you high moisture health issues.
Correct Citrus Tree Potting Method
With your weed barrier or screen in place at the bottom of your pot, lay in an inch or two of pea gravel for proper drainage. Next, you will need to get your potting medium right. Not all commercial mixes found at your store will be okay. Most of these products are predominantly sphagnum peat, which is highly acidic and inappropriate for the longevity of many plants… especially citrus. Do not use ordinary top soil in any container planting; it will quickly kill the contents of your pot.
Select an easy to obtain soilless potting medium that contains either vermiculite or perlite. Blend in some cedar shavings with your potting medium for even distribution. Fill the planter partially and you are ready to inspect the citrus tree’s root system. Any plant grown in a container will become somewhat root bound, a condition that should be dealt with whenever you transfer them to a larger container. You can easily correct the situation by carefully spreading the larger roots, allowing them to grow outward instead of continuing to grow in the same tight circle. Be sure to loosen the remaining outer roots to help them escape from their previously cramped condition.
Situate the tree in your partially filled container. Maintain the same surface level of potting soil as it was growing in the original nursery pot. Complete the process of filling around your root ball. Be sure to leave watering depth, from the rim of the pot to the soil surface, of ¼ to ½ inch. Don’t fertilize until you see new growth appearing, just as is done in outdoor growing of citrus trees. After watering your newly potted tree thoroughly, you have finished your planting.
Most fruit crops do best in full sun, but some will do well in partial shade. As with anything that flowers, the more hours of sun each day, the heavier the blooming will be. Without flowers, fruit cannot form. This controls how big your harvest will be at the end of your citrus tree’s cycle. Over the winter, you will want to house your tree in front of the sunniest window you have. Once all threat of frost is over, you can move your citrus tree outdoors into a spot where it will get at least 8 hours of direct sun every day.
Any plant kept indoors over the cold season must be slowly adjusted to the intense light. Consider how you experience the instant introduction to brilliant light after being in the dark for a long time. Prepare citrus trees for full sun placement by alternating shade and sun exposure, adding an hour every few days. Begin with an hour on day one. To prevent shock, start the process 2 weeks before the full time move. The same is true of preparing citrus trees for being moved back indoors for winter. Whichever direction you are headed with light acclimation, you’ll want to slowly change from direct sun exposure or part shade exposure.
Tropical and subtropical fruit trees cannot tolerate freezing temperatures. Some will suffer “die back” only on the youngest twigs, while others will die back to the ground. Being without insulation, and completely exposed to frigid temperatures, is something only very cold hardy plants can endure.
Just moving them inside is not total protection from icy drafts. Always place your potted citrus tree where cold blasts from opening exterior doors and the heating system vent cannot hit them.
You must pay attention to the cooling night temperatures. It would be best to start the process when nighttime temperatures begin dipping into the high 40s. Also keep watch for unexpected frost. You can always move the tree inside for the night, and go back to light acclimation, after the frost has melted. The time this will happen is all dependent on how far north you live.
Water Right for Best Results
The most common reason people fail at growing plants in containers is either not enough or too much water, whether caused by a lack of drainage or watering too often. You should only water as needed, especially with citrus trees. Clay and wood containers will dry faster than plastic, metal and ceramic because air can enter the walls of these pots. This is why you should never use real soil with a tree in a container.
Always check your potting soil for dryness watering; you want the surface to be very dry to the touch. The light consistency of soilless medium makes it float away when a rush of heavy water presents itself, so be sure to slowly add the water to your pot, and avoid exposing the citrus tree’s roots to the air. Empty the pot’s water tray if it starts filling up. Good drainage isn’t happening if the bottom drainage holes are submerged in deep water. Cooler temperatures always slow the growth and water needs of citrus trees.
While the roots prefer to stay on the dry side, citrus leaves love humidity. Indoor Citrus will do best if misted daily especially when you are running your heat during cooler months. You can also use a humidifier or fill your pot’s saucer with rocks and add water; place your plant on the rocks ensuring the bottom of the pot is above the water line.
Fertilizing Container Grown Citrus Trees
An excellent, balanced fertilizer schedule is highly important to your success in receiving an abundant harvest from vigorous container-grown citrus trees. Over fertilization can result in too much foliage growth, poor fruit production and dieback. Use organic fertilizer blended for the needs of citrus trees, like Citrus-tone or Dr. Earth’s Organic 9, and follow the directions on the label for container-grown plants. When the mature foliage on your citrus trees is deep, rich green, you know you have the correct fertilizer application.
Citrus trees don’t do well in saline soils. If a white crust forms on the potting soil surface, it is likely due to excess fertilizing and/or your water has large amounts of soluble salts. This situation should be corrected by washing the trapped salts out of the container by slowly running water through the container for several minutes. This will carry the excess salts down through the potting medium to exit via the drainage holes.
Citrus trees grown outdoors are always naturally dense with a lovely full shape. When growing citrus plants indoors, the weaker light in winter can cause them to become leggy. Pruning back the tree’s canopy partially will induce more branching to assist you in producing a fuller tree and more fruit. You can also control the amount of space the citrus tree starts to take up in the house as it matures by pruning. When the top of your citrus tree have outgrown the available root space in the container, it is normal to see falling leaves and young twig die-back.
CTG plant of week: Satsuma ‘Orange Frost’ Thanks to Larry Stein from the Texas A&M AgriLife Extension Service for this picture of a new cold hardy satsuma orange cultivar ‘Orange Frost.’
This great addition to our satsuma mandarin choices is a brand new Texas Superstar plant that our AgriLife researchers have been trialing for a few years now.
‘Orange Frost’ mandarin is a hybrid cross between a very seedy but cold hardy, Changsha tangerine and a very high quality Satsuma.
The fruit is very sweet, easy to peel, and only has one or two seeds per fruit.
More importantly, the tree has more cold hardiness than satsuma, so once established, it will tolerate more cold, meaning that it can be planted in the landscape a bit further north than other citrus.
‘Orange Frost’ has proven to be reliably hardy in zone 8, which includes Central Texas. But for the first few years, when the tree is young and getting established, you’ll need to protect it during the winter.
‘Orange Frost’ needs full-day sun to perform and fruit well. And it gets only 8 to 10 feet tall, making the fruit easy to harvest. But it can also get 8 to 10 feet wide, so be sure to give it plenty of space to spread out. Be sure that the soil has good drainage. And don’t plant until after ALL danger of frost has passed. For good growth and a bountiful harvest, water regularly and fertilize monthly during the growing season.
As with other citrus trees, ‘Orange Frost’ satsuma is evergreen, and if it DOES get bitten by the cold, the good news is that it isn’t grafted, meaning that it will come back true if it has to regrow from the roots. This tree will also work well in containers.

SAWS: No-Fail Fruit Trees for San Antonio It is best bet is to select fruit trees that are suited for our warm winters. Consider these:
For peaches, 'June Gold,' Tex Royal' and 'La Feliciana' do best; 'Elberta' will not survive here.
For apples, try 'Dorset Golden' and 'Anna;' forget about 'Red Delicious.'
The best pear varieties are 'Warren' and 'Kieffer;' 'Bartlett' pears are highly susceptible to fire blight.
The 'Methley' plum is the best choice for San Antonio.
Full sun and good drainage are musts for all fruit trees whether they're grown in native soil or raised beds.
FRUITS FOR SAN ANTONIO The toughest, most adapted fruits include Oriental persimmon, pomegranate, blackberries, and figs. Plums, pears, and grapes are in an intermediate category, and apples, strawberries, and peaches are the most difficult to grow. Do not bother to try and grow raspberries, cherries, or blueberries; they do not survive in our alkaline soil and/or weather conditions. Apricots make a pretty tree but are not productive in this area.
Oriental persimmon make a wonderful lawn tree. The trees are small and open with large leaves that can be colorful in the autumn. The fruit on the tree often looks like Christmas bulbs—colorful, well spaced, and showy. Persimmon is astringent; it will make you pucker up if it is eaten before it is mushy ripe. The exception is Fuyu. Another variety to consider is Haichiya. The birds, raccoons, and opossum will eat the fruit you do not harvest. Oriental persimmon can be grown in our native soil. It will survive without irrigation but will produce more fruit if it is watered regularly in the summer.
Figs are also easy to grow in San Antonio. Select from Celeste and Texas Everbearing. They all have a closed eye (keeps insects out). Brown Turkey has an open eye but is still a good choice. Once established, figs can survive without irrigation but will not produce much fruit. Mulch heavily (4 to 8 inches) over the root system and irrigate regularly for maximum production.
Blackberries are so productive they can be overwhelming during their short season. They also can take over your garden because of their growth rate and thorns. If you have blackberries, expect to be ruthless in rogueing out the canes that spread from the original planting. The old wood must also be removed after harvest in April or May to make room for the new canes. Consider Brazos, Kiowa, or Rosborough for huge yields. Thornless selections such as Arapaho and Navajo are not as productive but are easier to manage.
Pomegranate is an interesting fruit. The tart flesh surrounds the seeds inside an apple-shaped case with a crown. The fruit is attractive on the shrub but the blooms are spectacular. They are glow-in-the-dark red-orange in late spring. The plant is one of the few deer-proof fruits. It makes a large dense deciduous shrub. Wonderful is the recommended variety. Pomegranate is a good xeriscape plant.
