Ohio’s state tree and the symbol for Ohio State University’s intercollegiate athletics, Ohio buckeye trees (Aesculus glabra) are the best known of the 13 species of buckeyes. Other members of the genus include medium to large trees such as the horse chestnut (A. hippocastanum) and large shrubs like the red buckeye (A. pavia). Read on for information about buckeye tree planting and some interesting buckeye tree facts.
Buckeye Tree Facts Buckeye leaves are made up of five leaflets that are arranged like spread fingers on a hand. They are bright green when they emerge and darken as they age. The flowers, which are arranged in long panicles, bloom in spring. Green, leathery fruit replace the flowers in summer. Buckeyes are one of the first trees to leaf out in spring, and also the first to drop their foliage in fall. Most of the trees in North America called “chestnuts” are actually horse chestnuts or buckeyes. A fungal blight wiped out most of the true chestnuts between 1900 and 1940 and very few specimens survived. The nuts from buckeyes and horse chestnuts are poisonous to humans.
How to Plant a Buckeye Tree Plant buckeye trees in spring or fall. They grow well in full sun or partial shade and adapt to most any soil, but they don’t like an extremely dry environment. Dig the hole deep enough to accommodate the root ball and at least twice as wide. When you set the tree in the hole, lay a yardstick or flat tool handle across the hole to make sure the soil line on the tree is even with the surrounding soil. Trees that are buried too deep are susceptible to rot. Backfill the hole with unamended soil. There is no need to fertilize or add soil amendments until the following spring.
Water deeply and in the absence of rain, following up with weekly waterings until the tree is established and beginning to grow. A 2- to 3-inch layer of mulch around the tree will help keep the soil evenly moist. Pull the mulch back a few inches from the trunk to discourage rot. The main reason you don’t see more buckeyes as a yard tree is the litter they create. From dead flowers to leaves to the leathery and sometimes spiny fruit, it seems that something is always falling from the trees. Most property owners prefer to grow buckeyes in woodland settings and out-of-the-way areas.

Red buckeye trees are relatively easy to care for, medium sized trees or shrubs that produce showy red flowers in the spring. They are a great choice for large, easy decoration along borders. Keep reading to learn more about red buckeye tree care and red buckeye tree growth.
Red Buckeye Tree Growth What is a red buckeye tree? Red buckeye trees (Aesculus pavia) are North American natives from southern Missouri. They grow in USDA zones 4 through 8. For several weeks in the spring the trees produce bright red panicles of tube-shaped flowers. The flowers have no real scent, but they are striking in color and very attractive to hummingbirds. Once the flowers fade, they are replaced by dry, round, orange fruits. These fruits are toxic to both animals and humans. Keep this in mind when choosing a planting location. The trees produce a lot of fruit, and when it drops it can be a nuisance to clean up and a real danger to pets and children. Red buckeye trees are deciduous, but their leaves aren’t showy in the fall. They barely change color and drop relatively early.
Red Buckeye Tree Care Planting a red buckeye tree is relatively easy. The trees can be grown very successfully from seed and should bloom within three years. Red buckeye tree growth is best in rich soil that is well drained but moist. The trees do not handle drought well. They will grow in both shade and sun, but they’ll stay smaller and won’t fill out as nicely in the shade. In sun, the trees tend to grow between 15 and 20 feet in height, though they will sometimes reach as high as 35 feet.

Here’s a species of tree you might not see growing wild in your area. Kurrajong bottle trees (Brachychiton populneus) are hardy evergreens from Australia with bottle-shaped trunks that the tree uses for water storage. The trees are also called lacebark Kurrajongs. This is because the bark of the young trees stretch over time, and the old bark forms lacy patterns on the new bark beneath. Growing a Kurrajong bottle tree is not difficult since the species is tolerant of most soils. Read on for more information about bottle tree care.
Kurrajong Tree Info The Australian bottle tree is a pretty specimen with a rounded canopy. It rises to some 50 feet high and wide, offering an evergreen canopy of shiny, lance-shaped or lobed leaves several inches long. It is fairly common to see leaves with three lobes or even five lobes, and Kurrajong bottle trees do not have thorns. The bell-shaped flowers are even more attractive when they arrive in early spring. They are creamy white, or off-white, and decorated with pink or red dots. In time, the flowers of the Australian bottle tree develop into edible seeds that grow encased in pods. The pods themselves appear in clusters in a star pattern. The seeds are hairy but, otherwise, look something like corn kernels. These are used as food by the Australia aborigines.
Bottle Tree Care Growing a Kurrajong bottle tree is a rapid business, since this little tree gets to its mature height and breadth in no time. The principal growing requirement of the Australian bottle tree is sunshine; it cannot grow in shade. In most ways the tree is undemanding. It accepts almost any type of well-drained soil in U.S. Department of Agriculture plant hardiness zones 8 through 11, including clay, sand and loam. It grows in dry soil or moist soil, and tolerates both acidic and alkaline soil.
However, if you are planting an Australian bottle tree, plant it in direct sun in a moderately fertile soil for best results. Avoid wet soil or shady areas. Kurrajong bottle trees are not demanding about irrigation either. Bottle tree care involves providing moderate amounts of water in dry weather. The trunks of Kurrajong bottle trees store water, when it is available.

Blackthorn (Prunus spinosa) is a berry producing tree native to Great Britain and throughout most of Europe, from Scandinavia south and east to the Mediterranean, Siberia and Iran. With such an extensive habitat, there must be some innovative uses for blackthorn berries and other interesting tidbits of information about blackthorn plants. Let’s read on to find out.
Information about Blackthorn Plants Blackthorns are small, deciduous trees also referred to as ‘sloe.’ They grow in scrubs, thickets and woodlands in the wild. In the landscape, hedges are the most common use for growing blackthorn trees. A growing blackthorn tree is spiny and densely limbed. It has smooth, dark brown bark with straight side shoots that become thorned. The leaves are wrinkled, serrated ovals that are pointed at the tip and tapered at the base. They may live for up to 100 years. Blackthorn trees are hermaphrodites, having both male and female reproductive parts. The flowers appear before the tree leafs out in March and April and are then pollinated by insects. The results are blue-black fruit. Birds enjoy eating the fruit, but the question is, are blackthorn berries edible for human consumption?
Uses for Blackthorn Berry Trees Blackthorn trees are extremely wildlife friendly. They provide food and nesting space for a variety of birds with protection from prey due to the spiny branches. They are also a great source of nectar and pollen for bees in the spring and provide food for caterpillars on their journey to becoming butterflies and moths. As mentioned, the trees make a terrific impenetrable hedge with an enclosure of painful spike laden interwoven branches. Blackthorn wood is also traditionally used for making the Irish shillelaghs or walking sticks. As to the berries, the birds eat them, but are blackthorn berries edible for humans? I wouldn’t recommend it. While a small amount of raw berry will probably have little effect, the berries do contain hydrogen cyanide, which in larger doses may definitely have toxic effect. However, the berries are processed commercially into sloe gin as well as in wine making and preserves.
Prunus spinosa Care Very little is needed in the way of care for Prunus spinosa. It grows well in a variety of soil types from sun to partial sun exposures. It is, however, susceptible to several fungal diseases which can cause blossom wilt and, therefore, affect fruit production.

Native to northern climates, paper birch trees are lovely additions to rural landscapes. Their narrow canopy produces dappled shade that makes it possible to grow these trees in a sea of groundcover plants such as wintergreen and barberry, and you can even grow grass under them. Unfortunately, paper birches don’t fare well in the city where they struggle to survive in the face of pollution, heat and dry conditions. Although they love cool climates, the branches break easily on windy days, especially when weighted down with snow and ice. Despite these drawbacks, they are well worth growing for their beautiful bark that shines against a dark background.
What Is a Paper Birch Tree? Paper birch trees (Betula papyriferia), also called canoe birches, are native to moist stream banks and lakesides in Northeastern United States and Canada. They have a single trunk, but nurseries like to grow them in clumps of three and call them “clumping birches.” The lowest branches are just a few feet off the ground, and in fall the foliage turns a blazing shade of yellow. Growing paper birch trees means you’ll always have something interesting to look at in the landscape.
Paper Birch Tree Facts Paper birch trees grow as much as 60 feet tall and 35 feet wide, adding as much as 2 feet per year in USDA plant hardiness zones 2 to 6 or 7 where winters are cold. The tree’s most striking feature is its peeling white bark, which is highlighted with streaks of pink and black. In spring, it produces hanging clusters of catkins that are very attractive when in bloom. Most specimens have bright-colored fall foliage. Paper birch trees are a larval host for luna moth caterpillars. They also attract a number of birds, including yellow bellied sap suckers, black-capped chickadees, tree sparrows and pine siskins.
Here are a few uses of paper birch in the landscape: Grow them in groups in moist beds and borders. Their thin canopy lets you grow other plants beneath them. Use paper birches to transition gradually from woods to open ground. Although the roots are shallow, they don’t usually rise above the surface of the soil, so you can use them as lawn or roadside trees. How to Care for a Paper Birch Tree Paper birches transplant easily with little shock. Plant them in a location with full sun and moist but well-drained soil. The trees adapt to most types of soil as long as it is cool in summer. It prefers long winters and mild summers. Paper birches are susceptible to a number of insects, including the destructive bronze birch borers. If you live in an area where these insects are a problem, try planting a resistant cultivar such as ‘Snowy.’
You can also help the tree resist birch borers by fertilizing annually in spring and using organic mulch. It’s best not to prune a paper birch unless absolutely necessary because it attracts insects and the tree bleeds copious amounts of sap when cut.

A weeping silver birch is a graceful beauty. Bright white bark and long, downward growing shoots at the ends of the branches create an effect unmatched by other landscape trees. Find out more about this lovely tree and weeping silver birch care in this article.
What are Weeping Silver Brich Trees? Weeping silver birch (Betula pendula) is a European species that is well suited to North American locations with mild summers and cold winters. It isn’t a low-maintenance tree, but it well worth the time you put into it. Weeping silver birch growing conditions include full sun and well-drained, moist soil. The soil should never dry out. A thick layer of mulch around the base of the tree will help hold moisture in. Weeping silver birch trees grow best in areas where summer temperatures rarely exceed 75 degrees Fahrenheit (25 C.) and where the roots are covered with snow for most of the winter.
Care of Weeping Silver Birch An important part of the care of weeping silver birch trees is keeping the soil evenly moist. If the soil in the area isn’t naturally moist, install drip irrigation under the mulch. The tree is susceptible to fungal diseases for which there is no cure, but you may be able to keep them at bay by pruning out diseased twigs and branches. Prune in late winter before the tree breaks dormancy. Pruning cuts bleed an abundance of sap if you wait until spring. Cut back to healthy wood. The cut will stimulate growth from the side shoots and nodes below it, so it’s best to cut just above a node or side shoot.
If the long shoots make landscaping tasks, such as mowing, difficult, you can cut them back to the desired length. Always mow so that any sticks or debris caught by the mower blades will be thrown away from the tree instead of toward it to prevent trunk injuries. Injuries create entry points for insects and disease. Plant a weeping silver birch in an area where it is in scale with the rest of the landscape and where it has room to spread to its mature size. The tree will grow 40 to 50 feet tall, and will look awkward in a small yard. The canopy will spread 25 to 30 feet, and it should not be crowded by structures or other trees.

Birch trees are highly desirable landscape trees because of their beautiful bark and graceful foliage. Unfortunately, they aren’t known for their long lifespan. You can improve their chances by pruning birch trees properly, and taking advantage of the best time to prune birch trees.
Reasons for Cutting Back Birch Trees There are several reasons for cutting back birch trees: Remove dead, diseased and injured branches for the health of the tree. Branches that rub together offer entry points for insects and disease, so remove one of them. Branches that grow nearly straight up have weak attachments to the trunk. Take them down while they are small to prevent them from breaking off later on. Remove a branch that is too close to another branch. This is best done when the tree is young. Remove branches that are too close to the ground to make landscaping easier and allow comfortable use of the shade. You can remove any branch that detracts from the overall appearance of the tree.
When to Prune Birch Trees Most landscapers prune trees just before they break dormancy in late winter or early spring, but this timing doesn’t work for birch trees. They bleed a heavy flow of sap if pruned when awakening from their winter rest, so the best time to prune birch trees is late summer or early autumn. When you prune at the proper time, you not only avoid sap flows, but you also avoid the egg laying season for most insects that infest pruning wounds. These insects cause unsightly damage, and they can spread serious diseases. Birch tree borers are tree killers, and you should reduce the risk of attack by cutting after their early summer flying season whenever possible.
How to Prune a Birch Tree There are several steps in pruning a birch tree. Take care of the easy stuff first by removing side shoots and suckers as necessary. Next, decide which branches to remove. Be as conservative as possible. Removing more than twenty-five percent of the canopy of a tree at one time weakens it and may be fatal. Never top a tree. Remove branches less than two inches in diameter as close as possible to the collar, or thickened area where the branch attaches to the trunk. Use one quick cut with long-handled pruners to remove the branch, and then clean the pruning tool with a ten percent bleach solution or a household disinfectant before moving to another branch.
Larger branches are taken down with three cuts. Here’s the procedure: The Undercut – From the trunk of the tree, measure 18 inches out along the branch. At the 18-inch mark, make a cut one-third to one-half of the way through the branch beginning at the underside and working in an upward direction. This cut prevents the falling branch from stripping bark and wood from the tree as it falls. The Main Cut – Measure an inch or two out from the undercut and cut the branch from the top downward. Cut all the way through as smoothly as possible. Tidying Up – The 18- to 20-inch stub that remains is an unnecessary eyesore, and can cause disease if it dies back. It will not regrow, so cut it off flush with the collar.

The river birch is a popular tree for river banks and wet parts of the garden. Its attractive bark is especially striking in the winter when the rest of the tree is bare. Keep reading to learn more river birch tree facts, such as river birch tree care and effectively using river birch trees in the landscape of your home.
River Birch Tree Facts River birch trees (Betula nigra) are hardy in USDA zones 4 through 9. They are more heat tolerant than most of their birch relatives, making them a good choice in many parts of the southern U.S. They grow naturally in wet environments along river and stream banks, so they are used to very moist soil. They will tolerate soil that is acidic, neutral, or alkaline, as well as well or poorly drained. Though they do best in moist conditions, they tolerate drier soil better than other birch trees do. These trees prefer full sun but will tolerate partial shade. They tend to grow between 40 and 70 feet in height.
Growing River Birch Trees in the Landscape In nature, you will most likely find a river birch tree growing near water. Because of its affinity for wet, heavy soil, planting a river birch tree can fill in spaces where nothing else seems to grow. If you have water on your property, consider lining it with river birch trees. If you don’t, planting a river birch tree or two in your yard will make for an attractive specimen and shade tree. Surround the tree with heavy mulch to help keep the roots wet and cool.
River birch trees can be grown direct from seed or planted as saplings. When seeds or saplings are starting out, it’s important to control weed competition nearby either with weed fabric or select herbicidal spraying.

If you tell your friends or neighbors that you are growing bee bee trees, you may get lots of questions. What is a bee bee tree? Do bees like bee bee tree plant flowers? Is bee bee tree invasive? Read on for answers to all these questions plus tips of growing bee bee trees.
What is a Bee Bee Tree? The bee bee tree, also known as Korean evodia (Evodia daniellii syn. Tetradium daniellii), is not a well-known ornamental, but it should be. The tree is small, generally not much taller than 25 feet, and its dark green leaves provide light shade beneath. The bark is smooth, like beech tree bark. The species is dioecious, so there are male trees and female trees. In late spring or early summer, female bee bee trees grow a gorgeous display of fragrant, flat-topped flower clusters that last a long time. Bees love the flowers, and beekeepers love the bee bee tree plant’s long blooming season. On the female bee bee tree plants, the flowers ultimately give way to fruits in the form of capsules. Inside are purple, fleshy seeds.
Bee Bee Tree Care If you are planning on growing bee bee trees, you’ll be glad to know that bee bee tree care is not difficult if you select an appropriate location. The tree thrives in moist, fertile soil that drains well, and does best in full sun. Like most trees, bee bee tree plants require regular irrigation for the first year after planting. This is an especially important aspect of bee bee tree care when the weather is dry. After establishment, the mature trees can tolerate some seasonal dryness. You’ll find that bee bee trees do not suffer from many diseases, nor are they attacked by insect pests. In fact, even deer tend not browse bee bee tree plants.
Is Bee Bee Tree Invasive? The bee bee tree fruit produces many seeds. These seeds can propagate the species far and wide when spread by hungry birds, even naturalizing in the wild. Scientists do not know very much about this tree’s impact on the environment. Given its invasive possibilities in some circumstances, it is called a “watch list species.”

The large, white flowers of the baobab tree dangle from the branches on long stems. Huge, crinkled petals and a big cluster of stamen give baobab tree flowers an exotic, powder puff appearance. Find out more about baobabs and their unusual flowers in this article.
About African Baobab Trees Native to the African Savannah, baobabs are best suited to warm climates. The trees are also grown in Australia and sometimes in large, open estates and parks in Florida and parts of the Caribbean. The tree’s overall appearance is unusual. The trunk, which can be 30 feet in diameter, contains a soft wood that is often attacked by a fungus and hollows it out. Once hollow, the tree can be used as a meeting place or dwelling. The interior of the tree has even been used as a jail in Australia. Baobabs can live for thousands of years.
The branches are short, thick and twisted. African folklore holds that the unusual branch structure is the result of the tree’s constant complaining that it didn’t have many of the attractive features of other trees. The devil yanked the tree out of the ground and shoved it back in top first with its tangled roots exposed. Additionally, its strange and eerie appearance made the tree ideal for its starring role as the Tree of Life in the Disney film Lion King. Baobab flower blooming is another story altogether.
Flowers of Baobab Tree You can think of an African baobab tree (Adansonia digitata) as a self-indulgent plant, with flowering patterns that suit itself, but not the desires of people. For one thing, baobab flowers are stinky. This, combined with their tendency to open only at night, make baobab flowers difficult for humans to enjoy. On the other hand, bats find baobab flower blooming cycles a perfect match for their lifestyle. These night-feeding mammals are attracted by the malodorous fragrance, and use this feature to find the African baobab trees so they can feed on the nectar produced by the flowers. In exchange for this nutritious treat, the bats serve the trees by pollinating the flowers.
The flowers of the baobab tree are followed by large, gourd-like fruit that is covered with gray fur. The fruit’s appearance is said to resemble dead rats hanging by their tails. This has given rise to the nickname “dead rat tree.” The tree is also known as the “tree of life” for its nutritional benefits. People, as well as many animals, enjoy the starchy pulp, which tastes like gingerbread.
