The River Birch also adapts well to wet and dry planting sites. This fast and easy to grow River Birch Tree reaches a height of feet with a width of feet at its maturity. The River Birch is a very popular tree in most states due to its adaptable nature allowing it to grow in most growing zones.
How To Prune A River Birch Tree River Birch don't generally require pruning, but, if needed, prune when they are dormant in winter or early spring to remove any dead, dying, or crowded branches, or to maintain shape. How To Plant A River Birch Plant in a hole twice as wide as the rootball and cover the top of the roots with soil mix. Pick a spot with full sun exposure in grow zones and water twice a week until established.
Azaleas and hydrangeas look great planted around the base of this tree. Before planting your River Birch be sure you have the right location and conditions for this tree to thrive. Spring and Fall are ideal times to plant. However, if you avoid extreme temperatures you can plant your tree almost any time of the year.
Full Sun is the ideal choice for the River Birch, but as far as soil, this tree is adaptable. This tree tolerates wet soil, but is also drought tolerant once established. Water deeply twice weekly for the first 3 months after planting. This helps the tree's roots establish properly.
After establishing, your tree will only need water during dry periods. The outer peeling trunk can be grayish-white to gray-orange, while the inner color is light reddish-brown to tan-brown. Discovered by John D. The exfoliating trunk and branches expose cinnamon-colored bark.

Requires partial shade in the southeast. Originated as a seedling of unknown parentage that was discovered by John D. The pendulous form of Summer Cascade weeping river birch provides fall and winter interest. It grows 30 to 40 feet tall with a 20 to foot spread and develops a broadly pyramidal to oval crown.
The dark green leaves turn yellow-gold in the fall. Resistant to leaf spots and is cold- and drought-tolerant. Selected by Carl Whitcomb, Ph. Note: Chemical control of diseases and insects on large trees is usually not feasible since adequate coverage of the foliage with a pesticide cannot be achieved.

To propagate through cuttings, in early spring as new growth is beginning take 6- to 8-inch long cuttings from new wood from near the tips of the stems, where new wood joins old wood.
Make sure the cutting has several leaf nodes, then remove all but the top one or two leaves. Dip the cut end in rooting hormone, then plant the cutting in a sandy potting mix. Place the potted cutting in a bright outdoor location and keep the soil moist until new leaves begin to sprout. Continue to grow it in the pot until the tree is large enough to plant in the garden.
The failure rate for propagating from cuttings can be high, so it is best to take at least five cuttings to ensure that at least one develops roots and grows into a sapling.

The bark on the trunk varies a lot among individual plants, ranging in color from silvery gray-brown to pinkish-brown when young, but always with darker, narrow, longitudinal lenticels.
It is either scaly or peels off in curly papery sheets or flakes of gray, brown, salmon, peach, orange, and lavender. More mature trunks are rough and irregularly dark gray with deep fissures that may have some pink color in the crevices. Branches on older trees tend to be a smooth and shiny gray with much darker bark on the trunk. The very slender new twigs are a red-brown color, while thin branches are cinnamon-colored with many lenticels.
Older branches may also be exfoliating — typically in a gray-brown-light orange mixture on the species form but in shades of cream, light orange, and lavender on selected varieties.
The branches are not brittle, so are not prone to wind or ice damage. Twig and branch die-back is not uncommon and these dead parts tend to be messy as they shed readily. The branches of river birch are smooth with many lenticels L , but the trunk and older branches are scaly or peeling C and R , with variable color.
The leaves are diamond-shaped. The leaves are typical of a birch — alternate, diamond-shaped, with a doubly serrated margin. They are a shiny, medium green color on the upper surface and a slightly paler, more silvery color on the underside.
In the fall leaves may turn a bright golden yellow but often the fall color is dull and brownish-yellow. This species is a larval host plant for mourning cloak butterflies. River birch in bloom L with the male catkins most noticeable R. River birch is monoecious separate male and female flowers on the same plant with flowers arranged in catkins. The brownish male catkins occur in clusters at the ends of the twigs.
They form in fall and mature to release pollen the following spring. Because the flowers are wind pollinated, the male catkins produce abundant pollen a significant cause of seasonal allergies in the spring.
