River Birch Tree

The River Birch is a sturdy tree with a delicate appearance. It grows quickly, looks beautiful in all seasons and helps to reduce erosion with its roots. If you want a native Floridian tree to add shade or aesthetic appeal to your landscaping, the River Birch may be just what you're looking for.

Appearance

Like many types of Birch tree, the River Birch has pale, paper-thin bark that peels away from the trunk. As it peels away, the outer bark reveals a salmon-pink color, ranging to red-brown, that adds visual interest all year round. Paired with the tree's slender form and small leaves, this will make for an elegant, attractive addition to your patio or front yard.

The River Birch is unusual among Floridian trees in that it is deciduous, meaning that it will lose its leaves in autumn. This means you'll get to enjoy a full range of color over the course of the year. 

In early spring, look for the fresh, bright green color of baby leaves as they first come out. In late spring and early summer, you may spot dangling green or brown catkins - the River Birch tree's fruit. The seeds are a popular food for nuthatches, chickadees, titmice and other native birds.

As fall begins, you'll be able to enjoy the seasonal color change as your River Birch's leaves turn yellow or orange and gradually shed from the tree. Then, during the winter, you can enjoy the elegant silhouette of the leafless tree. As the spring season comes round again, you'll see the buds as leaves begin to form.

Because it loses its leaves, the River Birch has the advantage of being an excellent shade tree during the summer while allowing more light to filter through during the winter. This deciduous tree is therefore a good choice for use near windows, porches or patios.

Its constantly changing yet ever-beautiful appearance makes the River Birch an attractive feature in rural and urban settings.

Growing a River Birch

River Birch trees grow quickly compared with many other large trees, typically gaining one to two feet in height per year. The trunk remains slender as they grow. A mature River Birch can get as tall as 90 feet but this beautiful tree more commonly grows to 40-50 feet tall. River Birch trees have a modest spread of 20-30 feet wide.

Its speedy growth is one of the features that makes this Birch species a particularly suitable tree for landscape use. Start with a young tree and it will take only a few years for you to be enjoying the shade on your patio or watching the bright green leaves tremble in a morning breeze. Children will enjoy seeing the difference in height as this tree grows quickly enough for them to notice.

Although a River Birch will begin its life with a single trunk, as it matures, it will often form multiple trunks with an irregular crown. This produces a natural effect that is sure to add charm to your landscape design.

The River Birch has a shallow root system, which makes it easy to transplant young trees. However, it can mean that the roots interfere with your lawn if you have grass growing right up to the base of the tree. Not only can the tree compete with the grass roots for water, but products such as fertilizer or herbicide, applied to the turf, can come into contact with the tree.

The easiest solution to this potential difficulty is to situate your River Birch in a circle of mulch, which will protect the tree's roots, keep soil moisture locked in, and ensure that the grass doesn't have too much competition.

River Birch Tree Care

River Birches are hardy in Zones 4-9. They can tolerate a range of soil types, including sand, clay soils, or loam. They do best in moist soil that is also well-drained and prefer slight acidity. This means they are well suited to Florida's environment, as our sandy soil generally drains well and is often slightly acidic.

The River Birch is also well suited to Florida's hot climate. It thrives in full sun, although it can also tolerate some shade. During much of the year, Florida's characteristic heavy rain creates the moist conditions that a River Birch requires. Like many species of plants that thrive in Florida, though, the River Birch may require extra watering during hot, dry spells.

River Birches can often be found growing on stream banks, where their roots help to control soil erosion. The same can apply in your own landscape; erosion can be a problem with sandy soil, so planting River Birch trees could help to prevent that. This tree will even tolerate moderate flooding, and its flexible branches make high winds less problematic than for some sturdier trees.

If your River Birch is spreading in an undesirable direction, or growing too many drooping branches, feel free to prune it in early fall after it has shed its leaves.

The quick growth rate of the River Birch does also mean that it has a shorter lifespan than many slower-growing trees. Most River Birches live around 30-40 years.

If you have been looking for a low-maintenance ornamental tree that will thrive in Florida's climate and soil conditions, and will add charm and beauty to your landscape design, the River Birch may well be the tree for you.
