How to Maintain a River Birch Tree
The River Birch tree is a popular ornamental tree in the northeastern United States and Canada. The plant is known for its attractiveness, cold and drought-tolerant nature, and ability to harvest water. These traits make it an excellent choice for homeowners and landscapers alike. But despite its popularity, it's not a long-lived tree, so the best way to maintain it is to keep it healthy and well-maintained.
Water-harvesting
Water-harvesting on River Birch trees can be accomplished in a number of ways. One way is through seedlings. The seeds of river birch trees should be planted in pots of about six inches, using a mixture of half sand and half loam. Once the seeds sprout, they should be placed in a warm, but sheltered, location. During the day, these seedlings should be kept in the shade or on a heating mat. At night, the temperature should be kept around 70 degrees F. The soil should be kept moist but not too moist. The river birch seedlings can then be transplanted into acidic soil after their first rain.
River birch has male and female flowers, or catkins. Male catkins are smaller than female catkins and form in the fall and mature in the spring to release pollen. They are wind pollinated and shed their pollen shortly after release. Female catkins are longer and grow on spur-shoots.
Cold- and drought-tolerant
The River Birch Tree is cold and drought tolerant, making it an excellent choice for landscape gardens. The trees grow fast and have attractive bark. However, there are many problems associated with white-barked birches, including pests and diseases. Therefore, it is best to choose a tree from its native range. This tree grows well in cooler climates and prefers moist soil.
The River Birch is a popular tree, and there are many cultivars available. The Dura-Heat variety has improved drought and heat tolerance. It also has superior foliage. The tree grows to 30 to 40 feet in height. It produces female and male catkins, with cone-like fruit that sheds small nutlets. The bark on the River Birch Tree is smooth and flaky, and the trees have a distinctive and attractive shape.
Long-lived
The River Birch tree is a great choice for your landscaping needs. Its irregular leaves with cream-white margins brighten up your landscape and are ideal for partial shade. Its foliage turns golden yellow in fall, making it the perfect tree for Back-to-School pictures and football watch parties.
The River Birch is a native of the southeastern U.S., and it can survive in USDA Hardiness Zones four to nine. Because of its attractive, peeling bark, it's widely planted. Its outer bark is a light shade of gray, while its inner bark is a rich salmon hue. When it's mature, it grows 30 to 40 feet tall, with a crown that is irregularly shaped. Because the species is native to moist areas, the lifespan of the tree is extended, enabling it to thrive in landscapes.
Attractive
The attractive bark of the River Birch Tree gives the tree a striking appearance. Its salmon-pink to reddish-brown outer bark exfoliates to reveal the lighter inner bark. The leaves are wedge-shaped and sharply pointed, and the lower surface is lighter than the upper surface. This characteristic attracts an assortment of wildlife to the tree. Besides bees and squirrels, Ruby-throated hummingbirds also seek out the tree's sap wells.
This tree grows slowly, and reaches a height of only 15 feet. Its leaves are variegated, with yellow edges on the outer and white margins on the inner. The leaves may turn green or turn white during the winter months, so be sure to remove them when they are done. The inner trunk of the tree is a light reddish brown.
Easy to grow
River birch trees are a great low-maintenance landscaping alternative. These trees are very easy to propagate from seed or stem cuttings. This makes them ideal for urban gardens and patios. Once established, river birch trees grow very fast and are easy to maintain.
These trees have attractive bark and are generally grown in multi-trunk varieties. Their outer bark is a salmon-pink to reddish brown and peels off to reveal a lighter inner layer. They also have tough, medium-to-dark green leaves with toothed margins.
