Quick Fact!
Birches are also known as 'pioneer species' due to their ability to grow on uncolonized lands. Heathlands or dwarf-shrub habitats face a major threat from the advancing birches if their (birch) saplings are not grazed in a timely manner.
Birch belongs to the genus Betula and is grouped under the Betulaceae family. These are medium-sized plants which grow 40-50 feet tall. Leaves of the birch can be either pointed or toothed. The type of fruit bore by the birches is known as 'samara'. The samara fruits are formed of papery/fibrous tissues which develop from the walls of ovary.
Facts about Birch Tree
Some of the useful facts and details about the birch tree are listed below.The name, 'birch' has originated from a Germanic term, birka. 'Betula' (genus of birch) is a Latin word. The birch needs a well-drained and preferably, sandy soil for its healthy growth. The soil has to be rich in organic matter. Birch tree is mainly found near water sources. One of the reasons behind this is its shallow root-system. Types of the birch commonly found in nature are Yellow Birch, European White Birch, Gray Birch and Paper Birch.

Leaves of this tree have an elliptical shape.
The birch tree needs enough sunlight to attain a healthy growth.
Most birches, except for Paper birch and River birch need low pH soils for a healthy growth.
The major birch tree diseases which can hamper their growth are - leaf blister, birch anthracnose, birch canker and wetwood/slime flux. In Birch Anthracnose, the irregular-shaped and brown-colored spots (with dark brown margins) appear on leaves. In such cases, spraying of appropriate fungicides help in birch tree care.
In the diseases like slime flux and bacterial wetwood, anaerobic soil bacteria infect the heartwood. These bacteria feed on wood and release carbon dioxide, methane and fatty acids. Draining the liquid on the ground by means of a tube is one of the solutions to control the problem. Raising the pH levels also helps prevent the heartwood from rotting.
