Birches (Bentula) are considered pioneer trees because they make little demands on the soil. Because of their white bark, they are welcome ornamental plants in many gardens. However, caution is advised if a tree fungus attacks the birch tree.
How do I prevent tree fungus infestation on my birch?
Tree fungi such as tinder fungus and birch fungus often grow on birches, which can cause fatal damage to the trees. To avoid infestation, seal wounds, provide adequate watering, and prevent nutrient deficiencies.
Which tree fungi grow on the birch?
Under the tree fungi growing on the birchtinder fungus(Fomes fomentarius) and thebirch fungus(Formitopsis betulina).
The fruiting bodies of the tinder fungus, which can reach a diameter of up to 30 centimeters, are thick and inverted console-shaped. The top of the mushroom is crusty and has a light gray or pale brownish color. The Birkenporling has a whitish-cream cap that turns ocher-brown with age. It grows up to 30 centimeters wide. The fruiting body protrudes from the trunk between 5 and 20 centimeters.
What damage do tree fungi cause to birch trees?
Both tree fungi that grow on birch trees are parasites that aredeadly to trees. The tinder fungus uses wounds on the trunk and branches to penetrate the tree. White rot occurs inside the tree. The birch porling causes brown rot. In both cases, the wood becomes brittle, so that the birch tree breaks off at the height of the fungal attack.
How can I fight a tree fungus on the birch?
Once the tree fungus has penetrated the birch tree,fighting is no longer possible. Since removing the tree fungi does not bring any benefit, you should protect the birch tree from infestation. Preventive measures are:
- Seal or avoid wounds and injuries
- Make sure the birch tree is sufficiently watered
- Avoid nutrient deficiencies
Tip
Schillerporling slate in the northern part of Germany
The Leaning Schillerporling (Inonotus obliquus) forms thin fruiting bodies that can be up to one meter long. The typical feature, however, is its black tubers, which can grow up to 40 centimeters wide. Like birch fungus and tinder fungus, this tree fungus is also deadly to birch trees. Measures to combat it are not yet known.
