The appearance of lichen on a tree will not lead to anything good. At first glance, it seems that it is so delicate, lacy, a creation of nature, but appearances are deceptive. This must be remembered and not given the opportunity to capture the entire plant.

Why do lichens appear on trees and bushes

There are several reasons for the appearance of these symbiotic organisms. If they have found their place on a certain tree, then it is weakened and cannot resist the invasion. The cause may also be a lack of nutrition or the activity of pests. Lichen often occurs where trees and shrubs grow in the dark and with high humidity.

Why you need to fight lichens

First of all, lacy growths become an impeccable home for various pests and pathogens. Lichens can harm plants. They cover the bark, which prevents moisture from evaporating. This leads to the development of fungal infections.

Lichens block access to sunlight, interfere with air exchange. Without this, the plant can quickly dry out. And, as mentioned above, pests hibernate en masse in lichens. Therefore, every autumn it is necessary to carry out tree sanitation, process and clean branches and trunks.
