Answer 1

While lichens generally don’t harm the tree, an abundance of lichen can result in poor growing conditions for the fruit tree. For example, lichens or fungus growing on the leaves can interfere with photosynthesis process while a thick growth of lichens on stems could add extra weight that results in damage twigs.
