I have a tree that has many branches covered with lichen. Should this be removed, and if so what is the best method? .
The same goes for moss here in Vancouver. Neither will hurt the tree. If you want to get rid of them though, spray the tree with lime-sulphur before bud break. This kills the moss and lichen. You can also use a stiff brush. Careful not to scratch the bark and read the label before using Lime Sulphur as it shouldn't be used on some trees and plants.
