    This sounds like lichen, which is actually a symptom rather than a cause of the problems on the trees. Lichen often like trees or branches that are dying or dead, which leads many people to think that the lichen is to blame for the problem.

    If your garden is often waterlogged, you may have a fungus in the roots of the trees that are killing them. Are you seeing any other signs of problems in the trees? What do the leaves look like when the branches are dying?
