Symptoms


Bark may peel or fall off the tree in sheets, depending upon tree species, in blocks, plates or shreddings. Sloughing or peeling of the bark is a normal process for some tree species. Bark sloughing often begins as trees grow in the spring: The outer layers of bark are dead tissue. When the tree begins to grow in diameter, the outer bark may split or slough.
