Cherries (Prunus spp.) are beautiful but often short-lived trees that are susceptible to a host of


diseases, pests and cultural problems. Splitting or peeling bark is often a sign of frost damage, though it may also be caused by disease or herbicide injury. With proper cultural care, cherry trees can often heal themselves with minimal scarring.

Frost Damage

After a chilly winter night, the south- and east-facing sides of a cherry tree may split as the morning sun causes the bark to warm, expand and break. The tree will heal on its own, forming callused scabs. To prevent this, paint the trunk with whitewash to help reflect light. Paint the trunk only when it has no open wounds. You can wrap the tree with plastic, paper or cardboard to keep it warm while it heals.
