I have a crabapple tree, about 12 years old. Just recently a large patch of bark either fell off or was chewed off by quirrles or other rodents not sure of the origin of the problem. It is at a significant weight bearing part of the tree, originally I thought it may be cracked, but a close look shows no signs of a crack.
Should I paint some kind of pitch or other product on it to protect the underlying wood?
