Q.Bark Damage Caused by Deer
We have had a large buck deer come through our front yard this past winter/spring regularly. The deer decided he liked our little red maple tree to rub on. The bark has been damaged about three feet long and a third of the way around the tree, which is about four inches in diameter. What should we do to help the tree heal?
