Peeling Bark on Maples
The bark is peeling off my larger maples about 2 -6 inches above the soil level. All maples were 5 gallon size planted in the last 6 months to 1 year. On two trees, bark is peeling in neat strips above or below the graft. On the other trees, bark is peeling from what seems to be scratch or gnaw marks on the trunk. Is this the work of squirrels, neighborhood cats, or something else? Could dry soil be responsible for peeling bark?
