I have a dwarf crab apple tree .That with all the snow this year had gotten attacked by bunnies eating the bark.Now most of the bottom branches are bare.What can i do to preserve this tree ?
Any branches that have been stripped of bark all the way around are dead and should be pruned off. If the trunk has been stripped of bark all the way around, then the tree above that is dead. It will need to re-grow a new trunk from below the damage…a long process.
