Green gage plum rootstock damage
Would anyone be able to tell me whats going on with my plum tree. I planted it last spring and I was doing a check on all my trees today and I see this on my plum tree, on the rootstock only just below the bud union. Doesnt look like rabbit damage. The barks seems to be shredding vertically along the length of the trunk. The rest of the tree seems fine. I covered my tree with a tree wrap and took it off a week ago and it was fine. Will the tree survive? Do I need to do any special spraying/care? Is it a disease of the rootstock? Everything was under snow, which is just beginning to melt but the ground is very wet. I covered the tree base with a white tree protector roll.
Thanks a lot.
