I’ve got a Craig’s Crimson cherry on NewRoot1 that was starting to leaf out this spring, then disaster struck. All the leaves dried up, and further investigation found holes in the trunk, and complete girdling. All the damage occurred right at the graft point, so I’m not holding out any hope for the Craig’s Crimson. The rootstock is putting out suckers - which i’m letting grow to act as “nurse branches”. Should I just let them grow over the summer, and in the spring graft some new scion wood on?
I think that is the best way for now. You may leave 2 to 3 branches for a multi grafts sweet cherry tree. Good luck.
