Thank for the compliments. I think you are right about the compatibility issue! I think it is better to graft to trees that are all ready in their location. When I dug up the rootstocks, I had to cut the tap root. I was really hard digging them up. I would not think small trees, the size of one your finger would have some many roots.
Next door, I grafted on the trees and didn’t have to dig them up. I grafted about 8 trees that where about 1/2 in diameter. Some pictures below. I hope the deer don’t eat them.
