At the position of the graft, the tree is somewhat weak. It is not s
structural weakness but a growth weakness. Nutrients going up from the
roots and down from the leaves slow at that point. This does not affect
the shoot from the rootstock, which will eventually dominate the plant.
In the end, the grafted top might wither and die.
