My second step in maintaining this graft is to trim the top of the stock. If you look carefully, you'll see a distinctive swelling in the stock's bark that runs at a diagonal from scion to the opposite side of the tree--about 1.5 inches down the trunk. To enhance the healing process, I'll cut the corner off the stock just above that swelling.
By trimming the stock at the precise location the tree is trying to seal off the wound, you will enhance the healing process and reduce the time needed to keep the graft supported with a wooden stake.
The final step in early spring maintenance is to prune the tree. Remove some of the lower limbs to force more of the tree's energy into the scion (note the fresh pruning wound below the graft union). Next, prune the scion so you'll have a nice central leader tree.
