Cut a "T" in the bark of the rootstock tree with a grafting knife.
Cut a scion, or budding stick, from the base of the branch. Choose a scion that is new growth, but sturdy and no longer green. Make a sharp, angled cut in the scion.
Place the angled cut end of the scion into the cut "T" in the rootstock.
Wrap grafting tape around the graft to seal it from the elements and secure the union. Leave the bud uncovered.
Wait three weeks and inspect the new growth. Unwrap the graft if the union was successful.
