resistance to soil-borne pests, and increases environmental tolerance. Ideas of possible

tongue graft, side veneer graft, cleft graft, and stenting. The whip or tongue graft is used
mainly for fruit trees. The side veneer graft is used for evergreens, such as the blue

or grafting to a rootstock that is considerably larger than the scion. Stenting is used
frequently with roses.
