notch grafting, a method of grafting vines that resembles cleft grafting. It differs in that the cut trunk is not split across, but instead the scion pieces are cut to fit a V-shaped notch made on either side of the trunk to a length of about 3 cm/1 in. The scion pieces are often tacked into place. Notch grafts are not as secure as cleft grafts. A related method is the bark graft done later in spring when the bark lifts freely, but again the union is sometimes weak.
