CLEFT GRAFT
Cleft grafting is a very simple and commonly used grafting method. The scion may be anywhere from ⅛" to 4" in diameter. Cut off the root stock at the right angle in relation to its main axis. Use a knife for small stock and a clefting tool for large stock to split the stock down the center for 1 to 3 inches. If the stock is large, it may be necessary to drive a wedge down the center of the stock to open the split to receive the scion. If the scion is within half the diameter of the root stock, only one scion will be used. If the scion is less than half the diameter of the root stock, two scions will be used. The scion is tapered as shown in Fig. III. Insert the wedge of the scion into the stock so that the cambium layers are in contact on one side or both. The scion should completely fill the split in the root stock so that contact exists along the length of the entire wedge. Wrap the union with grafting tape and cover the entire scion with a plastic bag.
