All cuts should be straight and smooth. C) Make a cleft cut down the stock. The cut should be about 3/4 inch in length and one-third of the distance down from the tip of the diagonal cut. D) Make the same type of cleft cit in the scion. E) Place scion on stock, interlocking the cleft cuts and matching the cambium layers of stock and scion on one side of the graft.
