So, in making a graft, one must match the tissues of the scion with the corresponding tissues of the stock. Especially must cambium be matched with cambium. It is also important that a close joint be made and that the place of union of stock and scion be protected, usually by grafting- wax, until the wounded tissues have healed. Of the many methods of grafting that have been devised, only a few of the commoner ones will be mentioned. In a cleft graft the stock is split, and the scion, trimmed to a wedge shape, is inserted in the split. This method is largely used in the grafting of fruit trees, when the graft is made some distance.
