Crown or Bark Graft
For this graft the stock is sawed off as if for a cleft graft, but the incision is made, as shown above, to include the bark only, exposing the cambium layer. The cion, cut wedge shape is inserted, and a waxed bandage is applied. The cion here is not at first held quite so securely as in case of a cleft graft, but, on the other hand, the stock is not split, which is an advantage.
