Grafting Method - Wedge or Cleft Grafting

Wedge or Cleft Grafting



This method is generally used in the propagation of deciduous fruits and top working older trees of inferior varieties. Branches of the rootstock 1.25-5 cm thick or even larger are cut at the top, and a vertical split 5-8 cm deep id made in the center of the stub with a heavy chisel or knife.
The split is kept apart until scion containing at least three buds is inserted. The basal end of the scion is cut into a long sloping wedge about 5 cm long. The side of the wedge which is to face outward is made slightly wider than the inside edge. One scion is inserted in each side of the split. After adjustments of the scion, the tool used to keep the split open is removed to allow the full pressure of the split stock to bear on the scions at the point where the cambium of stock and scion are in contact. No tying is usually needed; however, all the wounded surfaces are thoroughly waxed over. Cleft grafting is the most successful when in early spring when the buds are beginning to swell but before active growth has started.


Cleft grafting is a grafting technique which allows the union of a rootstock limb that is much larger in size than the scion piece
