There are different techniques in grafting.One of them is cleft grafting.In cleft grafting we make a small V cut in the stalk and then insert the pointed end of the scion in the stalk.This is best done in the spring and is useful for joining a thin scion about 1 cm (0.39 in) diameter to a thicker branch or stock.It is best if the latter is 2–7 cm (0.79–2.8 in) in diameter and has 3-5 buds.The branch or stock should be split carefully down the middle to form a cleft about 3 cm (1.2 in) deep.If it is a branch that is not vertical then the cleft should be cut horizontally.The end of the scion should be cut cleanly to a long shallow wedge,preferably with a single cut for each wedge surface,and not whittled.A third cut may be made across the end of the wedge to make it straight across.
Slide the wedge into the cleft so that it is at the edge of the stock and the centre of the wedge faces are against the cambium layer between the bark and the wood.It is preferable if a second scion is inserted in a similar way into the other side of the cleft.This helps to seal off the cleft.Tape around the top of the stock to hold the scion/s in place and cover with grafting wax or sealing compound.This stops the cambium layers from drying out and also prevents the ingress of water into the cleft.
