cleft-grafting

This type of blade in some measure prevents the bruising of the bark when splitting the branch in cleft-grafting.

The Pecan and its Culture 1920

I have generally had the best success in grafting here about the middle of March, in the following manner: Dig away the ground around the vine you wish to graft, until you come to a smooth place to insert your scion; then cut off the vine with a sharp knife, and insert one or two scions, as in common cleft-grafting, taking care to cut the wedge on the scion very thin, with shoulders on both sides, as shown in Figure 4, cutting your scion to two eyes, to better insure success.
