Freddy Menge has graciously brought his grafting tutorial online.
In this video, Freddy demonstrates cleft grafting via a proven method that has gotten many local newbies propagating deciduous fruit trees for the first time. He makes mention of knife style (and “caveman grip”), cleft graft technique, the physiology of grafting (cambium contact), tensioning and sealant materials (demonstrating an inexpensive and effective graft with masking tape), and post-graft training (removal of competing shoots).
