Topworking
Topworking changes the cultivar carried by an established tree by grafting selected scions onto suitable branches or regrowth. On mangoes it can replace an unsatisfactory selection or create a multi-cultivar tree without starting with a new root system. The operation needs planning for branch structure, exposed bark, vigorous competing shoots, and the balance of new grafts. Large cuts and heavy canopy removal create risks, so an established tree should not be stripped indiscriminately in pursuit of a quicker crop.
