Wedge grafts are used for top grafts and top working.
Wedge grafts for top working.
Wedge grafting is used for top grafts when the scion stem diameter is less than the rootstock's stem diameter. The scion is cut with a sharp grafting knife using a single motion. It is cut on both sides of the stem to form a wedge.
The scion is placed into the wedge-shaped cut at the top of the rootstock.
The graft is wrapped in plastic grafting tape and the cut and exposes surfaces of the graft are covered with grafting wax.
