Video: William Seabrook demonstrates whip & tongue grafting, and rind grafting

In this video, William Seabrook provides a close-up demonstration of whip & tongue grafting, on a fifteen-year old tree that will be changed to a different variety. In the first section, he explains exactly how to make the cuts in the tree and the scion to ensure that the graft is successful. The double cut enables optimum contact between the vascular cambium tissues of the two parts and holds the scion firmly in place, ready to be securely fastened with the sealing tape and grafting wax. Callousing will appear within three to four weeks.

The rind graft method is used to create a graft on a larger piece of timber. The first diagonal cut is followed by a short cut at the end of the scion to create a point, and then another cut that creates a 90-degree angle in the cambium tissue. The bark of the parent branch is cut for a length corresponding to the scion, and then the knife is used to lift the bark. The scion is then inserted so that the right-angled surfaces come into contact with the corresponding surfaces in the branch. The graft is finished in the usual manner, with sealing tape, and then grafting wax is applied to seal the cut surfaces to prevent the entry of air or rain. The grafting wax should be applied generously because the rising sap has a tendency to push out from the cut surfaces. Click to watch.
