Grafting is a technique for joining two plants so that they grow as one. The upper part of the combined plant, the ‘scion’ or ‘graft’, consists of a twig or shoot that is placed on the root system of another plant. The graft is placed is such a way that it can connect to the sap flow of the rootstock and form the new plant. The new shoots that grow from the graft will have the same DNA as the graft, but not as the rootstock. Grafting is therefore a form of asexual propagation. See also the horticultural technique ‘budding’.
