CANNABIS CULTURE – Grafting is a procedure in which two plants are fused together, to make a single, two-part plant. The part below the graft union, including the roots and lower stem, is known as the rootstock. The top part of the plant, above the graft union, which bears leaves and fruit, is known as the scion.

References to grafting appear in Chinese and Greek texts from the fifth and fourth centuries B.C.E., respectively, and indicate that the practice became prevalent centuries earlier. In the past few decades, vegetable growers also began grafting for various benefits. Cannabis too, can be grafted quite easily, and there are many possible applications.

In the year 2000, growers in Japan and Korea grew 700 million grafted vegetables. Vegetables, and other plants such as fruit trees and ornamentals, can benefit from rootstocks that are resistant to pests and pathogens. Breeders develop rootstocks resistant to diseases like root rot, infestations of root-knot nematodes, or even to attack from insects such as Phylloxera (which are often incorrectly referred to as ‘root aphids’, although they’re closely related).
