One method of grafting has been employed extensively for the production of nursery stock in Florida, and another has been used on a limited scale for top-working old trees.
The system extensively used is a modified form of the side-graft employed with other plants. The seeds are germinated in a seed-bed; when the sprouts have reached a height of 5 or 6 inches the plants are dug and laid on the bench. A cut an inch long is made on one side of the sprout, just above the seed, and a thin section of the stem removed, exposing the tissues. The cion is then taken from the tip of a very small branchlet, preferably one which has not fully matured. It should be about 1 inch long, and provided with one or two axillary buds as well as the terminal. It is trimmed on one side to a tapering point at the lower end, and this cut surface is placed against the cut on the stock, after which it is bound carefully in place. The plant is then potted, placed under partial shade, and carefully watered from day to day. After a union is effected, the top of the seedling is removed and the cion allowed to develop.
