Veneer-Grafting.--Fig. 75 shows a style of grafting which is much used, particularly for ornamentals and for rare stocks which are grown in pots. An incision is made upon the stock just through the bark and about an inch long (_A_, Fig. 75), the bit of bark being removed by means of a downward sloping cut at its base. The base of the cion is cut off obliquely, and upon the longest side a portion of bark is removed, corresponding to the portion taken from the stock. The little tongue of bark on the stock covers the base of the cion, when it is set. The cion is tied tightly to the stock (_B_, Fig. 75), usually with raffia. This method of grafting makes no incision into the wood, and all the wounded surfaces are completely covered by the matching of the cion and stock. It is not necessary, therefore, to wax over the wounds, as a rule. The parts grow together quickly and uniformly, making a solid and perfect union as shown at _D_, Fig. 75. So far as the union of the parts is concerned, this is probably the ideal method of grafting. This method, which is nothing but the side-graft of the English gardeners with the most important condition of the longer tongue on the stock, is known by various names, but it is oftenest called veneer-grafting in this country. [Illustration: Fig. 75. Veneer-grafting.] Veneer-grafting is employed mostly from November to March upon potted plants. Stocks which are grown out-doors are potted in the early fall and carried in a cool house or pit. The cion is applied an inch or two above the surface of the soil, and the stock need not be headed back until the cion has united. (See Fig. 76.) Both dormant and growing cions are used. All plants in full sap must be placed under a frame in the house, in which they can be almost entirely buried with sphagnum, not too wet, and the house must be kept cool and rather moist until the cions are well established. Some species can be transferred to the open border or to nursery rows in the spring, but most plants which are grafted in this way are handled in pots during the following season. Rhododendrons, Japanese maples and many conifers are some of the plants which are multiplied by veneer-grafting. This method, when used with hardy or tender plants, gives a great advantage in much experimental work, because the stock is not at all injured by a failure and can be used over again many times, perhaps even in the same season; the manipulation is simple and easily acquired by inexperienced hands.
