Seed-fruit can be budded into any other seed-fruit, and stone-fruit into any other stone-fruit; but stone and seed-fruits, cannot be thus mingled.
Rose bushes can have a variety of kinds budded into the same stock. Hardy roots are the best stocks. The branch above the bud, must be cut off, the next March or April after the bud is put in. Apples and pears, are more easily propagated by ingrafting, than by budding.
Ingrafting is a similar process to budding, with this advantage; that it can be performed on large trees, whereas budding can be applied only on small ones. The two common kinds of ingrafting, are whip-grafting, and split-grafting. The first kind is for young trees, and the other for large ones.
The time for ingrafting, is from May to October. The cuttings must be taken from horizontal shoots, between Christmas and March, and kept in a damp cellar. In performing the operation, cut off, in a sloping direction, (as seen in Fig. [41],) the tree or limb to be grafted. Then cut off, in a corresponding slant, the slip to be grafted on. Then put them together, so that the inner bark of each shall match, exactly, on one side, and tie them firmly together, with woollen yarn. It is not essential that both be of equal size; if the bark of each meet together exactly on one side, it answers the purpose. But the two must not differ much, in size. The slope should be an inch and a half, or more, in length. After they are tied together, the place should be covered with a salve or composition of beeswax and rosin. A mixture of clay and cowdung will answer the same purpose. This last must be tied on with a cloth. Grafting is more convenient than budding, as grafts can be sent from a great distance; whereas buds must be taken in July or August, from a shoot of the present year's growth, and cannot be sent to any great distance.
