Cutting-grafting.--Cuttage and graftage are combined in various ways. Cuttings of plants which root with difficulty are sometimes grafted upon those which root easily. When the plants are transplanted, the following autumn or spring, the nurse or stock can be removed, the cion having taken root. Root-grafting with a long cion, described on a previous page (78), is virtually a grafting of cuttings. In other cases, union with an uncongenial stock is facilitated by allowing the cion to project downwards beyond the point of union and to stand in the soil or moss or a dish of water. Fig. 88 is a good illustration of the practice. The cion extends into the soil nearly as far as the root itself. After union has taken place, the lower part of the cion is removed. This method can be used for some magnolias, mulberries, birches, and many other plants of which some kinds root with more or less difficulty. Bottle-grafting, described in most of the books, is essentially this method, modified by letting the end of the cion drop into a bottle of water. Sometimes a portion of the bandage is allowed to hang in water, to keep the cion fresh until the parts join. [Illustration: Fig. 88. Cutting-grafting.] =Inarching.=--Inarching or grafting by approach is the process of grafting contiguous plants or branches while the parts are both attached to their own roots. When the parts are united, one of them is severed from its root. Fig. 89 explains the operation. In this case, the larger plant is designed for the stock. When the smaller plant has united, it is cut off just below the union and it thenceforth grows upon the other plant. Limbs of contiguous trees are sometimes grafted in this way. It is the process employed by nature in what is called natural grafting. Grape-vines are often inarched. A thrifty young branch may be inarched into the stem of a fruit upon the same tree, thus supplying the fruit with additional food and causing it to grow larger than it might if undisturbed. To join the parts, it is only necessary to remove the barks between the stock and cion and then tie the two together snugly. If out-doors, the junction should be waxed over; and it is then necessary, also, to secure the branches in such manner that the wind cannot loosen them. The parts are sometimes joined by a tongue, after the manner of a whip-graft, but this is rarely necessary. Oranges and camelias were often propagated by inarching in the old practice, but this work is now much more easily done by the veneer-graft.
