The greatest disadvantage in its use in the budding field is its habit of rolling when it becomes dry. [Illustration: Fig. 64. Bud entering matrix.] In two or three weeks after the bud is set it will have "stuck" or united to the stock. The bandage must then be removed or cut. It is the common practice to draw a budding-knife over the strings, on the side opposite the bud, completely severing them and allowing them to fall off as they will. If the strings are left on too long they will constrict the stem and often kill the bud, and they also have a tendency to cause the bud to "break" or begin to grow. The bud should remain perfectly dormant until spring, for if it should begin to grow it will be injured and perhaps killed by the winter. It should remain green and fresh; if it shrivels and becomes brown, even though it still adheres to the stock, it is worthless. Advantage can be taken, when cutting the tyings, to rebud any stocks which have failed. If the bud should begin to grow, because of a warm and wet fall or other reasons, there is little remedy except perhaps to head the shoot back if it should become long enough. If the stocks are protected by snow during winter, some of the buds at the base of the shoot may pass the cold in safety. [Illustration: Fig. 65. The bud tied.] The next spring the stock should be cut off just above the bud (Fig. 66), in order to throw the entire force of the plant into the bud. If the root is strong and the soil good, the bud will grow two or three feet the first year; or peaches and cherries will grow from two to three times that height. All sprouts should be kept rubbed off the stock, and the bud should be trained to a single stem. In some weak and crooked growers, the new shoot must be tied, and some propagators in such cases cut off the stock five or six inches above the bud and let it serve as a stake to which to tie. The stock, of course, must not be allowed to grow. Late in the season the stock is cut down close to the bud, as in Fig. 66. Peaches and some other fruits are sold after having made one season's growth from the bud, but pears, apples, and most other trees are not often sold until the second or third year.
