Fig. 18.—AMERICAN BUDDING. b, THE BUD WITH THE WOOD REMAINING.
A division of labor is had generally, so far as the tying is concerned; for this is done by a boy who follows immediately after the budder, and some of these require two smart boys. S.S. Jackson has carried this principle of division of labor still further, and, as appears, with advantage; one hand cuts the shields for another who inserts them. He never uses the haft of his knife to raise the bark, but, after having made the longitudinal cut through the bark, he places the knife in position to make the transverse incision, and as he cuts the bark, the edge of the blade being inclined downward, the shield is placed on the stock close above the knife, which is then still further inclined toward the stock, resting upon the shield as a fulcrum; thus started, the bark will readily yield to the shield, which is then pressed down home into its place.
Fig. 19.—MR. JACKSON'S METHOD OF MAKING THE INCISION.
J.W. Tenbrook, of Indiana, has invented a little instrument with which he makes the longitudinal and transverse incisions, and raises the bark, all at one operation, and inserts the bud with the other hand. On these plans, two persons may work together, one cutting, the other inserting the buds; these may change work occasionally for rest. In all cases it is best to have other hands to tie-in the buds, two or three boys will generally find full occupation behind a smart budder. It will be apparent that the above processes can only be performed when the stock is in the most perfect condition of growth, so that the bark can be pressed away before the bud; a good workman will not desire to bud under any other circumstances.
In budding, it is found that the upper end of the shield is the last to adhere to the stock; it needs to be closely applied and pressed by the bandage, and if too long, so as to project above the transverse incision, it should be cut off.
Fig. 20.—STICK OF BUDS.
Fig. 21.—RING BUDDING.
Another expedient for facilitating the operation of budding is made use of by some of the nurserymen who grow peach trees extensively. It consists in, preparing the stick of buds, as shown in the engraving, figure 20. A cut is made, with a sharp knife, through the bark, around each bud, as in the figure. The budder then removes the buds as they are wanted, with a slight sidewise pull, and has the shield in the right condition to insert, without the trouble of removing the wood. When working in this manner, the stick of buds must not be allowed to dry, and the work must be done at a time when the bark parts with the greatest ease.
Among the modifications of the process of budding, that, called ring-budding, fig. 21, may be mentioned, rather as a curiosity however, though preferred by some, especially for the grape, which is said to be very easily budded, though we seldom see the operation practiced.
Those who are anxious to commence budding early in the season, prepare the scions they expect to use, by pinching the ends and cutting off a portion of the leaves; the effect of this check to the wood growth is to hasten the ripening or development of the buds, which rapidly swell, preparatory to breaking, in their attempt to reproduce the foliage that had been removed.
Tying should be done as soon as convenient after the buds have been inserted; though under very favorable circumstances the bud may adhere and do well without any bandaging, no one thinks of leaving the work without carefully tying in the buds, and most budders lay a great deal of stress upon the necessity for covering the whole shield and cut with a continuous bandaging, that shall exclude the light, and air, and moisture. The material most used is bass matting, brought from Russia, as a covering to the packages of sheet iron for which that country is famous. This is the inner bark of the Tilia Europea, but our own Bass-wood, T. Americana, furnishes an excellent bass, and is procured by our nurserymen directly from the trees, by stripping the bark in June, and after it has lain a few days in water, the inner portion separates easily, is dried, and put away for future use. Those who have not provided the bass, are content to apply woolen yarn to tie in the buds; its elasticity adapts it well to the purpose. The ingenious budder, without bass, often finds a substitute for it, and a very good tie, in the soft husks of corn ears, the inner husks are torn into strips and used a little damp, when they are pliant and easily tied, answering a very good purpose. Many nurserymen, who have tried the corn-husk, prefer it to all other material, because it saves them the trouble of removing the bandages, as it decays rapidly, and yielding to the growth of the stock, it falls off before it cuts the bark, which a firmer bandage is apt to do.
Fig. 22.—MR. JACKSON'S MANNER OF TYING THE BUD.
S.S. Jackson, whose improvements in budding have already been mentioned, also adopts another in tying. He holds that it is not at all necessary to hide the bud with the tie, the only requisite being to retain the parts in contact. He uses No. 3 cotton yarn, cut in lengths of a few inches, more or less, according to the size of the stocks; a couple of strands are pulled out from the cut bundles; the first turn around the stock secures the end of the string by its own pressure, one turn more is taken below the bud and one or two above it, when the free end is passed into a cleft made through the bark above the point where the bud is inserted. This is found to secure the string sufficiently, and is easily loosened when necessary to relieve the tension caused by the continued growth, (fig. 22).
All ties should be loosened in the course of a couple of weeks, if the stocks be growing freely; otherwise they will injure the tree by strangulation. Sometimes it will be necessary to replace the bandage to prevent the effects of desiccation upon the bud, this is particularly the case with the cherry, and other fruits, that are budded early; but the tie is often left on the stock all winter, as a sort of protection to the bud. When loosening the ties, the buds are inspected and their condition ascertained; if they have failed, they may be replaced, if the stocks continue in a suitable condition. It is very easy to tell the success of the budding; the portion of the petiole left upon the shield is a very good index; if the bud has withered, this will also be brown and will adhere firmly to the shield; but, on the contrary, the bud and its shield having formed a union with the stock, the leaf-stalk remains plump, but changes color. Like a leaf-stem in the autumn, it assumes the tint of ripeness, and it will separate with a touch, and soon falls off.
The common method of removing the ties is to cut them with a single stroke of a sharp knife, when the bandage is left to fall off. Mr. Knight recommended two distinct ligatures, and left the one above the bud for a longer time uncut. When the buds have not been very fully developed, and when the stocks are very thrifty, it sometimes happens that the excessive growth about the incisions made for the insertion of the bud, completely cover up this little germ of a future tree, which is then said to be "drowned." Judicious pinching and shortening of the stock will prevent this effect, but care is needed not to pursue such treatment too far.
The stocks are generally headed back to within an inch or more of the bud, just as vegetation starts the next spring; but early set buds may be headed back so soon as they have taken, and will often make a nice growth the same season. This, however, is not generally preferred, and a late start in the growing weather of our autumns is particularly to be avoided, as the young shoot will not become matured before winter, and may be lost.
The advantages of propagating by budding may be summed up in the following remarks, which
