PINCHING—BUD-NIPPING “When the desired shape has been obtained the next thing is to keep it, despite all opposition on the part of the tree, which revolts in its own peculiar fashion; that is, it strives to restore the natural conformation of its branches. Suppose, for example, that a pear-tree, pruned after the manner of wall-fruit, has grown all out of symmetry and developed one side more than the other. How shall the two halves be restored to correct proportions? How shall the too vigorous part be weakened and the too feeble part strengthened? Several methods offer themselves. “On the vigorous side let us cut back the branches with the pruning shears, leaving only the base of each with a small number of buds; in other words, let us cut them very short. On the weak side, on the contrary, let us leave the branches intact or cut them very long, thus leaving them the greater part of their buds. What will come of this treatment? Since abundant foliage, the active laboratory of the descending sap and also a kind of pump that sucks up the sap and causes it to ascend from the roots, is the prime cause of vigorous vegetation, the weak part, with its numerous buds developed into leafy shoots, will grow stronger, while the strong part, with its small number of buds, will become weaker. Both effects will tend to the same result: the restoration of the desired symmetry. “With the ends of the fingers and the help of the thumb-nail, it is customary to pinch off from the too vigorous side the tips of the young branches while they are still tender. This operation we may call pinching. The sap that would have been used for the development of these branches is diverted from its course and carried toward the weak shoots, which it renews and stimulates. If the weak side itself needs pinching to arrest shoots that impair the desired symmetry, the operation is postponed as long as possible, while on the strong side it is carried out very early. The sap thus turned away from the vigorous side toward the ailing one has a whole season in which to restore the lost equilibrium. “Instead of limiting ourselves to pinching off the tips of the young shoots with our thumb-nail, we can suppress them altogether while they are still tender. This is done as early as possible on the strong side, only the indispensable shoots being left. If it is necessary on the weak side, it is not done until the latest possible moment. This operation we may style bud-nipping, since the word ‘bud,’ by which we designate the germ of the future branch when it is still enveloped in scales, applies also for the sake of convenience to the branch already developed but still young and tender. It is evident that nipping off the buds from the strong part tends, [ ]even more than pinching, to promote the desired growth of the weak part. The more branches we suppress entirely, the fewer will be left to share the sap needed by the branches we wish to strengthen. 122 “What turns aside the sap from the part pruned, pinched, or nipped, toward the part left intact, is evidently the more or less complete suppression of foliage. It is primarily the leaves that by the continual evaporation of which their surface is the seat determine the ascent of the liquid drawn from the soil by the roots. The more numerous these leaves are at any one point, the more abundant the flow of sap to that point; the scarcer they are, the less the flow of sap. To diminish at any point the number of leaves by pinching, bud-nipping, or any other means, is therefore to diminish at the same point the flow of sap, which will go in some other direction, to the parts that have more leaves and hence a more rapid rate of evaporation to summon the sap. It is plain, then, that a middle course may be followed between the pinching that partly suppresses the foliage of a young branch and the bud-nipping that suppresses it entirely. This middle course consists in cutting a certain number of leaves from the too vigorous shoots; and they should be cut clean without tearing, by severing the stem and leaving its base undisturbed. “The easiest way for the sap to run from the roots to the foliage is from bottom to top in a vertical line. Anything that interferes with this course hinders also the upward impetus. Thus in branches [ ]with sharp elbows and abrupt bends the rush of sap is slackened just as the rate of flow of a water-current is diminished by the windings occurring in its bed. Thus, again, in a branch having a decided incline downward the sap moves with difficulty, because its movement toward the extremity of this branch is in a direction contrary to that which is natural to it. The application of this principle is evident. If we wish to moderate a too vigorous growth of branches, we bend them toward the ground; if we wish to stimulate a too feeble growth, we straighten up the branches until they assume a vertical posture. 123 “We can also turn to account the exhausting effect of fruit-bearing. The more fruitful a branch is, the weaker it becomes, since the use of sap in fruit means so much the less for foliage, and it is foliage that invigorates the branch. Accordingly we will leave the greatest possible quantity of fruit on the strong part of our tree, and suppress it on the weak part.” About HackerNoon Book Series: We bring you the most important technical, scientific, and insightful public domain books.
