My readers will perceive, that Fall-pruning, or shortening-in the ripened wood of the vine, and summer-pruning, shortening in and thinning out the young growth, have one and all the same object in view, namely, to keep the vine within proper bounds, and concentrate all its energies for a two-fold object, namely, the production and ripening of the most perfect fruit, and the production of strong, healthy wood for the coming season's crop. Both operations are, in fact, only different parts of one and the same system, of which summer-pruning is the preparatory, and fall pruning the finishing part. If we think that a vine is setting more fruit than it is able to bear and ripen perfectly, we have it in our power to thin it, by taking away all imperfect bunches, and feeble shoots. We should allow no more wood to grow than we need for next season's bearing; if we allow three canes to grow where only two are needed, we waste the energies of the vine, which should all be concentrated upon ripening its fruit in the most perfect condition, and producing the necessary wood for next season's bearing, and that of the best and most vigorous quality, but no more. If we prune the vine too long, we over-tax its energies; making it bear more fruit than it can perfect, and the result will be poor, badly-ripened fruit, and small and imperfect wood. If, on the contrary, we prune the vine too short, we will have a rank, excessive growth of wood and leaves, and encourage rot and mildew. Only practice and experience will teach us the exact medium, and the observing vintner will soon find out where he has been wrong, better than he can be taught by a hundred pages of elaborate advice. Different varieties will require different treatment, and it would be foolishness to suppose that two varieties so entirely different, as for instance, the Concord and the Delaware, could be pruned, trained and pinched in the same manner. The first, being a rank and vigorous grower, with long joints, will require much longer pruning than the latter, which is a slow-growing, short-jointed vine. Some varieties, the Taylor for instance, also the Norton, will fruit better if pruned to spurs on old wood, than on the young canes; it will therefore be the best policy for the vintner in pruning these, to retain the old arms or canes, pruning all the healthy, strong shoots they have to two buds, as long as the old arms remain healthy; always, however, growing a young cane to fall back upon, should the old arm become diseased; whereas, the Catawba and Delaware, being only moderate growers, will flourish and bear best when pruned short, and to a cane of last season's growth. The Concord and Herbemont, again, will bear best on the laterals of last season's growth, and should be trained accordingly. Therefore it is, because only a few of the common laborers will take the pains to think and observe closely, that we find among them but few good vine-dressers.
