In more recent times, a plan has been discovered of planting a dragon branch near the tree—that being the name given to an old stock-branch that has become hard and tough in the course of years. For this purpose, it is cut as long as possible, and the bark is taken off from three-fourths of its length, that being the portion which is to be buried in the ground; hence it is, too, that it is called a “barked”[3155] plant. It is then laid at full length in the furrow, the remaining part protruding from the ground and reclining against the tree. This method is the most speedy one that can be adopted for growing the vine. If the vine is meagre or the soil impoverished, it is usual to keep it cut down as near to the ground as possible, until such time as the root is strengthened. Care, too, should be taken not to plant it covered with dew,[3156] nor yet while the wind is blowing from the north. The vine itself ought to look towards the north-east, but the young stock-shoots should have a southern aspect.
There should not be too great haste[3157] in pruning a young vine, but a beginning should be made by giving the wood and foliage a circular form, care being taken not to prune it until it has become quite strong; it should be remembered, too, that the vine, when trained upon a tree, is generally a year later in bearing fruit than when grown on the cross-piece. There are some persons, again, who altogether forbid that a vine should be pruned until such time as it equals the tree in height. At the first pruning it may be cut to within six feet from the ground, below which a shoot must be left, and encouraged to run out by bending the young wood. Upon this shoot, when pruned, there should not be more than three buds left. The branches that take their rise from these buds should be trained in the following year upon the lowermost stages of the tree, and so in each successive year taught to climb to the higher ones. Care, too, should always be taken to leave one hard, woody branch at each stage, as well as one breeding shoot, at liberty to mount as high as it pleases. In addition to these precautions, in all pruning, those shoots should be cut off which have borne fruit the last year, and after the tendrils[3158] have been cut away on every side fresh branches should be trained to run along the stages. In Italy the pruning is so managed that the shoots and tendrils of the vines are arranged so as to cover the branches of the tree, while the shoots of the vine in their turn are surrounded with clusters of grapes. In Gallia, on the other hand, the vine is trained to pass from tree to tree. On the Æmilian Way, again, the vine is seen embracing the trunks of the Atinian elms that line the road, while at the same time it carefully avoids their foliage.[3159]
It is a mark of ignorance in some persons to suspend the vine with a cord beneath the branches of the tree, to the great risk of stifling it; for it ought to be merely kept up with a withe of osier, and not tightly laced. Indeed, in those places where the willow abounds, the withes that it affords are preferred, on account of their superior suppleness, while the Sicilians employ for the purpose a grass, which they call “ampelodesmos:”[3160] throughout the whole of Greece, rushes, cyperus, and sedge[3161] are similarly employed. When at any time the vine has been liberated from its bonds, it should be allowed to range uncontrolled for some days, and to spread abroad at pleasure, as well as to recline upon the ground which it has been looking down upon the whole year through. For in the same manner that beasts of burden when released from the yoke, and dogs when they have returned from the chase, love to roll themselves on the ground, just so does the vine delight to stretch its loins. The tree itself, too, seems to rejoice, and, thus relieved from the continuous weight which has burdened it, to have all the appearance of now enjoying a free respiration. Indeed, there is no object in all the economy of Nature that does not desire certain alternations for the enjoyment of rest, witness the succession of night and day, for instance. It is for this reason that it is forbidden to prune the vine directly the vintage is over, and while it is still exhausted by the process of reproduction.
Directly the vine has been pruned, it ought to be fastened again to the tree, but in another place; for there is no doubt that it feels very acutely the indentations that are made in it by the holdfasts. In the Gallic method of cultivation they train out two branches at either side, if the trees are forty feet apart, and four if only twenty; where they meet, these branches are fastened together and made to grow in unison; if, too, they are anywhere deficient in number or strength, care is taken to fortify them by the aid of small rods. In a case, however, where the branches are not sufficiently long to meet, they are artificially prolonged by means of a hook, and so united to the tree that desires their company. The branches thus trained to unite they used to prune at the end of the second year. But where the vine is aged, it is a better plan to give them a longer time to reach the adjoining tree, in case they should not have gained the requisite thickness; besides which, it is always good to encourage the growth of the hard wood in the dragon branches.
There is yet another method,[3162] which occupies a middle place between this mode of propagation and that by layers. It consists of laying the entire vine in the earth, and then splitting the stock asunder by means of wedges; the fibrous portions are then trained out in as many furrows, care being taken to support each of the slender plants by fastening it to a stake, and not to cut away the branches that shoot from the sides. The growers of Novara, not content with the multitude of shoots that run from tree to tree, nor yet with an abundance of branches, encourage the stock-branches to entwine around forks planted in the ground for the purpose; a method, however, which, in addition to the internal defects arising from the soil, imparts a harshness to the wine.
There is another fault, too, that is committed by the people of Varracina,[3163] near Rome—they only prune their vines every other year; not, indeed, because it is advantageous to the tree, but from a fear lest, from the low prices fetched by their wines, the expense might exceed the profits. At Carseoli they adopt a middle course, by pruning away only the rotten parts of the vine, as well as those which are beginning to wither, and leaving the rest to bear fruit, after thus clearing away all superfluous incumbrances. The only nutriment they give it is this exemption from frequent pruning; but unless the soil should happen to be a very rich one, the vine, under such a method of cultivation, will very soon degenerate to a wild state.
The vine that is thus trained requires the ground to be ploughed very deep, though such is not the case for the sowing there of grain. It is not customary to cut away the leaves in this case, which, of course, is so much labour spared. The trees themselves require pruning at the same period as the vine, and are thinned by clearing away all useless branches, and such parts as would only absorb the nutriment. We have already[3164] stated that the parts that are lopped should never look north or south: and it will be better still, if they have not a western aspect. The wounds thus made are very susceptible for a considerable time, and heal with the greatest difficulty, if exposed to excesses of cold or heat. The vine when trained on a tree enjoys advantages that are not possessed by the others; for the latter have certain fixed aspects, while in the former, it is easy to cover up the wounds made in pruning, or to turn them whichever way you please. When trees are pruned at the top, cup-like cavities should be formed[3165] there, to prevent the water from lodging.

Stays, too, should be given to the vine for it to take hold of and climb upwards, if they are taller than it. (24.) Espaliers[3166] for vines of a high quality should be cut, it is said, at the Quinquatria,[3167] and when it is intended to keep the grapes, while the moon is on the wane. We are assured, moreover, that those which are cut at the change of the moon, are exempt from the attacks of all insects.[3168] According to another system, it is said that vines should be pruned by night at full moon, and while it is in Leo, Scorpio, Sagittarius, or Taurus: and that, in general, they ought to be planted either when the moon is at full or on the increase. In Italy, ten workmen will suffice for one hundred jugera of vineyard.
