If the vine is to be trained to grow without any stay at all, still it will stand in need, at first, of some support or other, until it has learnt to support itself: in all other respects the mode of proceeding will be the same at first. When pruning, it will be necessary that the thumb-branches should be arranged in equal numbers on either side, in order that the fruit may not overload one side of the tree; and we may here remark by the way, that the fruit by its weight is apt to bear down the tree and counteract any tendency to increase in height. The vine, unsupported, when more than three feet in height, begins to bend, but the others do not, until they are five feet high at the least; care should be taken, however, never to let them exceed the height of a man of moderate stature. Growers are in the habit of surrounding the vines that creep along the ground with a low fence for them to lean upon; and round this fence they dig a trench by way of precaution, for fear lest the branches in their range should meet one another and so come into collision. The greater part of the world, in fact, gather grapes at their vintage, grown in this fashion, and lying upon the ground — at all events, it is so in Africa, Egypt, and Syria; throughout the whole of Asia, too, and in many parts of Europe as well, this method prevails. In such cases the vine ought to be kept down close to the ground, and the root should be nurtured at the same time and in just the same way as in the case of the vine that grows on the cross-piece. Care, too, should be taken to leave only the young thumb-shoots, together with three buds, where it is a prolific soil, two where it is poor and thin: it is better, too, that the shoots should be numerous than individually long. The influences of soil, of which we have made mention already, will make themselves felt all the more powerfully the nearer the grapes grow to the ground.
It is a very advantageous plan to separate the various species of vines and to set them in different compartments — for the mixture of different varieties is apt to deteriorate the flavour not only of the must, but the wine even as well. If, again, for some reason or other, the different kinds must be intermingled, it will be requisite to keep all those together which ripen at exactly the same period. The more fertile and the more level the soil, the higher the cross-pieces must he placed. High cross-pieces, too, are best suited to localities that are subject to heavy dews and fogs, but not to those that are exposed to high winds; on the other hand, where the soil is thin, parched, and arid, or exposed to the wind, the cross-pieces should be set lower. The cross-piece should be fastened to the stay with cords tied as tight as possible, while the bindings used for tying the vine should be thin. As to the various species of vines, and the soils and climates requi- site for the growth of each, we have already treated of them, when enumerating the several varieties of the vine and the wines which they produce.
With reference to other points connected with the culture of the vine, there are very considerable doubts. Many persons recommend that the vineyard should be turned up with the spade after every dew that falls in the summer. Others, again, forbid this practice when the vine is in bud; for the clothes, they say, of the people coming and going to and fro are apt to catch the buds, and either knock or rub them off; it is for this reason, too, that they are so careful to keep all animals away from the vines, those with long wool in particular, as it is very apt to pull off the buds. Raking, too, they say, is very injurious to the vine while the grape is forming; and it will be quite sufficient, they assure us, if the ground is turned up three times in the year, after the vernal equinox — first, at the rising of the Vergiliæ, the second at the rising of the Dog-star, and the third time just as the grape is turning black. Some persons make it a rule that an old vineyard shall have one turning up between the time of vintage and the winter solstice, though others, again, are of opinion that it is quite sufficient to bare the roots and manure them. They turn up the ground again after the ides of April, but before the time for germination, or, in other words, the sixth of the ides of May; then again before the tree begins to blossom, after it has shed its blossom, and, last of all, when the grape is just on the turn. The most skilful growers say that if the ground is dug up oftener than necessary, the grapes will become so remarkably thin-skinned as to burst. When the ground is turned up, care should be taken to do it before the hot hours of the day; a clayey soil, too, should never be ploughed or dug. The dust that is raised in digging is beneficial to the vine, it is said, by protecting it from the heat of the sun and the injurious effects of fogs.
The spring clearing ought to be done, it is universally admitted, within ten days after the ides of May, and before the blossoming begins; in addition to which, it should always be done below the cross-piece. As to the second clearing, opinions differ very considerably. Some think it ought to be done when the blossoming is over, others, again, when the grapes are nearly at maturity. This point, however, may be decided by following the advice of Cato on the subject; for we must now pass on to a description of the proper’ mode of pruning the vine.
Immediately after the vintage, and while the weather is still warm, the work of pruning begins; this, however, ought never to be done, for certain physical reasons, before the rising of the Eagle, as we shall have occasion to explain in the following Book. Nor should it be done either when the west winds begin to prevail, for even then there is great doubt whether a fault may not be committed by being in too great haste to commence the work. If any return of wintry weather should chance to nip the vines, while still labouring under the wounds recently inflicted on them in pruning, there is little doubt that their buds will become quite benumbed with cold, the wounds will open again, and the eyes, moistened by the juices that distil from the tree, will become frost-bitten by the rigour of the weather. For who is there, in fact, that does not know that the buds are rendered brittle by frost? All this, however, depends upon accurate calculations in the management of large grounds, and the blame of precipitation cannot with any justice be laid upon Nature. The earlier the vine is pruned, in suitable weather, the greater is the quantity of wood, while the later the pruning, the more abundant is the fruit. Hence it is that it is most advisable to prune the poor meagre vines first, and to defer pruning the more thriving ones to the very last. In pruning, due care should always be taken to cut in a slanting direction, in order that the rain may run off with all the greater facility. The wounds, too, should look down- wards towards the ground, and should be made as lightly as possible, the edge of the knife being well-sharpened for the purpose, so as to make a clean cut each time. Care should be taken, too, to cut always between two buds, and that the eyes are not injured in the operation. It is generally thought that wherever the vine is black, all those parts may be cut off, the healthy parts not being touched; as no useful shoots can be put forth by wood that is bad in itself. If a meagre vine has not good stock-shoots, the best plan is to cut it down to the ground, and then to train new ones. In clearing away the leaves, too, those leaves should not be removed which accompany the clusters, for by so doing the grapes are made to fall off, except where the vine happens to be young. Those leaves are regarded as useless which grow on the sides of the trunk and not from an eye; and so, too, are the bunches which shoot from the hard, strong wood, and are only to be removed by the aid of the knife.
Some persons are of opinion that it is a better plan to fix the stay midway between two vines; and, indeed, by the adoption of this method the roots are cleared with greater facility. It is best, however, where the vine needs but a single cross- rail, due care being taken that the rail is a strong one, and the locality not exposed to high winds. In the case of those vines which require trellissed cross-rails, the stay should be placed as near as possible to the burden it has to support; in order, however, that there may be no impediment thrown in the way of clearing the roots, it may be placed at the distance of one cubit from the stock, but not more. It is generally recommended to clear the roots before the pruning is commenced.
Cato gives the following general precepts in relation to the culture of the vine:—” Let the vine grow as high a
s possible, and fasten it firmly, but not too tight. You should treat it in the following manner. Clean the roots of the vine at seedtime, and after pruning it dig about it, and then begin to labour at the ground, by tracing with the plough continuous furrows every way. Plant the young vines in layers as early as possible, and then break up the ground about them. If the vine is old, take care and prune it as little as possible. In preference, bend the vine into the ground for layers, if necessary, and cut it at the end of two years. The proper time for cutting the young vine, is when it has gained sufficient strength. If the vineyard is bald of vines, then draw furrows between them, and plant quicksets there: but let no shadow be thrown on the furrows, and take care and dig them often. If the vineyard is old, sow ocinum there, in case the trees are meagre: but take care and sow there nothing that bears seed. Put manure, chaff, and grape-husks about the roots, or, indeed, anything of a similar nature that will give the tree additional strength. As soon as the vine begins to throw out leaves, set about clearing them. Fasten the young trees in more places than one, so that the stem may not break. As soon as it begins to run along the stay, fasten down the young branches lightly, and extend them, in order that they may gain the right position. When the grape begins to be mottled, then tie down the vine. The first season for grafting the vine is the spring, the other when the grape is in blossom; the last period is the best. If it is your wish to transplant an old vine, you will only be able to do so in case it is no thicker than the arm: first, however, you must prune it, taking care not to have more than two buds upon the stem. Then dig it well up by the roots, being careful to trace them, and using every possible precaution not to injure them. Place it in the hole or furrow exactly in the position in which it has stood before, then cover it with earth, which should be well trodden down. You must then prop it up, fasten it, and turn it in the same direction as before; after which, dig about it repeatedly.” The ocinum that Cato here recommends to be sown in the vineyards, is a fodder known by that name by the ancients; it thrives in the shade remarkably well, and received its name from the rapidity with which it grows.
(23.) We come now to speak of the method of growing vines upon trees, a mode that has been condemned in the strongest terms by the Saserna’s, both father and son, and up- held by Scrofa, these being our most ancient writers on agri- culture next to Cato, and men of remarkable skill. Indeed, Scrofa himself will not admit that it is beneficial anywhere except in Italy. The experience of ages, however, hats sufficiently proved that the wines of the highest quality are only grown upon vines attached to trees, and that even then the choicest wines are produced by the upper part of the tree, the produce of the lower part being more abundant; such being the beneficial results of elevating the vine. It is with a view to this that the trees employed for this purpose are selected. In the first rank of all stands the elm, with the exception of the Atinian variety, which is covered with too many leaves; and next comes the black poplar, which is valued for a similar reason, being not so densely covered with leaves. Most people, too, by no means hold the ash and the fig in disesteem, as also the olive, if it is not overshadowed with branches. We have treated at sufficient length already of the planting and culture of these several trees.
They must not be touched with the knife before the end of three years; and then the branches are preserved, on each side in its turn, the pruning being done in alternate years. In the sixth year the vine is united to the tree. In Italy beyond the Padus, in addition to the trees already mentioned, they plant for their vines the cornel, the opulus, the linden, the maple, the ash, the yoke-elm, and the quercus; while in Venetia they grow willows for the purpose, on account of the humidity of the soil. The top of the elm is lopped away, and the branches of the middle are regularly arranged in stages; no tree in general being allowed to exceed twenty feet in height. The stories begin to spread out in the tree at eight feet from the ground, in the hilly districts and upon dry soils, and at twelve in champaign and moist localities. The hand of the trunk ought to have a southern aspect, and the branches that project from them should be stiff and rigid like so many fingers; at the same time due care should be taken to lop off the thin beardlike twigs, in order to check the growth of all shade. The interval best suited for the trees, if it is the grower’s intention to keep the soil turned up with the plough, is forty feet back and front, and twenty at the side; if it is not to be turned up, then twenty feet every way will do. A single tree is often made to support as many as ten vines, and the grower is greatly censured who attaches less than three. It is worse than useless to attach the vine before the tree has gained its full strength, as in such case its rapidity of growth would only tend to kill the tree. It is necessary to plant the vine in a trench three feet in depth, leaving an interval of one foot between it and the tree. In this case there is no necessity for using mallet shoots, or for going to any expense in spading or digging; for this method of training on trees has this advantage in particular, that it is beneficial even to the vine that corn should be sown in the same soil; in addition to which, from its height, it is quite able to protect itself, and does not call for the necessity, as in the case of an ordinary vineyard, of enclosing it with walls and hedges or ditches, made at a considerable expense, to protect it from injury by animals.
In the method of training upon trees, reproduction from quicksets or from layers is the only mode employed of all those that have been previously described; the growing by layers being effected two different ways, as already mentioned. The plan, however, of growing from layers in baskets set upon the stages of the tree is the most approved one, as it ensures an efficient protection from the ravages of cattle; while, according to another method, a vine or else a stock-branch is bent into the ground near the tree it has previously occupied, or else the nearest one that may be at liberty. It is recommended that all parts of the parent tree that appear above ground should then be scraped, so that it may not throw out wood; while at the same time there are never less than four buds on the part that is put into the ground for the purpose of taking root; there are also two buds left above ground at the head. The vine intended for training on a tree is planted in a furrow four feet long, three broad, and two and a half in depth. At the end of a year the layer is cut to the pith, to enable it to strengthen gradually at the root; after which, the end of the branch is pruned down to within two buds from the ground. At the end of two years the layer is completely separated from the stock, and buried deeper in the ground, that it may not shoot at the place where it has been cut. As to the quicksets, they ought to be removed directly after the vintage.
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” 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, 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 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 f
eet 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 ten- drils 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.
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:” throughout the whole of Greece, rushes, cyperus, and sedge 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.
