Handling and preparing the vines.
ОглавлениеThe better vines are packed, transported and cared for in the field, the quicker will the roots take hold and the vines make the vigorous start on which so much depends. The nurseryman should be requested not to prune much before packing and to pack the vines well for shipping. The vines should be heeled-in as soon as they reach their destination. If the vines are dry on arrival, they should be drenched well before heeling-in. It sometimes happens that the vines are shriveled and shrunken from excessive drying, in which case the plants often may be brought back to plumpness by burying them root and branch in damp earth, to remain a week or possibly two. To heel-in, a trench should be double furrowed in light, moist soil, the vines spread out in the trench two or three deep, and then earth shoveled over the roots and half the tops, sifting it in the roots, after which the soil is firmed. The vines may thus be kept in good condition for several weeks if need arises.
The vines are prepared for planting by cutting away all dead or injured roots and shortening-in the healthy roots. Grape roots can be cut severely if healthy stubs remain, the removal of small roots and fibers doing no harm, since fibers are of value only as indicating that the vine is strong and vigorous. Fresh fibers come quickly from stout, healthy roots. Most of the fibers of a transplanted vine die, and laying them out in the hole to preserve them, as is so often recommended, is but a useless burial rite. On good healthy vines, the stubs of the roots, when cut back, will be four to eight inches in length. The root system having been considerably pruned, the reciprocity between roots and tops must be taken into account and the top pruned accordingly. To reduce the work of the leaves to harmonize with the activities of the roots, the top should be pruned to a single cane and two, never more than three, buds. The vine is now ready for planting and, the soil being in readiness, planting should proceed apace.
