Renewing Old Vines
Should a vine become old and feeble, it can be renewed by layering. The vine is prepared in the following manner: Prune all the old wood away, leaving but one of the most vigorous of your canes; then dig a trench from the vine along the trellis, say three feet long, eight inches deep; into this bend down the old vine, stump, head and all, fastening it down with a strong hook, if necessary, letting the end of the young cane come out about three eyes above the ground, and fill up with rich, well pulverized soil. The vine will make new roots at every joint, and become vigorous, and, so to say, young, again. Some recommend this process for young vines, the first year after planting; but if good plants have been chosen and planted, it will not be necessary. Feeble and poor plants may need this process, but if plants have good strong roots when planted, (and only such should be planted when they can be obtained), they will not be benefited by it.
