Cuttings are made from one-year-old wood; that is, canes produced during the summer are taken for cuttings in the fall. Immature canes and those with soft, spongy wood ought not to be used. Strong vigorous canes should be given preference over weak growth, but most nurserymen maintain that very large canes do not make as good cuttings as do those of medium size, the objection to large size being that the cuttings do not root as well. Short-jointed wood is better than long-jointed. Cuttings from vines weakened by insects and fungi are liable to be weak, soft, immature and poorly stored with food. The wood should be smooth and straight.
