Grape vines can be propagated quite successfully from hardwood cuttings. Propagating vines in this manner produces a new plant that is genetically identical to the parent vine. This is particularly valuable in the propagation of heirloom plants and older hybrids, but growers should be aware that many new varieties are patented and propagation may be prohibited or require a license. Only small sections of vine are needed and can be taken from pruned branches. Rooting hormone is not recommended. If cuttings are taken in the early spring, vines can be ready for the vineyard by the following fall.
Cut vines for propagation during the dormant season, in the early spring before new growth appears.
Choose a healthy, vigorous vine. Cut sections of vine just below a bud or node. Leaving three nodes on the cutting, cut again at a 45-degree angle about 3/4 inch to 1 inch above the third node. The resulting piece is a short piece of vine with three nodes, a flat cut at the bottom and an angled cut at the top
Plant the cutting into a pot of moist soil, burying the flat end and bottom node, leaving the second node at soil level.
Place the cuttings indoors or in a sheltered location and supply as much humidity as possible, either by misting several times a day or locating the pots near a humidifier.
Water the rootings to keep the soil moist, but not wet, until the vines have taken root.
Move the plants outdoors to a shady location after the roots are established and the weather is above freezing. Keep the new vines moist and protected from direct sunlight.
Transplant the new vines to the vineyard once they have hardened off and adjusted to the outdoor weather.
