Seedless grape (Vitis vinifera) varieties grow in U.S. Department of Agriculture plant hardiness zones 4 though 9, depending on the cultivar.

How to Reproduce Seedless Grapes

by Julie Richards

Seedless grape varieties can be propagated for the vineyard by several methods. It's not possible to grow them from seeds, so growers use grafting, cuttings and tip-rooting techniques. For the home garden, cane cuttings have a good success rate for vine reproduction. The cuttings are made from healthy canes that are 1 year old.

1 Choose canes that are at least 1/4 inch thick and are free from disease or pest infestations. Count down six buds from the end of the cane, and make a straight cut just below the sixth bud with a pair of sterile pruning shears. Make a diagonal cut at the tip of the cane to differentiate between the top and bottom of the cutting.

2 Moisten sphagnum moss with clean water and squeeze the moss to remove as much of the water as possible. Lay a piece of burlap on a flat surface and cover the cloth with the moistened moss. Place the seedless grape cuttings on the moss with the diagonal cuts oriented the same way. Fold the burlap over the cuttings to form a small bundle. Tie the burlap into place with garden twine.

3 Dig a trench in the garden that is about 6 to 8 inches deep, and long enough to lay the bundle flat. Cover the bundle with soil. Mark the area with a garden marker. For cold-weather climates, cover the area with a layer of mulch, such as straw, hay or dried leaves, to protect the cuttings during the winter chill.

4 Remove the bundle in the spring. Plant the cuttings so the top bud is exposed above the soil surface. Space cuttings at least 6 inches apart. Water the cuttings deep enough that the bottom node gets moisture. Grow the canes out for 1 year. Transplant the new seedless grape vines where you want them the following spring.
