Grapevines take three years to establish. After transplanting in the spring, the vine is trained to a stake during the first year. In the second year, the lateral or horizontal branches are trained to the trellis. During the third summer, the fruiting shoots develop and the first small crop is harvested. The first full crop is expected the fourth year.
Prepare well-drained soil for grapevines in a location with full sun. Perform a soil test to determine pH and fertility. Adjust the pH to between 5.0 and 6.0 as needed.
Transplant healthy plants in the early spring as soon as the soil can be worked. Dig a hole large enough to accommodate the roots. Plant the vines at the depth they were originally growing, spreading the roots in the hole and covering them with soil. Plant vines 6 to 8 feet apart along a trellis or fence.
Remove all but the most vigorous cane immediately after planting. Shorten the remaining cane, leaving two strong buds.
Tie the strongest developing cane to a stake when it reaches 8 to 12 inches tall. Remove the weaker cane in the spring of the second year.
Fertilize approximately two weeks after planting with 8 ounces of 10-10-10 fertilizer per plant. Spread the fertilizer on the ground beneath the vine, keeping it at least 6 to 12 inches away from the developing canes.
Mulch below the vines with 4 to 6 inches of organic mulch to discourage weeds and conserve moisture. Pull weeds by hand as they appear.
Water young plants as needed until they are established. Established vines need irrigation only during dry weather.
