Grow Carignane grapes in full sun where the soil is deep, rich and well-drained. The soil needs to slightly acidic, with a pH between 5.0 and 5.5. Carignane vines can perform well in hot, dry climates.
Plant Carignane grapevines in spring, leaving 6 feet between vines. Water after planting by flooding the area for 30 minutes. Water the vines once a week during summer if no rain occurs during the first year. Reduce the amount of water after the vines become established after their first year in the ground.
Pound one or two sturdy plant stakes into the ground on opposite sides of each vine, 4 to 6 inches away from the base of the vine. Tie canes to the stake when they grow to about 12 inches long. Use nursery tape or cloth strips rather than wire to prevent damage to the succulent new growth.
Fertilize Carignane grapevines once in spring, using animal manure, organic compost spread as a mulch or commercial fertilizer having an N-P-K ratio of 10-20-20. Follow the fertilizer's label directions for application details.
Prune vines during their winter dormant season. It's OK to prune them severely because grapes will form on new growth the next summer.
