All types of grapes require a warm planting site with full sun and moderate water. Consult with a nursery professional to select a variety that will do well in your area. The soil at the planting site should be loose, rich and deep. The roots of grape vines go deep into the earth. Amend to a depth of 24 to 36 inches with a good organic compost to improve existing soil. PlantCT(TM) System.
