Growing Grapes in Your Backyard
Grapevines do best with full sun - about 7 or 8 hours per day. Less light leads to lower fruit production, poorer fruit quality, increased powdery mildew, and fruit rot.
How much space do I need?
Spacing between rows can be as little as 8 ft. apart where soils are marginal and up to 12 ft. for wider trellis systems and deep, rich soils. Vine spacing within the row can be 6 to 9 ft. apart. A typical spacing might be 8 ft. apart to accommodate normal growth.
