Growing Grapes in Your Backyard
|Topic||What are the sunlight, soil, and space requirements for a backyard vineyard?|
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. Grapevines will grow and produce well on a wide range of soil types, but good drainage is very important. Roots tend to grow deep – up to 15 ft. deep, although most of the roots grow in the top 3 feet of soil. Therefore, soils should be at least 3 or 4 feet deep above hardpan, stratified layer, or rock, although with careful management, 2 feet of soil can be adequate.
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.
