Gardeners have a range of choices in amounts and intervals for irrigation, depending upon conditions and level of fruit production. Even then a late frost may cause trouble. Spade or rototill an area two to three feet in diameter and at least eight to ten inches deep to loosen the soil. If the soil is sandy, spade in three to four inches of organic matter. Pick a spot with more than eight hours of sun and sheltered from strong winds when possible.
Rows running north-south allow more access to the sun.
Homeowners may also grow grapes on trellises, fences and buildings. South and west exposures along walls and fences are best for sun and fruiting, but are also very hot and require extra care to irrigate to avoid water stress to the plants. As yet, planting European varieties of grapes for wine production is not recommended for home hobbyists in this area. Most homesites do not have suitable or sufficient area for the forty or fifty vines required for home wine making. If you do plant grapes for wine, plant the same variety, or at least grow those that have identical ripening dates.
