Grapevines are a hearty plant that--when given the proper conditions--can thrive for over 100 years. Grapevines require full sunlight and high temperatures to completely ripen and produce fruit; they prefer well draining soil. Check with your county extension office to verify the best varieties for your area. This will ensure you avoid weak or disease-prone varieties.
Test the soil for its pH level. Grape plants prefer an acidic soil with a pH of between 5 and 7. If your pH is above 7, sprinkle the entire area with 2 inches of coffee grounds and till it into the soil to a depth of 6 inches.
Check the soil's absorbency. Dig a 1 foot hole and fill the hole completely with water. If the water stands in the hole for more than 30 minutes, the soil is not absorbent enough for grapevines. The soil can be enhanced by mixing in course sand to a depth of 3 feet.
Observe the area throughout the course of the day. If the area receives at least 8 hours of direct sunlight, it is an excellent location for grapevines. Anything less will not provide the plants with ample sunlight for growth and fruit production.
