2. Site Selection and Soil Preparation

Choosing the right location is crucial for successful grape growing.

• Sunlight: Grapes need at least 6-8 hours of direct sunlight per day. Select a site that receives full sun exposure.
• Drainage: Grapes don’t tolerate wet feet. Choose a site with well-drained soil or amend the existing soil with compost or sand to improve drainage.
• Wind Protection: Strong winds can damage grapevines. Consider planting near a fence, wall, or other windbreak.

Soil Preparation:

• Test your soil: A soil test will reveal any nutrient deficiencies or pH imbalances that need to be addressed.
• Amend the soil: Add compost, manure, or other organic matter to improve soil fertility and drainage.
• Remove weeds and debris: Clear the planting area of any weeds or debris that could compete with your grapevines.

3. Planting Your Grapevines

• Timing: The best time to plant grapevines in New Jersey is in the spring, after the last frost.
• Spacing: Space your grapevines 6-8 feet apart to allow for proper growth and air circulation.
• Planting depth: Plant the grapevine so that the root ball is level with the ground.
• Water thoroughly: After planting, water your grapevines deeply to help them establish roots.

4. Training and Pruning

Training and pruning are essential for grapevines to grow strong and produce high-quality fruit.

• Training: Train your grapevines to a specific system, such as the four-cane Kniffen system, to maximize fruit production and make harvesting easier.
• Pruning: Regular pruning is necessary to control growth, remove diseased or damaged wood, and encourage fruit production.
• Winter Pruning: Prune your grapevines in late winter or early spring before bud break.
• Summer Pruning: Remove any shoots that are growing vertically or interfering with the main branches.

5. Watering and Fertilizing

• Watering: Grapes need regular watering, especially during dry periods. Water deeply and infrequently to encourage deep root development.
• Fertilizing: Fertilize your grapevines in early spring with a balanced fertilizer. A soil test will help you determine the specific nutrients your vines need.

6. Pest and Disease Control

• Common Pests: Grape vines can be susceptible to pests like Japanese beetles, grape leafhoppers, and grape berry moths.
• Common Diseases: Diseases like powdery mildew, downy mildew, and black rot can affect grapevines.
• Prevention: Use disease-resistant grape varieties, practice good sanitation, and rotate crops to minimize pest and disease pressure.
• Treatment: If necessary, use organic or chemical treatments to control pests and diseases.

7. Harvesting Your Grapes

• Timing: Grapes are ready for harvest when they reach their peak ripeness. The color, sweetness, and texture will vary depending on the variety.
• Harvesting: Cut the grapes from the vine with a sharp knife or pruning shears. Handle the grapes gently to avoid bruising.
• Storage: Store fresh grapes in the refrigerator for up to a week.
