Follow these essential steps to ensure your grapevines thrive and produce a large, sweet harvest in the fall through proper care and attention.

1. Managing Vine Growth:

  • Remove Stepchildren: Regularly check for and remove stepchildren (suckers) that grow between vine nodes. Use sharp secateurs to cut them close to the main vine, leaving only a small stump (no more than 1 cm). This prevents overcrowding and ensures the vine receives optimal nutrients for fruit development.

2. Training and Pruning:

  • After about 10-12 leaves on each vine, pinch or prune the growth to control vine height. Leave one upper stepchild and trim it to two leaves. Remove excess foliage above grape bunches to allow sunlight to reach the fruits, promoting better ripening and reducing the risk of fungal diseases.

3. Watering Regimen:

  • Maintain Adequate Moisture: During hot weather, ensure each grape plant receives approximately 20 liters of water. Consistent watering is crucial to prevent berries from cracking due to sudden moisture fluctuations, especially after periods of heat followed by rain. Mulching around grape bushes helps retain soil moisture.

4. Disease Prevention:

  • Early Intervention: Grapevines are susceptible to fungal diseases such as powdery mildew, gray rot, and downy mildew. Begin preventive measures when grapes reach 5 mm in size. Use fungicides like Skor, Topaz, or Oxyxum as directed to protect against diseases and ensure a healthy crop.

Conclusion:
By diligently following these guidelines for vine care in July, you’ll optimize grapevine health and promote robust growth, leading to a plentiful and sweet harvest in the autumn. Proper pruning, watering, and disease management are key to maximizing grape quality and yield, ensuring your vineyard remains productive and disease-free throughout the growing season.
