Autumn Tips for Grapes: When and How to Properly Cover the Vine
As autumn arrives, it’s time to prepare your garden for the winter. Grapes require special care, even though they are hardy plants. Many people rush to cover the vines as soon as the first frost hits, but grape growers should be cautious. When should you start, what materials are best, and how can you avoid causing harm to the vine? Let’s break it down.
When to Cover Grapes
The ideal time for covering grapes is when the leaves fall or just as the grape clusters begin to ripen. It’s important to wait for the vines to fully ripen before you start covering them. Why wait? Grapevines are naturally resistant to cold, but premature covering can damage the plant. If you cover them too early, the vines might still be too immature, and this could lead to frost damage.
How to Cover Grapes
The material you choose to cover your grapes depends on your climate and the specific needs of your vineyard. Here are the most popular and effective options:
- Spruce branches: One of the best materials for covering grapes, spruce branches allow the wind to pass through, retain heat, and prevent the vine from wilting.
- Thyrsa: A cost-effective and efficient option. Wrap the vine with a 20-25 cm thick layer of thyrsa, and then cover it with boards or slate to provide extra protection.
- Non-woven materials: Spunbond and other non-woven fabrics are highly breathable and moisture-resistant, protecting vines from frost and drastic temperature fluctuations.
How to Properly Wrap Grapes
Before you cover your grapes, take some preparatory steps:
- Prune the vine, removing any leaves and pods.
- Dry the soil: Ensure the soil around the vine is dry to prevent the growth of fungal diseases.
Now, follow these steps for proper coverage:
- Remove the vine from its support: Carefully detach the vine from the support and gently lay it on the ground.
- Wrap with material: Cover the vine with your chosen material, ensuring a snug fit.
- Secure the shelter: Fix the covering to the ground to prevent it from being blown away by the wind.
What to Avoid When Covering Grapes
- Burying the vine: Avoid burying the vine with soil, as this can lead to damage.
- Using polyethylene: Polyethylene can trap moisture and prevent air circulation, leading to condensation and fungal diseases.
- Covering too early: If you cover the vine too early, the grapes may not fully ripen, and you risk damaging the vines.
Conclusion
Properly covering your grapes will help ensure a healthy winter and a bountiful harvest next season. By following these simple steps and considering your climate and vine varieties, you can protect your vines from the harsh winter months and enjoy a thriving vineyard. Happy gardening!
