The Finger Lakes area is preparing for a major cold wave this weekend, with temperatures forecasted to fall to 10°F or lower. Vinifera grapevines generally have bud hardiness ranging from -5°F to -15°F, making this an ideal time to ready and protect your vineyard. Although grapevines are naturally resilient, extreme cold can test their durability and may harm dormant buds. Here’s how to protect your vineyard and assess vine health after the freeze subsides.
1. Proactive Steps to Protect Vines from the Cold
Insulate the vine base: Applying a thick layer of mulch, like straw or bark, around the vine’s base can buffer against sharp temperature drops. This stabilizes soil temperature and shields the root zone.
Build up soil around graft unions: For grafted vines, piling soil over the graft site provides extra protection against harsh conditions and safeguards this essential part of the plant.
2. Checking Bud Health After the Freeze
Once temperatures rise again, it’s vital to assess the effect on your vines. Here’s how to check bud viability:
Collect canes for inspection: Choose samples from various vineyard areas, including those most exposed to wind and frost-prone spots.
Warm samples indoors: Let the cuttings reach room temperature before inspecting for damage.
Examine the buds’ interiors: Use a sharp blade to slice horizontally through the buds to check their internal state. Healthy buds will have a vibrant green core, whereas damaged ones will appear brown or black.
3. Actions if Damage Is Detected
Evaluate the extent of loss: If only some buds are affected, secondary or tertiary buds might still yield fruit.
Adjust pruning practices: In significantly damaged areas, consider leaving more buds on the canes to offset any productivity loss.
Enhance recovery in spring: Boost vine health by modifying fertilization or irrigation plans to promote growth from surviving buds.
Final Thoughts
Winter weather is an unavoidable aspect of viticulture in places like the Finger Lakes. By preparing your vineyard for freezing conditions and quickly assessing the impact, you can reduce setbacks and support your vines throughout the rest of the dormant season. Careful attention now will pave the way for a successful growing season ahead.
