The July issue of Wines & Vines also contained an article written by Tony Wolf about Recovering from Cold Injury in Virginia. I read both of the articles with interest because of what we are seeing in our own vineyard.
From both articles, I learned that we are not out of the woods yet with the vines that are currently growing in our vineyard.
- We may still see collapse of some vines that have gone through bud break and begun to develop a canopy due to damage of the regenerative vascular cambium tissue
- We may see an increased incidence of crown gall due to trunk splitting
- Avoid nitrogen fertilization for this season and consider sowing a cereal under the trellis to provide some competition and reduce shoot vigor
- Re-evaluate your training system and make decisions about what should be done differently based on plant survival patterns in the vineyard
- Keep existing plants healthy in order to produce fruitful buds next year
- Rethink varietal planting scheme and replant the block with a variety that is more cold hardy
