Preventing and Mitigating Low Temp Injury (or Cold Damage) in Grapevines
Grapegrowing Breakout Session

Cold injury is a significant limitation for successful grape production in many areas of North America. Injury may occur in the Fall before vines are fully acclimated, during the mid-winter period when low temperatures exceed the vines maximum hardiness level, and in the Spring when vines are de-acclimating in response to warming temperatures. In addition, significant low temperature injury can occur after vine buds are developing and green tissue is present (frost damage).

An increased number of extreme events, including low temperatures, are predicted to occur because of Climate Change. Information will be presented on practices growers can utilize to avoid or prevent cold injury as well as those that can be used for mitigation when injury has occurred. In addition, growers will provide insight into how they have been impacted by and responded to recent freeze events.
