| Winter injury |
| Extreme winter temperatures can cause winter injury to vine tissue. Some of the less hardy varieties grown in Michigan may begin to experience damage at 0 degrees F. The extent of damage due to cold temperatures depends on the variety grown, the timing of cold period relative to plant development, and on the weather prior to and immediately following the low temperature episode. This map shows the average number of days per year with temperatures less than -4 degrees F. More information on quantifying risk of winter injury is included in Extension Bulletin, Vineyard Establishment I E-2644 - view text, ordering information. Detailed, long-term weather information is available for 83 sites in the state is available at: http://www.agweather.geo.msu.edu/agwx/index.html |
