Cold Hardiness Monitoring - Back again for 2022-2023!
WSU Viticulture will continue with grape cold hardiness monitoring for the 2022-2023 winter season. Observed cold hardiness data for the Prosser, WA area is updated approximately every 7-14 days at: https://wine.wsu.edu/extension/weather/cold-hardiness/
This webpage also has several resources on preventing cold damage and how to respond after cold damage has occurred.
Given cold hardiness monitoring cannot be done on a large scale, a cold hardiness model is available on AgWeatherNet. You do need a (free!) registered AgWeatherNet Account to see the model: http://weather.wsu.edu/
With the forecast low temperatures for this week dipping to levels that may cause damage, use the model on AgWeatherNet to help prioritize which locations, and varieties, you should start with for follow-up scouting. The resources available on the WSU Grapevine Cold Hardiness Monitoring page above can be used to help you develop a bud collection and assessment plan. They also provide worksheets to develop pruning strategies to compensate for potential crop loss, should cold damage occur.
