Hot off the Presses -- WSU Extension Publication FS703e - "Idling Vineyards in the Pacific Northwest". 🍇 👨‍🌾

https://pubs.extension.wsu.edu/product/idling-vineyards-in-the-pacific-northwest/

We know the discussion on idling vineyards can be a difficult one to have on-farm, and we hope this guide provides some science-backed references and resources to help you with that discussion and decision-making.

This was a collaborative effort with Patty Skinkis (Oregon State University) and Markus Keller (Washington State University).

WSU College of Agricultural, Human, and Natural Resource Sciences, Oregon Wine Research Institute- Oregon State University, Washington State Grape Society, Washington Winegrowers

Idling a vineyard is not a choice most growers would like to make, but it can be a necessity for long-term business survival. From pruning and irrigation to pest management, there are several ways to reduce vineyard inputs while still maintaining vine health and vineyard viability for the future.
