Importance of Clean Plants and Quarantines

IMPORTANT NOTICE: Regardless of whether you are a commercial grape producer or a backyard enthusiast, Washington State has strict quarantines regarding where your grapes come from.  DO NOT bring back grape plants from your trips abroad (whether domestic or international). Doing so may result in very strict fines, but more importantly, may bring in diseases and pests that could severely hurt the commercial grape industry.  ONLY buy stock from reputable nurseries. If you purchase from sources outside of WA, you must notify the Washington State Department of Agriculture of their arrival, and schedule an inspection.  More information on “planting clean” and WA quarantines are found here:

Getting Started

Vineyard Design Considerations

Washington State: Geology and Climate

  • AgWeatherNet –  The source for Washington State weather data.
  • Geologic Map of Washington – A great map that describes the geological features of the state. (link will open a  .zip file from the Washington State DNR).
  • Western Regional Climate Center – Historical information regarding growing degree days, temperature, precipitation, wind speed and directions for a number of locations in the Western United States.
  • Normal Climate Maps for United States – Use this site to get frost/freeze data for the past 30 years, precipitation data, and more through the NOAA.
  • 2012 USDA Plant Hardiness Zone Maps –  Determine the 30-year average absolute minimum temperatures for a particular area.  Is your site appropriate for winter-tender vines?

Variety and Rootstock Selection

Variety selection is dependent on what is best suited for your site and what you can market/sell. Consult potential fruit customers and winemakers before heavily investing in large plantings.

Plant Sources:

  • Clean Plant Center Northwest Grapes – Check out the current availability of different varieties in the Washington State Grape Foundation Block.
  • National Grape Registry – A great database out of California of different grape varieties and clones available in the USA.
  • Grape Genetic Testing and Identification – A service provided by the Foundation Plant Service out of UC-Davis that can determine the variety/cultivar of an unknown grapevine. Clonal identification is currently not available.

 Variety Information:

Rootstock Information: 

  • Rootstock Selection – OSU #EM8882 – Rootstocks are recommended for western Washington, due to general lower soil pH and cooler, shorter seasons. Conditions in western Oregon are similar to Western Washington.
  • Rootstock Selection – Pages 12-15 in: Wine Grape Varieties in California. University of California Agricultural and Natural Resources Publication
