Washington State: Geology and Climate

• AgWeatherNet –  The source for Washington State weather data.
• Geologic Map of Washington (ZIP) – 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?

Soils

• Web Soil Survey: Natural Resources Conservation Services (NRCS) has a web soil survey with interactive and searchable maps.
  • Video – How to Use the Web Soil Survey
• Understanding Soil Surveys – NRCS webpage on the ins-and-outs of reading and understanding soil survey maps.
• Soil Surveys by County: Washington – NRCS webpage with archived information on county soil surveys.
• Soil Testing and Remediation –  See “Soils and Nutrition” for more information

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

The Clean Plant Center Northwest maintains a list of Washington and Oregon Nurseries who cell certified vines.  This list is not exhaustive, but is a good starting place to determine where to source plant material.   Please see the opening statement at the top of this page regarding WA quarantines and regulations relating to the import of out-of-state grapevine materials.

• Clean Plant Center Northwest– Check out the current availability of different varieties in the Washington State Grape Foundation Block. Nurseries have top priority in purchasing plant material from the CPCNW, but in many cases, they are able to accommodate smaller private orders if sufficient plant material is available.
• National Grape Registry – A great database out of California of different grape varieties and clones available in the USA. This is not a source of plant material, but may help you locate a nursery that cells a certified version of the variety or clone you are looking for.
• 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.

Grape (Scion) Varieties

• Vitis International Variety Catalog – A searchable database of different varieties, and their various synonyms.
• WESTERN WA – Growing Winegrapes in Maritime Western Washington – WSU #EM068e
