Not many things can be as rewarding, or challenging, as growing your own backyard grapes. Below are links to information sources specific for the hobby viticulturist.
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. All plant materials originating outside of WA (whether certified or not) need to be inspected by the WSDA upon arrival; notify the nursery that they need to include an origination certificate (more information below) with the shipment. Just because an out-of-state nursery will ship to you, does not mean it is legal to do so. More information on “planting clean” and WA quarantines are found here:
