I just heard on the PSWG email list that Gary Moulton is teaching a series of grape growing class specifically for Western Washington in 2015. Gary is a long time fruit expert in Western Washington and was once in charge of the grape program at WSU Mt. Vernon. There isn’t anyone that knows as much about taking care of your vines in the Puget Sound AVA as Gary. Looks like a great series of class timed for the time of year the class is given. Classes are in Bow, WA in the Skagit Valley. They are between $45 and $40.
You can find the class and sign up at the WSU Snohomish County Extension website at: http://ext100.wsu.edu/snohomish/vineyardcare/
