A lot of fungal issues from what I have heard of that neck of the woods. Botryitis (bud rot) and Powdery Mildew. Those are most common PNW outdoor problems anyways. Not sure of pest issues around that area. I would look for mold resistant strains or early strains that finish no later than the beginning of October. Where I am, I have to do the same, due to the high PM in my area when the fall hits as well as the Botrytis from how rainy it gets. Best of luck, and if you stick with this site you won't be disappointed with what you can achieve. Welcome to the farm!
