I have found I like American Agriculture in Beaverton for the most useful advice and reasonable prices. They seem more than willing to talk, I just don't say what I'm growing. Seems simple enough, as they know, especially when I say something like, "Help, I'm 5 weeks from harvest and I think I have spider mites!" Good people there. They have a store in SE Portland, but I don't feel as comfortable there.
