Answer: You bet there is! There's a wonderful group of Master Gardeners in the Portland area. They conduct plant problem clinics and answer all kinds of gardening questions. They have educational seminars and are a terrific bunch of volunteers, if you just want to hang out with them and absorb their knowledge. Contact OSU Multnomah Cooperative Extension, or visit their websites: http://extension.oregonstate.edu/mg/
Best wishes with your new garden!
