I am planning to grow as much feed as possible for my goats-2 milking does and a buck. Full sized nubians. At this point the plan is to grow mangel beets, timothy grass, clover, alfalfa and try our hand at a short season sunflower. We are in SE Alaska which has long days during the summer, gets a lot of rain, but doesn't get very cold-or very warm for that matter. Any tips about the types of plants that would do well in a cool rainy area? Think Seattle area on steroids.
