I have raised beds. I put a
fence post on each end and run a wire fence through the middle of the bed. It's about 8' fall, the peas climb up it on there own. When the peas are done I grow melon, cucumber, and beans up the fence
trellis. I'm a home gardener, so I grow on a much smaller scale. I put bush peas in one bed, but they are so much harder to pick, and the verity I planted isn't as good as the tall ones. Probably wont plant them next year. I live in California, so if I don't plant my peas in fall, or late winter it's too hot to grow peas. Saving seeds is a good idea, maybe I will try that too. Thanks
