Rotation with only two beds?
I've just created two raised beds, each 4 feet by 4 feet. I've designated one for brassicas and the other one for the rest. I'm a bit worried that a two year rotation won't be enough to keep down pests/diseases. Any experience? I don't want to use less than one complete bed for brassicas, as I want to grow Chinese veg (Kailan, etc.) in addition to purple sprouting broccoli.
