I too have clay, and I'm in a low lying area, so have major water in the spring. My vegetable garden is mostly in pots. Its much easier to find flowers for your conditions, so my flower beds look great. I have several compost bins (Rubbermaid w/holes drilled in them) I add table scraps and grass and leaves. I roll them around all summer as I'm adding to them and let them sit all winter. In the spring the compost is glorious! I add it to all my pots and my veggies do great!
