Making the Most of Limited Space / Cheap Chinese Junk

Making the Most of Limited Space / Cheap Chinese Junk

So I'm attempting to expand a couple of raised beds in my back yard, but unfortunately there's a huge palm..yucca..thing in the yard that cuts off a good amount of sun, not to mention a pecan tree. So what can I grow there that will tolerate partial shade, and take the heat of a Houston summer? Would potatoes work? How about cowpeas? I loves me some fresh cowpeas! So much better than dried. Even shelling them, I enjoy doing that. I'm crazy. I'd also like to hear some ideas on companion planting. At the moment I have tomatoes, okra, summer squash, a little sweet corn, green beans and many different peppers going. Also.. Cheap Chinese junk. We're not talking boats here. We're talking tools. I had a hoe break on me already. So where can I find good quality, durable tools that haven't been made by the economically disadvantaged? I'm looking for cultivating tools that work well with the heavy sand and clay soils we have here.
