Just moved to the south and putting in a veggie garden?

I had a young man dig a 10'x10' area in the sun, he roltatilled good earth in. I bought some haystraw and started making furrows. I have lots of squash, carrots, beets, radishes, corn, watermellon and so on. I have never worked with such clay earth before (red clay). I did have a 75'x25' garden in the high desert in Ca but the south is so different I was hoping for any suggestions. I am blending the haystraw into the furrows as the rain has been less than average and was told this was best. Any help is appreciated. Thanks. oh, anything else that grows well here?

Well, I live in Lawrenceville,GA. Oh lord knows I have the worse red clay ever!! I have planted so many damn vegetable s but nothing works. But it seems like you got some good earth in there. I am pretty sure the watermelon with grow. Cause that's the only thing that grew in my garden. And go with cow manure. It works
Reply:Gypsum is good to work into the soil and peat moss.
