I doubt that it gets much hotter there than here in central S.C. with our 90-102 degree July and August days. I find that most any summer crops can be grown into July and August, but many of the things like squash and cucumbers will only do well when planted on the east side of a building or shady tree. Also, you can take part of your garden area and construct a pergula for hanging shade cloth. Get rid of that afternoon sun, and succession crops of green beans, cucumbers, squash, zucchini, tomatoes, and more can keep going. I plant some egg plant and peppers in containers, and move them to a morning sun only spot sometime in June. Cucumbers, squash, and green beans are good candidates to be planted late August or early September for a two or three week harvest in October and sometimes into November.
