Answer: You may want to change varieties, as some just don't like the south. Select varieties with short days-to-harvest intervals and plant them as early as you can so they mature before it gets too hot. Also, try to keep them harvested before they get too mature.
Finally, try growing beans for a fall harvest. Time your planting to mature before cold weather and frosts arrive. I think the best tasting beans in the south are grown in the fall, when the fruit can ripen in cooler weather.
