Answer: I wonder if you are planting at the wrong time of the year? If you've amended your soil with organic matter, and are careful to water and feed, the only other element that might affect a plant's growth is the climate. In Florida you have two opportunities during the year to plant tomatoes, eggplants and peppers. February or August. Why not try planting again in August so the plants can produce during the cooler months of September, October and November? Here's a publication that might be of help to you: http://edis.ifas.ufl.edu/VH021
It is from Florida State University and lists the optimal planting times and best varieties for your local gardening region. Hope you find it helpful!
