I'm having the same problems with my tomatoes too. I live in Daytona Beach and was wondering if not having any bees to polinate my vegs is part of the problem. All of my squashes, cukes or any vine that I plant, I maybe get 1 piece of fruit and then the vines don't produce any more- its very frustrating when you put all that work into planting vegs and not to have them produce fruit. I use my own composite, water and feed them, but have hard time growing anything. Any help would be appreciated.
