I have started a garden in Florida where I retired. I have no experience with growing things in central Florida. I planted tomatoes on March 8. I fertilize with Miracle Grow for Tomatoes. I have huge, bushy, dark green beautiful plants. I do not have lots of buds & only a few tiny tomatoes. My neighbors have less healthy looking plants with lots of tomatoes. Could I be giving them too much nitrogen? If so what fertilizer would you recommend?
