Can anyone tell me what happened. Last year I planted watermelons and tomatoes. I had so many tomatoes and watermelons that I did not know what to do with them. This year I attempted to grow the same thing and watermelon vines did not grow very well and gave me only two small watermelons. The tomatoe plants produced only a few tomatoes. I fertilized and watered the same as I did the year before, but had an awful harvest. Can anyone help? What should I do next time.
