I had one come and go without fruits... but apparently unless you have bees in your garden, otherwise you have to self pollinate the flowers..
Blur Ting, My first attempt was not successful. I asked around and someone told me burying bones under the tomato plant help. The second time I planted tomato, I bury oyster shells. It seems to have worked. I also used organic fertilizer. I have posted photos of my tomatoes recently.
