Answer: Tomatoes need lots of sunshine and while they like warm temperatures, anything over 90F will either keep them from flowering or will render the flowers sterile. So if your plant flowered but didn't set fruit it may have been the summer temperatures or it may have been that insects couldn't access the plants to pollinate the flowers. If your plant grew but did not flower, it was either getting too much nitrogen fertilizer or not enough sunshine. Hope this information will help you determine just why your plants did not set fruits. Better luck next time!
