Will a tomato plant sprout fruit on its own or does it need another tomato plant close by to pollinate the flower to produce fruit? My plants are about 3-4 feet high, but have failed to produce any fruit and are planted one in the garden and one on my deck.

You may also have an issue with poor pollination, which you can remedy by hand pollinating.
