This a Roma tomato plant that I planted on the same day as the other plant and it has been producing nice-sized and juicy tomatoes.
Side by side shot of the good tomatoes and the bad tomato.
Shot of the bad spot on the bad tomato; Mom told me as well as several other people to just cut it off and other good tomatoes would begin to grow. No other tomatoes have grown on this plant, just the bad one. As you can see from the picture it's beginning to get ripe.
