At first it seemed like a roaring success as the plants grew vigorously then quickly set fruit. But then all of sudden the plants succumbed to attack by both bacteria and some leaf eating pest. In contrast a summer variety planted in the garden at the same time has set less fruit but seems far more promising as the plants are still strong and lush. Everything is an experiment and it may turn out that growing winter tomatos is just a waste of time and garden space for us, as another crop may produce more for us over winter.
