I have my tomatoes in pots on my deck. I've been noticing many of the hanging ones though. To my surprise, most of them have only a few flowers and even fewer tomatoes. My 4 potted plants have about 15 tomatoes on them. It could be different varieties of plants are maturing at different rates. I do know that I've been housesitting for two different families this week. Both of the upside down plants. I've gotten soaked more than once trying to water the stupid things.
