Mine are going Nutso!!!!!! I plant mine in pots also. I don't use fertilizer. THe one thing I do is if there are no holes in the bottom of the pot, the plant will drown. I water my plants once a day or maybe once every two days, depending on our weather, realizing of course, that tomatoes are almost water!!! I have BEtter Boys and grape and Sweet 100's. Been eating the grape and 100's for about three weeks now.
I wish you good luck, but you should have had the flowers and the little green tomatoes by now. I have mine planted facing west, so they only have the afternoon sun and that's the hottest and the brightest. Sometimes I think it would be really neat if we could turn into whatever and see what they need and then feed them. Edie
