I grow my tomatoes in homemade grow boxes, and have had great success...until this year. The plants were huge and like a jungle, but not too many tomatoes, and now they have a lot of BER. I thought perhaps I had used a fertilizer with too much nitrogen, and that kept the needed calcium at bay. But now a number of other area gardeners are complaining about the very same thing. We had a very hot summer, but other than that, I can't think of why we would have this problem. Any answers out there?
