I thought I had a handle on the BER thing. But now I am not sure what's going on out there. I threw out a bunch of half-rotten "greenies" earlier this month but everything else looked fine. Now we are finding that every tomato that is turning has BER, too. And many of them, as soon as they started to show a little color, I checked the bottoms and they looked fine then, but not now. I am SOOO bummed. So can anyone tell me at what stage BER normally shows up? We have now tossed at least 3 dozen tomatoes.
