I have a rooftop container garden, and this is the second year that I am trying to grow a determinate hybrid variety called "Best Boy" from seed. None of my other tomato plants suffer from blossom end rot, but this variety cannot produce tomatoes without the bottom turning brown (and I have to pick them off while still golfball-sized). I water deeply every morning, have both granular and soluble fertilizer (at appropriate times), amended soil with ground egg shells, and have hardwood mulch over the soil. I honestly cannot remember if I got any tomatoes last year without blossom end rot. I am baffled why every tomato is getting blossom end rot and concerned because it is determinate--is it the variety or is it me? How much longer should I give it before tearing it up and replacing it?
