My Cherokee purple and my Arkansas Traveler's tomatoes now have small rotten spots on the them before I even pick them. Most of them are only half ripe when this happens. What's going on?
at least you have fruit my Black Siam's have blooms but no fruit. and I would love to know what to do to get them to set fruit.
Knowing your zone would help.
A photo would help. But my first thought is that it might be blossom end rot. Blossom end rot looks like a rotten area that forms on the opposite end of the fruit from the stem. If that's it, just take that fruit off. Another one will grow without it.
They get them on the bottoms and in other places around the tomato. I'm familiar with BER. Just never had it this bad. Are heirlooms more susceptible to it?
