I think I may have planted in a bed that was too nutritious (solid cow manure), or so I have been told this might be the cause. They started off looking really good, but eventually the tops would turn brown and shrivel up. Flowers never developed into fruits. I had the same problem with eggplant, but tomatoes did fine. All three were planted in the same bed.

Poblano, lemon jalapeno, and orange bell peppers. Rosita eggplant. Such a bummer, but there's always next year.

I never heard that about pepper addiction. I know a few people who are addicted to kale, which I abhor. There are so many tasty greens in the world, why eat the one that tastes like wood?
