I live in Pontiac, MI, on the border of zones 6a and 5b, and something strange is going on with my peppers... they're not dying. Well, a couple are in the process of withering, but my other 250 plants are still producing after several frosts, and a couple of 30s-40s rains. My nephew (also in MI) has this issue as well, with his tomatoes. All I'd like to know is what the heck is going on?
