I've always had great luck with peppers. Last year, the plants grew so big that the dead ones were still there and were solid enough to use for kindling. But this year, the plants just aren't growing. Most of them seem ok, a few are yellowing, but mostly they just aren't growing. They're blooming, some even have peppers growing on them, but the plants are only 6-10" tall. The plants are in the same dirt I used last year, and I used composted chicken manure and kitchen scraps, same as always. Anybody have any ideas?
