Zone 7a, Kentucky USA. I read about over-wintering peppers and tried it out last year, but sadly none of them survived. I pruned them appropriately, and kept them in my garage with infrequent watering once temperatures started getting into the 40s at night. We had wild temperature fluctuations (high 60s F during the day and low 30s F at night) and I’m not sure if that hindered the process.
I would love to try again this year, but I’m wondering what others’ experiences are.
My aunt is a big gardener in 7a (piedmont NC) and has overwintered jalapenos a few times and declared it not worth it for her, apparently the yields aren’t much/any bigger than new seedlings and it’s a nontrivial amount of work and space to keep them overwintered. If you try again and have different results I’d love to hear about it!
