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.
I did it one year with jalapeños and will likely never do it again. The yield on them was actually less than the freshly planted. I think the winter just over-stressed the plant and it never fully recovered. Zone 8a.
