I had been delaying the over-wintering, when my Scotch Bonnets picked up again. Not sure why, as it's been cold and rainy; however, the pods are growing and ripening, so I am leaving them outdoors (in pots).
Meanwhile, I placed four other pots in the garage, doors open and facing south. I have watered them a few times, but they are barely hanging on. This is where it gets kind of weird - I took the best of the two shishitos (both looked bad) and brought it indoors, placing it in front of a frosty south-facing window. It began producing blooms and now has a nice pod. So I brought the other one in and placed it next to it. Nothing special yet, but it looks like I'll be eating winter peppers. If not for the suggestions in this thread, I would have tossed these plants a while back.
