I just finished prepping my pepper plants for
overwintering. This is often what I consider the last gardening task of the year. People are often surprised when I tell them that I have pepper plants that are a decade old. Many varieties of peppers grown from seed never have a chance to produce prolific fruit in the climate here. Doing this allows you to get a jump start in subsequent seasons.
This process is fairly easy.
I plant most of my peppers in containers. As soon as the threat of night time temperatures drop below 50 consistently, I start thinking about moving them. First step, blast them with a high powered stream of water to remove any pests that might be hanging on. Bring them inside, and if they still have fruit (and you have space), put them in a warm, lighted spot until you can harvest everything. After this occurs, cut them down to next to nothing and move the
containers to an unheated garage or some other spot that maintains temps around 50 degrees F. You don't really need direct light here and you can water them lightly once or twice a month. Reverse this whole process shortly after your last frost to prepare them for going back outside.
