Shani,
peppers are perennials, so if they are in a pot, you can just bring the pot inside. If your
peppers are in the ground, you can dig them up and pot them. I've done this a couple of times, with some success. I have two
pepper plants on my patio from last year. I didn't think they were going to make it because they got spider mites, and white fly over the winter, but they recovered just fine, and are bearing quite well.
peppers like heat, so if your home is too cold, they may not
flower. If you do get them to
flower, you will have to pollinate by hand or turn a fan on to blow the
flowers around for pollination. Any fruit you get is probably going to be smaller than what you get over the summer, but it's fun to try.
Once it really warms up in late
spring, you can bring them back outside and get a head start on the
pepper growing season.
Good luck.
