You can move the pepper plants indoors when it gets too cold. They do make an attractive houseplant. Pot them up in a larger pot with new potting mix, move them to a nice sunny warm place and keep well watered. Move them back outdoors in May and they will continue producing peppers for you: sooner & more abundant!

No pruning needed: that just reduces the crop.
