I've grown peppers in containers for 5-6 years in a row, cut them back and overwinter them (if possible) they are a very successful perennial if you keep them from freezing.. and will get huge !!
I have never considered peppers as perennials. I live in northern Minnesota and, obviously, plants freeze in the winter. I always thought pepper plants were annuals. If I grew peppers in 5 gallon buckets, could I cut them back in the fall and store them in our basement until the next spring? Seems like I might get a stronger plant if they grow every year rather than planting a new pepper plant. Are all pepper plants perennials, or select varities? Thanks.
