Chili/hot
peppers grow well in pots, I grow my extras in pots, and
flower boxes.The smaller fruited types do better, like Thais or edible ornamental types. I did overwinter, a Tabasco, and a Lemon Drop Aji from last year- both are alive still! Hot
peppers actually will live a longtime if not subjected to freeze or frost, in fact in tropical and warm countries, they can grow into woody bushes or small trees!
I use regular 3 foot long plastic planter boxes, and the
peppers do well. You just have to water more regularly with pots, as they have the tendacy to dry out fast, especially in warm weather. You can mix or match different peppes for color effect or personal taste.
