I did container gardening all summer long this year. I had a lot of ups and down and learned that the larger the container the better, otherwise it will lead to sporadic watering. Winter is here in Wisconsin and I am still growing my pepper plants in the greenhouse i have. I made a video about repotting, overwintering and pruning.
