Okay I have a question for all. Would an unheated garden shed be like an unheated garage minus the car????????????/ I would think so but I'm holding out to say what others think and why before I put my brugs out there. They did fine for me in the unheated garage one year. Even though the top growth did die and I panicked and had a double hissy fit . I cut them down and they came up from the roots real fast and tall....................................
