I'm new to the Forums. We have a place in Coalmont (near Princeton) which although listed is Zone 5 is Zone 3 according to the locals and the Nurseries in the area. The last 2 Winters we have had a week of -35F (-30C) and it can reach -40 (both F&C). Anyone have any comments?
Hi and welcome to the forums - see this thread for a similar thread. At those temperatures, it almost sounds like zone 2!
