Survival in -40 C of a trough garden?
Hi - I don't know if this would be the best forum for this post but here goes. I have been thinking about creating an alpine trough garden. I have limited space and do do alot of my vegetable gardening in containers. My zone has temperatures going down to -40C in the winter so I wasn't certain if plants would overwinter in a trough container. Any experiences out there?
Sorry that I double posted into the container forum but then I saw this topic.
