I have been growing this Musa Basjoo plant from a small pup for about three years. It is now 6 feet. This was the first year that I will not be able to bring it inside the house for the winter.

It is just too large. I have been told that these plants will grow back if the trunk is cut, but I don't have the heart to do that UNLESS I HAVE TO. Any advice on how to care for the plant in zone 6 usa, where the winters can be very harsh, even with hardy bananas as the musa basjoo? I have seen trees that are cut return, but never plants in pots. I do not know what to do with this lovely happy plant during the cold months. ***Should I cut it?***
