Answer: If it hasn't shown any growth at all, it may be dead. You have nothing to lose by unpotting it and checking the roots to see if they're still alive. If so, you can always repot it. A hardy banana is reasonably hardy - for a banana. The foliage will die down if the weather is frosty, but the roots will remain alive - providing they don't freeze solid. I suspect that since yours was in a container, which was above ground all winter, that your freezing weather may have killed them. To prevent this in the future, either bury the pot in the ground (which will help insulate the roots), or wrap some insulating material around the pot to keep the soil and roots from freezing solid. Best wishes with your garden!
