 How do we overwinter tropical plants in the northeast in a Zone 6? Some would say we're in a Zone 7. That's debatable. Either way, we can't maintain these outdoors, with the exception of we have a fairly large collection of banana plants, which I do overwinter outside. So that's always the question. How do I do this? I'll jump right into that. When I came back here in October 16, it was right around the time of us getting these overwintered.
