Yes, but I don't have much experience doing it that way.

Last fall, I had an 7' Ensete 'Maurelli' in an 18" pot. I decapitated it just above the meristem and put the pot in a cool, dark part of my basement. I expected it to die so did nothing else. In early April, I put it into a warm greenhouse where I start my seeds. I gave it water and fertilizer. Much to my surprise, it grew very fast. I put it outside in the middle of May. It was back to 7' by the end of June.

Thanks! I'm just going to try several things since I've got three plants that cost me next to nothing.

Depending on how big they are, you could probabbly keep them at the 55 deg temps, give them some supplemental light from a grow light, easy on the water and they'll probably be ok next spring. But hey...I'm in Florida, so I just leave mine in the ground all year...Z
