I have an ice cream banana that I would like to try to get it to fruit next yr. I planted the original at least 15 yrs ago and it has been the hardiest that I have ever had. I did have it fruit one yr apparently after what it thought was a mild winter. This winter will not be mild from what I'm reading. Do I cut it at the top of the pseudostem, wrap with blankets, and then cover with plastic to keep the water out? This will all be new to me, hope it is worth a try!
