Re: When protecting musa-stems for winter....
There are some great ideas here! What I am generally interested in is the insulation properties of pine-bark. I guess Bigdog is right, only one way to find out and try it!
In England, at Kew gardens they use chimney-brick elements (You know, the pourous ones cemented from volcanic rocks?) And stack them on top of the pseudostem. In the cavity they fill up with isulation material. Over the root system they place boards of styrofoam and cover with soil.
