I've found from experience that Ensetes can cope fairly well with indoor conditions (both in terms of low light levels and low humidity), unlike some Musa species which seem more attractive to red spider mite. My advice would be to dig it up reasonably soon, while it's still warm, and bring it indoors. If you wait until the cold weather the plant won't be in active growth and is more prone to rotting off.

It should still carry on growing, albeit more slowly, indoors, and the reduced light won't do much harm, as long as it goes back outside when it warms up next spring. I've even overwintered plants quite far from a window and they haven't suffered.

I'm in London, UK, and our Maureliis are beautifully red, due no doubt to not getting an overdose of sun!

Thanks. I'll dig it up within the next few days.

I purchased and planted an Ensete beginning of the summer and it has hardly grown. Its exact species was not identified on the lable. I planted it in full sun. Are Ensete's shade plants and maybe the reason for its stunted growth? Also, can it be cut down and mulched over for the winter like other Banana plants ?

Well I dug mine up and brought it inside. It's actually still growing and starting to look better, the darker color is coming back.

I think these would do fine in full shade outside, at least in the deep south.
