I have been growing Ensete for three yrs.I have a way of overwintering unobtrusively and it will fire back up in the Spring.
1. Cut all the leaves off save the last in the Fall before a hard freeze.
2. Place the plant top side down (on like some steps outside or inside; whatever) at like a 30 degree angle overnight to rid the petiole attachments to the pseudostem of any left over water from rains or watering (obviously do this in a place that will not freeze overnight). BE CAREFUL that you do not bruise the pseudostem...
3. Cut off the bottom half of the root system all the way around,
4. Loosen and remove excess soil.
5. Place in as small a pot as you can (literally).
6. Now wait for Spring for it to wake up.
7. When it wakes up fill the pot it is in (should not need much) with 50/50 good potting soil / Perlite mix.
8. Water slightly and as it grows, give it a little more water as it grows, etc; etc, and in no time it will be ready to go back out and give you the visual delight you deserve from it! Maybe even a flower stalk.
