You can leave them to die off naturally, but I prefer to tidy up the
"trunk"
every so often and remove the older, tattier, more yellowed leaves.


any recommendation on how long I should leave the stump?


I clear mine up to the tatty laves each year - leaving the crown untouched.
I started at around 30 cm 5 years ago and is now around 1m with a crown of
8/10 leaves.

DON'T chop off the top - ever!
