Drastic pruning. Can I just chop off the top fan? How far down the trunk can I cut?
Regular pruning is necessary to keep this fast growing palm in check.
Prune spent flower stalks at the base, do not cut into the fan itself.
Remove damaged or brown leaves near the central fan, but do not cut into the fan itself.
Trim off the outer 2 or 3 leaves on each side of the fan to shape it or keep it from spreading.
Never cut into the central fan leader.
Repeat this pruning to keep the palm healthy and from outgrowing it's space.
If it becomes overgrown, it can be difficult to get it in control.
