I leave it as it is. It's airy and dries fast.
It will last forever.

The first time I saw this I tried to remove as much as possible damaging the roots and causing a severe setback for the plant.

It made it extremly difficult to mount. Also, i can't really use things that dry too fast; my enviroment forbids it. Anything less retentive than sphagnum moss requires daily watering.
