I need to remove all the old potting media, so I pull out the garden hose and spray the roots. I work the roots with my fingers to separate the roots and loosen the old media.
Here's the plant with most of the media removed.
I looked to divide the plant and found one easy point to separate. I use a sharp knife and cut through the rhizome.
Where I cut, I sprinkle with cinnamon. Most times I will add a pint of bleach to my soak water to kill everything that could harm the plant. Since I'm using worm tea in the soak I decided not to use the bleach. The cinnamon should help to protect the plant.
Now I need to repot/mount the 3 pieces. I think I'll mount the small piece on some cork.
