I need to cut back my giant Cyperus papyrus. The center is bare because I always cut out the dead stocks. The rhizomes are growing outward from the center. Some are now growing into the patio.

I need to cut these back and would like to replant them. Is all the rhizome above ground? If not how deep do I dig to get enough root to transplant?

When I replant how deep should I plant it since it looks like it's growing on the surface? If I don't plant it deep what's to keep it from falling over? :oops:
