Neofinetia falcata with Rotted/Dead Roots

[s.kallima]

I noticed that the part of the root close to the base of the plant, when getting old, turn into "wood" (they become very thin like a dry little branch, and they have no longer that green/white fleshy texture). But in many cases, I could still see growing activity at the tip of the root, and even branching of new roots. So I usually only cut a root if the tip is dead.
