Ponytail Palm root rot

Yellowing and wilt in wet mix warrant inspecting roots. The swollen base should feel firm; wet-soft tissue there means damage has spread beyond the roots.

Firm base, damaged roots

Remove collapsed roots with clean tools, discard old mix, and use a clean draining pot sized to the surviving roots. Allow fresh fleshy cuts to dry at the surface and replant in succulent mix. Keep bright indirect light during recovery and let the mix dry through between waterings.

If the base is soft, see the soft-base guide. Repotting a fully rotten storage base into dry soil will not restore it.
