Ponytail Palm root rot

Root rot is more likely when decline comes with wet soil, sour smell, mushy roots, soft stems, or a sealed pot. It is worth checking carefully before repotting.

For ponytail palm, adjust the diagnosis around this plant profile: Ponytail palms store water in their swollen base. Brown tips are common, but yellowing or soft bases are stronger warnings about wet soil.

How to confirm it

Smell the soil and look for sour or swampy odor.

Slide the root ball out only if decline is severe or the pot has no drainage.

Check for brown, mushy roots versus firm pale roots.

Feel whether the base is firm before watering.

Treat a few dry tips as lower priority than yellowing with wet soil.
