Overwatering and root or base rot
Wet soil plus yellowing lower leaves and a soft base is the number-one way to lose a Ponytail Palm.
Diagnosis
Overwatering and root or base rot
What's happening
Despite the name, Ponytail Palm is a succulent (Beaucarnea) that stores water in its swollen caudex. It is built for drought, not constant moisture. When the soil stays wet, the roots suffocate and rot, the decay creeps into the bulbous base, and the oldest leaves yellow and droop as the plant fails to feed them.
How to fix it
Stop watering immediately and let the soil dry out completely. Slip the plant out and inspect the roots and base — firm tissue is healthy, while brown, mushy, or foul-smelling tissue is rot. Trim away every soft root with sterilized scissors and repot into fast-draining cactus or succulent mix in a pot with drainage holes. Going forward, water only when the soil is bone dry several inches down, roughly every 2–4 weeks, and never let the pot sit in a saucer of water.
What fixes it
- A gritty cactus & succulent mix — A gritty cactus and succulent mix drains fast so the caudex never sits in moisture.
If that doesn't fix it
This is general guidance based on common symptoms; individual plants vary.
