- Inspect the base of the plant for mushy stems.
Likely causes
Overwatering
Most likelyHow to tell: The leaves feel soft or mushy and the soil remains damp for days after watering.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. Ensure your pot has drainage holes so excess water can escape.
Poor Drainage
PossibleHow to tell: Water pools on the surface of the soil or the pot feels heavy for a long time.
What to do: Repot your plant into a gritty, well draining cactus or succulent mix. Add perlite or coarse sand to improve airflow around the roots.

When to worry
If the yellowing spreads rapidly across the whole plant, it is a sign of root rot. A single yellow leaf at the base is often just natural aging.
Stopping it coming back
Always allow the soil to dry out slightly between waterings to keep the roots healthy.
