Check these first
- Stick your finger 5 centimeters into the soil to check for dampness.
- Lift the pot to see if water is sitting in the saucer.
- Inspect the roots for a foul smell or dark color.
Likely causes
Overwatering
Most likelyHow to tell: The soil stays soggy for a long time and the leaves feel soft or mushy.
What to do: Stop watering immediately and let the top 5 centimeters of soil dry out completely. If the soil stays wet, repot the plant into fresh, well draining soil and trim away any black, mushy roots.
Poor Drainage
PossibleHow to tell: Water pools at the bottom of the pot or the drainage holes are blocked.
What to do: Ensure your pot has large drainage holes at the bottom. Use a chunky potting mix with perlite or orchid bark to improve airflow around the roots.

When to worry
If the yellowing spreads rapidly across multiple leaves, it is a sign of severe rot. It is normal for the oldest, lowest leaf to turn yellow and die off occasionally.
Stopping it coming back
Always wait until the top 5 centimeters of soil are dry before adding more water. Use a pot with holes to allow excess water to escape.
