Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and feel soft or mushy to the touch. The soil stays wet for more than 5 days at a time.
What to do: Allow the top inch of soil to dry out before watering again. Ensure your pot has drainage holes so excess water can escape.
Nutrient Deficiency
PossibleHow to tell: Older leaves turn yellow while the veins remain green. This often happens if the plant has been in the same soil for a long time.
What to do: Apply a balanced liquid fertilizer diluted to half strength. Do this once every 4 to 6 weeks during the active growing season.

When to worry

Stopping it coming back
Maintain a consistent watering schedule and avoid letting the plant sit in standing water.
