Likely causes
Overwatering
Most likelyHow to tell: The soil feels soggy and the base of the stems may look mushy.
What to do: Let the top inch of soil dry out before watering again. Ensure your pot has drainage holes so excess water can escape.
Nutrient deficiency
PossibleHow to tell: Older leaves turn pale yellow while the plant growth slows down.
What to do: Apply a balanced liquid fertilizer diluted to half strength. Feed the plant once every 4 to 6 weeks during the growing season.
When to worry
It is normal for the oldest bottom leaves to yellow and die back as the plant grows. Worry if the yellowing spreads rapidly to new growth.
Stopping it coming back
Maintain a consistent watering schedule and avoid letting the plant sit in standing water.
