- Check the undersides of the leaves for tiny pests.
Likely causes
Overwatering
Most likelyHow to tell: The lower leaves turn yellow and feel mushy to the touch. You might also notice a sour smell coming from the pot.
What to do: Stop watering until the top inch of soil feels dry. Ensure your pot has drainage holes so excess water can escape freely.
Nutrient deficiency
Most likelyHow to tell: The leaves turn a pale yellow while the veins remain green. This happens when the plant has been in the same soil for a long time.
What to do: Apply a balanced liquid fertilizer diluted to half strength every 4 to 6 weeks during the growing season. If the plant is very root bound, consider repotting it into fresh, nutrient rich soil.

When to worry
It is normal for the oldest bottom leaves to yellow and drop as the plant grows. Worry if the yellowing spreads rapidly to the new growth or if the stems feel soft.
Stopping it coming back
Maintain a consistent watering schedule and never let the plant sit in a saucer of standing water.
