Likely causes
Overwatering
Most likelyHow to tell: The lower leaves turn yellow and feel soft or mushy to the touch. The soil remains wet for several days after watering.
What to do: Allow the top 2 inches of soil to dry out completely before watering again. Ensure your pot has drainage holes and never let the plant sit in a saucer of standing water.
Nutrient Deficiency
PossibleHow to tell: The leaves turn a pale yellow while the veins remain green. This often happens if the plant has been in the same pot for more than two years.
What to do: Apply a balanced liquid fertilizer diluted to half strength once every 4 weeks during the growing season. If the plant is root bound, repot it into a slightly larger container with fresh potting mix.

When to worry
Worry if the yellowing spreads rapidly across the entire plant. It is normal for the oldest bottom leaves to yellow and drop as the plant matures.
Stopping it coming back
Maintain a consistent watering schedule and ensure the soil drains well to keep the roots healthy.
