- Inspect the soil for a sour or musty smell.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow starting from the base of the plant. The soil feels soggy or swampy to the touch.
What to do: Stop watering immediately and let the top inch of soil dry out completely. Ensure the pot has drainage holes so excess water can escape. In the future, only water every 5 to 10 days when the top inch feels dry.
Nutrient deficiency
PossibleHow to tell: The older leaves turn 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 once a month during the growing season. If the plant is very root bound, consider repotting it into fresh soil. This provides the necessary nutrients for healthy green growth.

When to worry
A few yellow leaves at the very base are normal as the plant ages. Worry if the yellowing spreads rapidly to the younger leaves or if the stems feel mushy.
Stopping it coming back
Stick to a consistent watering schedule and never let the plant sit in a saucer of water. Use a potting mix that allows for good drainage.
