Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and feel soft or mushy to the touch. The soil stays wet for days.
What to do: Let the top 2 inches of soil dry out before watering again. Ensure your pot has drainage holes so extra water can escape.
Nutrient deficiency
PossibleHow to tell: Older leaves turn yellow while the veins remain green. This happens when the plant is hungry.
What to do: Apply a balanced, high potassium fertilizer every 2 weeks during the growing season. Follow the package instructions for the correct amount.
When to worry
It is normal for a few old leaves at the bottom to yellow and drop occasionally. Be concerned if the yellowing spreads rapidly across the whole plant.
Stopping it coming back
Maintain a consistent watering schedule and feed your plant regularly during the spring and summer.

Questions people ask
