Likely causes
Overwatering
Most likelyHow to tell: The lower leaves turn yellow and feel soft or mushy to the touch. The soil stays damp for more than 14 days.
What to do: Allow the soil to dry out completely until the top inch is dry before watering again. Ensure your pot has drainage holes so excess water can escape.
Nutrient Deficiency
PossibleHow to tell: This is less common for this plant, but it usually happens when the soil is depleted of minerals. You will see general yellowing across older leaves while veins remain green.
What to do: Apply a balanced, slow release fertilizer once in early spring. Follow the package instructions carefully to avoid burning the roots.

When to worry
Worry if the yellowing spreads rapidly across the whole plant or if the stems start to blacken. It is normal for a few older leaves at the base to yellow and drop as the plant grows.
Stopping it coming back
Stick to a strict watering schedule of every 7 to 14 days based on soil dryness. Always check the soil before adding more water.

Questions people ask
- Should I remove yellow leaves?
- Yes, you can snip off yellow leaves to keep the plant looking tidy. This also helps you monitor if the yellowing is continuing to spread.
- Is yellowing always a bad sign?
- Not always, as older leaves naturally die off. If it is just one or two leaves, your plant is likely fine.
