Check these first
- Check if the plant is in direct sunlight.
- Check the soil moisture to ensure it is not too dry.
- Check for signs of pests on the undersides of leaves.
Likely causes
Too much light
Most likelyHow to tell: The leaves look bleached or pale yellow, especially those facing the light source.
What to do: Move the plant to a spot with bright, indirect light. Avoid direct sun, which can scorch the delicate fronds.
Nutrient deficiency
PossibleHow to tell: The leaves turn yellow evenly across the plant over time.
What to do: Apply a balanced, liquid fertilizer diluted to half strength once a month during the growing season.
When to worry
If many leaves turn yellow at once, the plant is in trouble. It is normal for the oldest, bottom leaves to yellow and drop as the plant grows.
Stopping it coming back
Provide consistent, indirect light and a regular feeding schedule during the spring and summer.

Questions people ask
- Is yellowing always bad?
- Not always. If it is just one or two old leaves at the base, it is likely just the natural life cycle of the frond.
- Can I use regular fertilizer?
- Use a balanced, water-soluble fertilizer. Always dilute it to half the recommended strength to avoid burning the roots.
