Can yellow leaves turn green again?

No, once a leaf has turned yellow, it will not return to green. It is best to snip it off so the plant can focus energy on healthy growth.

Is yellowing a sign of a disease?

Sometimes, but usually it is cultural. If you see a white dusty coating along with the yellowing, that is powdery mildew, which requires a fungicide.

Feverfew: yellow leaves, causes and fixes

Check these first

Feel the top inch of soil to see if it is soggy.
Check the drainage holes to ensure they are not blocked.
Look for signs of pests like aphids on the undersides of the leaves.

Likely causes

Overwatering
Most likely
How to tell: The lower leaves turn yellow and feel soft or mushy. The soil stays wet for more than a week after watering.
What to do: Let the top inch of soil dry out completely before watering again. Ensure your pot has drainage holes so excess water can escape.
Nutrient Deficiency
Possible
How to tell: The older leaves turn pale yellow while the veins remain green. This often happens if the plant has been in the same pot for a long time.
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

A single yellow leaf at the very base of the plant is usually just an old leaf dying off. If many leaves turn yellow at once, you need to adjust your watering routine.

Stopping it coming back

Stick to a consistent watering schedule and avoid letting the plant sit in standing water.
