Likely causes
Overwatering
Most likelyHow to tell: The soil feels soggy and the leaves look limp or pale yellow.
What to do: Let the top 1 to 2 inches of soil dry out completely before watering again. Ensure your pot has drainage holes so water does not pool at the bottom.
Nitrogen Deficiency
PossibleHow to tell: Older leaves turn yellow while the plant growth slows down significantly.
What to do: Apply a balanced liquid fertilizer diluted to half strength every 4 weeks. Avoid over fertilizing as this can burn the roots.

When to worry

Stopping it coming back
Maintain consistent soil moisture and feed your parsley with a mild fertilizer during the active growing season.
