Check these first
- Inspect the undersides of leaves for clusters of tiny insects.
- Check the new growth tips for sticky residue.
- Look for ants, as they often farm aphids for their honeydew.
Likely causes
Aphid infestation
Most likelyHow to tell: You will see small green or black insects huddled on the undersides of leaves or near the flower buds. They often leave behind a sticky residue called honeydew.
What to do: Spray the plant with a strong stream of water from your hose to knock them off. If they persist, apply insecticidal soap or neem oil once a week until they are gone.
Excessive nitrogen fertilizer
PossibleHow to tell: The plant has very lush, soft growth that seems to attract more bugs than usual. Aphids thrive on this tender, nitrogen rich tissue.
What to do: Stop fertilizing for the rest of the season. Switch to a balanced, slow release fertilizer next year to encourage sturdier growth.

When to worry
A few aphids are normal, but you should act if you see them covering large sections of the plant or if the leaves start to curl.
Stopping it coming back
Encourage beneficial insects like ladybugs to visit your garden by planting flowers nearby. Keep your chicory healthy with proper spacing to improve airflow.
