Troubleshooting
Chervil problems — and how to fix them
Chervil (Anthriscus cerefolium) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Premature bolting
Heat, drought, and long days send it quickly to flower, ending leaf production. Grow in cool seasons and light shade, keep soil moist, and sow successionally every few weeks.
Transplant shock
The taproot dislikes being moved, so transplants often stall or bolt. Direct-sow into the final position and thin seedlings rather than transplanting.
Aphids
Soft ferny growth attracts aphids that distort the foliage. Rinse them off with water or treat with insecticidal soap, and encourage natural predators.
Damping-off and rot
Crowded seedlings in cold, wet soil rot at the base. Sow thinly, ensure good drainage, and avoid overwatering young plants.
Prevent chervil problems before they start
Most chervil issues are care-mismatch, not bad luck. Dial in the basics:
