Planting Chervil
Chervil is a cool season herb in the Apiaceae family. Getting the timing right is the difference between a strong stand and a disappointing one, so the windows below are given relative to your own last spring frost and first fall frost rather than a generic calendar date. Look up your local frost dates and count back or forward from there.
You can sow Chervil directly into the garden 2–4 weeks before your last frost.

Days to Maturity
Chervil reaches maturity in 40–60 days from sowing.
For a continuous harvest, sow a new batch every 21 days. Use the succession planting scheduler →
Chervil is ready to harvest after about 50 days. Harvest before summer heat or, for fall crops, before a hard freeze, to keep quality high.
Conditions and Care
As a cool-season herb, Chervil does its best growing in the cooler weather of spring and fall and tends to bolt or turn bitter in summer heat. It is half-hardy — it withstands light frost but should be protected from a hard freeze.
Chervil grows well in partial sun and tolerates some afternoon shade, which can help slow bolting in warm weather. Sow seed about 0.125 inches deep — small seed is sown shallow and barely covered, then keep the soil evenly moist until seedlings establish.
Chervil belongs to the Apiaceae family; rotating where you grow members of this family each year helps limit the build-up of soil-borne pests and disease. Because it matures relatively quickly, Chervil rewards succession sowing: small, repeated plantings keep a steady supply coming rather than one short glut.
Companion Plants
Pairing Chervil with the right neighbors can improve growth and deter pests; a few combinations are best avoided.
