How to tell it is ready

Plants are ready to harvest once they are about 4 to 6 inches tall and have several sets of full, fern-like leaves, usually 6 to 8 weeks after sowing. The leaves should be bright green, soft, and lacy. Once you see flower stalks beginning to form, the plant is bolting and the leaves will turn milder and slightly bitter, so harvest heavily at that stage.

How to harvest

Snip the outer stems near the base with scissors or pinch them off, leaving the central growing point and inner leaves in place so the plant keeps producing. Take a few outer stems from each plant rather than shearing the whole clump, and avoid tearing, which bruises the tender foliage.

Timing

Harvest during the cool spring and fall seasons, picking in the cool of the early morning when the leaves are crisp and full of moisture and before the day warms. Plan on multiple passes over the season, returning every week or two, and combine harvesting with succession sowings every few weeks for a continuous supply. Days to maturity for leaf harvest typically ranges from about 40 to 60 days.

After the harvest

Handle the cut sprigs gently and get them out of the sun quickly, since they wilt fast. Rinse in cool water only if needed and pat or spin dry, then refrigerate right away in high humidity. For the best flavor, use chervil the same day you pick it, or within a couple of days.

Tips

Harvest frequently to encourage tender new growth and to hold off bolting, and cut extra when hot weather threatens, since heat quickly ends the season. Because chervil resents heat, shade and consistent moisture help extend the picking window.
