Step-by-Step Growing Guide
Chervil (Anthriscus cerefolium) is a cool-season annual that bolts quickly in heat — it genuinely thrives in the cool weather of early spring, autumn, and under cover in winter. It prefers well-draining, moderately fertile soil with a pH of 6.0–6.8. Direct sow in situ (chervil dislikes transplanting due to its taproot) from late winter in a sheltered spot, or in late summer for autumn harvest. Scatter seeds on the surface and cover lightly — seeds need some light for germination. Sow in partial shade in warmer months, or full sun in autumn and spring. Germination is irregular; keep evenly moist for best results. Thin to 20 cm apart. Water regularly but moderately. Do not feed with high-nitrogen fertilisers as this produces lush growth with diluted flavour. Succession sow every 3 weeks from February through April and again from August through October. Chervil under cloches or a cold frame provides fresh herbs year-round in temperate climates.
