May–June, depending on type and cultivarSow directly for the root crop. Force suitable chicory roots separately in darkness only later.
- Germination and temperature
- Wait for workable, warmed soil; follow the cultivar’s minimum sowing temperature.
- After emergence
- Keep the seed row evenly moist during emergence and identifiable with a label.
- Pricking out and potting on
- Do not prick out. Thin in place; transplanting can damage the taproot.
- Hardening off and planting out
- Stays where sown; hardening off and planting out are unnecessary for direct sowing.
Sow directly for root production. Forcing chicory in darkness later is a separate stage; seedlings are raised in light.
