Growing directions
Lightly crush the husks before sowing, then press seeds 1/4 in into the soil and keep evenly moist until germination. Thin seedlings to 6 in apart so plants don't compete for moisture, which slows bolting. Avoid transplanting; cilantro's taproot resents disturbance. Begin harvesting outer leaves once plants reach 4–6 in, and harvest seed heads (coriander) when they turn tan and dry on the stem.
Source and local conditions
Typical planning ranges from OpenPlantDB (CC0). Cultivar, climate, season and growing method can change these values. Confirm the seed label and local guidance before planting.
