Coriander (Cilantro)

Coriandrum sativum · Herb

A fast herb grown for its fresh leaves and, later, its aromatic seeds. It runs to flower quickly in heat, so short, repeated sowings work best. Treat it as a quick crop rather than a long-lasting plant.

Step by step

1. Lightly crush the round seed husks to help them sprout.
2. Sow directly 1/4–1/2 in deep; coriander dislikes being moved.
3. Keep the soil moist; seedlings appear in 7–14 days.
4. Thin seedlings so each has room to bush out.
5. Start cutting outer leaves once plants are about 6 in tall.
6. Avoid letting the soil dry out; stress pushes the plant to flower.
7. Sow a fresh row every few weeks for a steady supply.
8. Let a few plants flower and dry for seed or to self-sow.
