Why Grow This Coriander

• Fresh leaves and stems add bright flavour to curries, salads, salsas and garnishes.
• Clean roots from plants harvested before flowering are valued in some Asian cuisines.
• White umbels attract beneficial insects before producing ripe coriander spice.
• Its early-flowering description suits gardeners who want seed, while 2–3-week succession sowing keeps younger plants coming for leaves.

Sowing and Care

• Direct sow into fine, fertile, freely drained soil because coriander’s taproot dislikes disturbance.
• Cover 4 mm and keep evenly moist through the full 14–21-day packet window.
• Thin early. Use 30 × 30 cm for a full root or seed plant, or 5–10 cm for a managed leaf row.
• Keep water even and give light afternoon shade where heat is intense; drought and high temperatures hasten bolting.
• Sow a small batch every 2–3 weeks through the cool-to-mild part of your local season.

Harvest and Food Safety

Pick outer stems once plants are about 10–15 cm tall, lift selected non-flowering plants for their roots, or let separate plants flower until the seed turns light brown and dry. Do not eat sowing seed. “Raw seed” describes its physical form and is not proof that a lot is untreated. Follow the physical lot label, use clean irrigation and harvest water, and rinse edible leaves and roots under clean running water before use.
