Tips & Best Practices
- Direct sow cilantro 2–3 weeks before the last frost — it prefers cool weather.
- Cilantro bolts quickly in heat; succession plant every 2–3 weeks.
- Let some plants go to seed to harvest coriander and encourage self-seeding.
- Slow-bolt varieties like "Calypso" or "Santo" last longer in warm weather.
