Overview
Start with the botanical name Coriandrum sativum; common names can refer to more than one species. Match the plant to annual in all zones and local conditions before buying it.
The most reliable results come from loose, well-drained soil, a realistic watering routine and enough room for the mature plant.

How to plant cilantro
- Choose a site with sun in cool weather; afternoon shade in heat and verify drainage after deep irrigation.
- Prepare loose, well-drained soil; avoid burying the crown or compacting the root zone.
- Label the plant with both Cilantro and Coriandrum sativum, then record the planting date.
Growing from seed
- Use fresh, correctly labeled seed when appropriate; the preferred method is direct sow in repeated small batches.
- Keep the medium evenly moist during germination, then change to the mature watering rhythm.
- Thin early for airflow and confirm identity before any harvest.
Growing in containers
Use a container sized for the mature root system, unrestricted drainage and a mix compatible with loose, well-drained soil. Check moisture instead of watering by calendar.
Harvest, dry and store
Harvest
cut leaves young or collect dry coriander seed
Drying
Harvest after surface moisture has dried. Dry small, labeled batches with shade and airflow; fleshy roots or fruits need species-specific food-safety handling.
Storage
Store only fully dry material in a labeled airtight container away from heat and light. Discard material with condensation, off odors or mold.
