- Soil: Well-drained, fertile soil with a neutral pH is ideal.
- Planting: Sow seeds directly in the soil or a pot. Seeds should be planted 1-2 cm deep.
- Watering: Keep the soil moist but avoid overwatering. Regular, moderate watering works best.
- Sunlight: Coriander needs partial to full sunlight. Too much direct sunlight can cause the plant to bolt (flower too early), which affects leaf production.
- Harvesting: Leaves are ready for harvest 3-4 weeks after planting. For seeds, wait until the plant flowers and the seeds start to dry on the plant.
