To ensure a continuous supply of fresh coriander throughout the summer, sow seeds every two weeks for a successional harvest.

When planting coriander, sow seeds 1 to 2 inches apart in rows 8 inches apart, covering them with ¼ inch of fine soil. Ample moisture is crucial for seed germination, so be sure to water frequently and provide approximately one inch of water per week. Seeds should typically germinate within 2 to 3 weeks, and regular watering is essential for healthy seedling development.

Growing Conditions and Environment

Sunlight Requirements

Coriander thrives in areas with full sun but can tolerate some shade during the height of summer. Ensure that the plant is placed in a sunny spot or near a south-facing window to provide ample light for optimal growth.

Temperature and Climate

For successful growth, cilantro should be planted in cool weather, either in early spring after the last frost or in the fall once temperatures have consistently cooled down to 50 to 80 degrees Fahrenheit. It’s crucial to monitor the temperature, as cilantro may bolt or go to seed in hotter conditions.

Soil and Drainage

To ensure healthy growth, coriander requires well-drained soil that is rich in organic material. Follow these steps for optimal soil preparation:

  • Test the soil’s pH level: Coriander grows best in slightly acidic soil with a pH between 6.0 and 6.7. A soil test kit can be used to determine the pH level.
  • Plant the seeds 1/4 inch deep in well-draining soil and water thoroughly. Space the seeds about 1 inch apart.
  • Once the plants are about 2 inches tall, thin them to 6 inches apart to give them room to grow.

Keep in mind that coriander has a long tap root, so avoid damaging the roots when transplanting or handling the plant. Proper drainage is crucial, as excess water can lead to root rot or other issues.

Planting and Care

Choosing Coriander Varieties

When selecting coriander varieties, consider factors such as climate, growing season, and intended use. Some popular varieties include:
