Coriander, also known as cilantro or Chinese parsley, is a versatile herb that has been used in various cuisines worldwide for thousands of years. Its distinct flavor and strong aroma make it a popular ingredient in many dishes. The leaves of coriander, commonly referred to as cilantro, are used fresh in salads, salsas, and soups, while its seeds are ground into a powder called coriander powder or spice.

Aside from its culinary uses, coriander is also rich in vitamins and minerals, making it a healthy addition to your diet. It contains essential oils with antioxidant properties that help eliminate harmful free radicals from your body, reducing oxidative stress and preventing cellular damage. In this article, you will learn about the history of coriander, how to plant and grow it, recommended varieties, how to harvest it, and interesting facts about this herb.

Key Takeaways

• Coriander is a versatile herb used in various cuisines around the world.
• It offers numerous health benefits due to its rich vitamins and minerals content.
• In addition to its culinary uses, coriander has a fascinating history spanning thousands of years, and you can easily plant and grow it in your garden.

Planting

To ensure successful germination, plant coriander in early spring when the soil temperature is between 55-68°F (13-20°C) and after the last frost date. Choose a well-drained soil type, as coriander does not do well in heavy clay soils with poor drainage. Loamy, well-draining soil is preferred. If planting in containers, make sure they have drainage holes to prevent waterlogging. Use potting soil or garden soil mixed with perlite for optimal drainage.

Coriander prefers full sun but can tolerate partial shade. It needs at least 5-6 hours of direct sunlight daily for optimal growth. If you live in a hot climate, providing some afternoon shade can prevent the plants from bolting too quickly.

Space coriander plants about 6 to 8 inches (15-20 cm) apart to ensure proper airflow. This spacing also helps prevent overcrowding and reduces the risk of disease. When planting in rows, space the rows about 12 inches (30 cm) apart.

Avoid planting coriander in high heat and humidity conditions, as it can cause the herb to bolt quickly, leading to an early end to its growing season. Rotate the planting location each year to prevent soil-borne diseases.

In summary, to plant coriander, choose a well-draining soil type, plant in early spring after the last frost date, provide adequate sunlight, space the plants appropriately, and avoid high heat and humidity conditions.

Growing

To grow coriander, you need to provide consistent moisture to establish the root system and promote growth. Water the seedlings regularly, especially during dry periods. Choose a sunny spot with well-drained soil rich in organic matter for planting your coriander seedlings. Coriander thrives in full sun but can tolerate some shade. Ensure that the soil has good drainage to prevent waterlogging. As your coriander plants mature, they will still require regular watering to ensure healthy growth and prevent bolting. However, avoid overwatering as excessive moisture can lead to fungal diseases. Additionally, to prevent bolting, plant coriander during cool weather or provide shade during warm weather.

Recommended Varieties

When it comes to growing coriander, there are several recommended varieties that you should consider. These varieties are known for their unique characteristics and flavors. Here are some of the top recommendations:

• Slow Bolt: This variety is known for its slow bolting nature, which means you will have a prolonged harvesting window. It is ideal for those who want a continuous supply of fresh cilantro throughout the growing season.

• Santo: This variety is renowned for its strong flavor and robust growth. It is perfect for gardeners looking to spice up their dishes with an extra punch of flavor.

• Leisure: If you’re looking for something unique, Leisure is an excellent choice. Its beautiful foliage adds visual appeal to any garden setting. It also boasts a delicate yet aromatic flavor, making it a favorite among culinary enthusiasts.

• Calypso: This variety is prized for its high yield and dense leaf growth. With Calypso in your garden, you can expect plentiful harvests with minimal effort.

All of these varieties can be grown from seeds and will self-seed if allowed to bolt and go to seed. ‘Confetti’ is another variety that is gaining popularity for its compact size and high yield.

Harvesting

Harvesting coriander is a crucial step in growing this herb. The leaves, also known as cilantro, should be harvested once they have reached the desired size, which usually occurs around 3 to 4 weeks after planting the seeds. To harvest the cilantro leaves, use sharp scissors or pruning shears and start by removing the outer leaves while leaving the inner ones intact to allow for continuous growth. It’s essential to remove only about one-third of the plant’s foliage at each harvesting session to prevent stunting its growth.

After harvesting your cilantro, it’s important to store it correctly to maintain its freshness and flavor for longer. Rinse the harvested leaves gently under cold water and pat them dry using a clean towel or paper towel. Place them in a paper bag or an airtight container lined with damp paper towels before storing them in the refrigerator. Cilantro can last up to two weeks when stored this way.

If you have an abundance of cilantro and want to store it for a more extended period, you can freeze it. To freeze cilantro, wash and dry the leaves, chop them, and place them in an ice cube tray. Fill the tray with water and freeze it. Once frozen, remove the cilantro cubes and store them in an airtight container in the freezer. Frozen cilantro can last up to six months.
