Choosing the Right Variety

Coriander, also known as cilantro, is a versatile herb widely used in various cuisines around the world. Before you start planting coriander seeds, it’s important to choose the right variety. While cilantro and coriander are two terms often used interchangeably, they actually refer to different parts of the plant. Cilantro refers to the fresh leaves, while coriander specifically refers to the dried seeds.

Cilantro vs. Coriander

Cilantro, with its fresh and citrusy flavor, is commonly used in salsa, salads, and as a garnish. On the other hand, coriander seeds have a warm, mild taste and are often used in cooking and baking, especially in curries, soups, and breads. When selecting a variety, consider whether you want to focus on harvesting the leaves or the seeds, as this will affect the types of coriander you choose.

Popular Coriander Varieties

There are many different coriander varieties to choose from, each with its own unique characteristics. Some common varieties include ‘Slow Bolt,’ which is known for its slow-bolting nature and is ideal for warm climates, and ‘Santo,’ which is a fast-growing variety with higher leaf yield. Other popular varieties include ‘Leisure’ and ‘Calypso.’ Consider the climate and growing conditions in your area when selecting a coriander variety.

Considering Climate and Soil Conditions

Coriander is a cool-season herb that thrives in temperatures between 50-85°F (10-29°C). It prefers well-draining soil with a pH level of 6.2-6.8. When choosing a variety, take into account your local climate and soil conditions to ensure successful growth. Coriander can tolerate light shade, but it flourishes in full sun. Keep in mind that warmer climates may require additional care and attention to prevent the plant from bolting early.

Preparing the Soil

Before sowing coriander seeds, it’s important to properly prepare the soil to provide an optimal environment for growth.

Selecting the Planting Area

Choose a well-draining area with full or partial sun exposure for planting coriander. Raised beds or containers are excellent options for those with limited space or poor soil quality. Ensure the location you choose receives at least 4-6 hours of sunlight daily for healthy coriander growth.

Soil Requirements

Coriander prefers loamy soil that is rich in organic matter. It thrives in slightly acidic to neutral soil with a pH level between 6.2-6.8. Conduct a soil test to assess the pH level and make any necessary adjustments by adding lime to raise pH or sulfur to lower it. Ensure the soil is well-draining to prevent waterlogging, which can lead to root rot.

Improving Soil Drainage

To improve soil drainage, incorporate organic matter such as compost or well-rotted manure into the soil. This will help loosen compacted soil and enhance its ability to drain excess water. Additionally, adding perlite or vermiculite can aid in soil aeration and prevent water from becoming stagnant around the roots.

Adding Organic Matter

To provide the coriander plants with essential nutrients, mix organic matter such as compost or aged manure into the soil. This will enrich the soil and promote healthy growth. Organic matter also enhances the soil’s water retention capacity, preventing excessive drying out during hot weather.

Sowing the Seeds

Properly sowing coriander seeds is crucial for successful germination and growth. Consider the following factors when sowing your seeds.


Coriander is a cool-season herb that prefers temperatures around 50-85°F (10-29°C). It’s best to sow the seeds in early spring or fall when the temperature is moderate and not too hot. Avoid sowing in extreme heat, as it can cause the plant to bolt prematurely. Alternatively, you can sow coriander seeds indoors in trays, 3-4 weeks before the last frost date, and transplant them once the seedlings are strong.

Direct Seeding vs. Transplanting

Direct seeding involves sowing the coriander seeds directly into the garden or container where they will grow, while transplanting involves starting the seeds indoors and moving them outdoors once they have developed into seedlings. Direct seeding is preferred by many gardeners due to the ease of planting and the reduced risk of transplant shock. However, starting seeds indoors and transplanting can give you a head start on the growing season.

Preparing Seeds for Sowing

Before sowing coriander seeds, it’s important to prepare them properly. Soak the seeds in water for 24 hours before planting, as this helps speed up germination. After soaking, drain the seeds and allow them to dry for a few hours. This process helps soften the seed coat and improves germination rates.

Selecting the Right Containers

If you decide to grow coriander in containers, select containers that are at least 8-10 inches deep to provide enough space for root growth. Use containers with drainage holes to ensure proper water drainage and prevent waterlogging. This will help prevent root rot and other fungal diseases. Fill the containers with well-draining potting soil or a mix of compost and sterile potting soil for optimal growth.

Planting Technique

Proper planting technique is essential for healthy coriander growth. Pay attention to the following factors when planting your coriander seeds.


When planting coriander seeds, consider their spacing requirements. Leave approximately 6-8 inches between each individual plant and 12-15 inches between rows to allow adequate airflow and prevent crowding. This spacing ensures that the coriander plants have enough room to grow without competing for resources.

Seeding Depth

Coriander seeds should be planted at a depth of 1/4 to 1/2 inch (0.6-1.3 cm) in the soil. Gently press the seeds into the soil, ensuring they are covered to the appropriate depth. If the seeds are planted too shallow, they may dry out quickly, while planting them too deep could hinder germination.


Proper watering is crucial for the successful germination and growth of coriander. After sowing the seeds, water the area gently to moisten the soil. Be mindful not to overwater, as excessively wet soil can lead to rotting or disease. Once the plants are established, provide regular watering, keeping the soil lightly moist, but not overly saturated. Aim to water deeply, allowing the water to penetrate the soil to reach the roots.

Preventing Pests and Diseases

Coriander is relatively resistant to pests and diseases, but it’s still important to take preventative measures. Mulching can help suppress weed growth and retain soil moisture, reducing the risk of disease and pest infestations. Additionally, regularly inspect your coriander plants for signs of pests such as aphids, caterpillars, or fungal diseases. If detected, promptly treat with organic insecticides or fungicides to prevent further damage.

Caring for Coriander Plants

To ensure healthy and productive coriander plants, proper care is essential. Consider the following factors when caring for your coriander plants.

Watering Requirements

Coriander plants generally require about 1 inch of water per week. However, the watering needs may vary depending on factors such as temperature, humidity, and soil moisture levels. It’s important to monitor the soil moisture regularly and water accordingly to avoid over or under watering. Always aim to keep the soil evenly moist, but not waterlogged.


Coriander plants benefit from regular fertilization to ensure optimal growth. Apply a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium (NPK) every 4-6 weeks during the growing season. Alternatively, you can use organic fertilizers such as compost or well-rotted manure to provide essential nutrients to the plants. Avoid over-fertilization, as it can lead to excessive foliage growth at the expense of seed production.


Mulching not only helps to conserve soil moisture but also suppresses weed growth around coriander plants. Apply a layer of organic mulch, such as straw or wood chips, around the base of the plants, leaving a small gap around the stem to prevent moisture buildup and potential rot. Mulching also helps maintain a more even soil temperature, which is beneficial for coriander growth.


Regular weeding is necessary to prevent competition for nutrients and ensure the healthy growth of coriander plants. Remove any weeds that emerge around the coriander plants, being careful not to disturb the shallow roots. Hand weeding is often the best method, as it allows for precision and avoids unnecessary damage to the coriander plants.

Harvesting Coriander

When to harvest coriander depends on whether you are looking to harvest leaves or seeds. Consider the following factors when determining the ideal time to harvest your coriander.

Determining Harvest Time

For cilantro leaves, harvest when the plants reach a height of about 6-8 inches (15-20 cm) and have developed a good number of leaves. Harvesting earlier will result in smaller leaves, while waiting too long may cause the leaves to become bitter. For coriander seeds, wait until the plants have flowered and the seeds have turned brown and started to dry on the plant.

Harvesting Leaves

To harvest cilantro leaves, use a pair of clean and sharp scissors or shears to cut the outer leaves from the plant. Avoid cutting off all the leaves at once, as this can stunt the growth of the plant. Instead, selectively remove the outermost leaves, allowing the inner leaves to continue growing. Harvesting regularly will promote continuous leaf production.

Harvesting Seeds

To harvest coriander seeds, wait for the flowers to turn brown and start to dry on the plants. Cut off the entire flower stems and place them in a paper bag to catch any seeds that may fall during drying. Hang the bag in a cool, dry place and allow the seeds to dry completely. Once dry, gently rub the flower stems to separate the seeds from the plant. Store the harvested seeds in an airtight container for future use.

Using Fresh Coriander

Fresh coriander, also known as cilantro, is a versatile herb that adds a burst of freshness to various dishes. Consider the following ways to use fresh coriander in your culinary adventures.

Culinary Uses

Fresh coriander leaves are commonly used in a variety of cuisines, including Mexican, Indian, Middle Eastern, and Southeast Asian. They provide a vibrant, citrusy flavor and are often used as a garnish in salads, salsas, guacamoles, curries, soups, and rice dishes. Add them to your dishes just before serving to preserve their fresh taste and aroma.

Storage and Preservation

To extend the shelf life of fresh coriander, store it properly. Remove any damaged or yellowed leaves and place the coriander bunch in a glass of water, similar to how you would arrange flowers. Cover the leaves loosely with a plastic bag and store in the refrigerator. Alternatively, you can store fresh coriander in airtight containers or freezer bags in the freezer for longer-term storage.

Drying and Storing Coriander Seeds

Coriander seeds have a warm and aromatic flavor that adds depth to a wide range of dishes. Properly drying and storing coriander seeds ensures their freshness and flavor retention.

Harvesting Seeds for Drying

To harvest coriander seeds for drying, wait until the plants have flowered and the flower stems have turned brown and started to dry. Cut off the entire flower stems and place them in a paper bag to catch any seeds that may fall during drying. Hang the bag in a cool, dry place and allow the seeds to dry completely.

Drying Techniques

To dry coriander seeds after harvesting, hang the flower stems upside down in a well-ventilated room. Alternatively, you can spread the flower stems on a clean, dry surface, such as a tray or a screen, and let them air dry naturally. Aim for a dry and warm environment to facilitate the drying process. Once the seeds are completely dry, gently remove them from the stems.

Proper Storage Containers

To maintain the freshness and flavor of dried coriander seeds, store them in airtight containers. Glass jars with tight-fitting lids are ideal for storing dried coriander seeds. Ensure the containers are clean, dry, and stored in a cool, dark place away from sunlight, heat, and humidity. Properly stored coriander seeds can last for up to a year without losing their flavor and aroma.
