Different Stages of Coriander Plant Growth

Early Stage

During the early stage of coriander plant growth, the plant is just beginning to emerge from the soil. At this point, the plant consists of a few small, delicate leaves and a thin stem. The plant is still developing its root system and is very vulnerable to changes in weather conditions. It is important to provide adequate water and protection from extreme temperatures during this stage to ensure healthy growth.


In the mid-stage of coriander plant growth, the plant starts to mature and grow larger. The leaves become more developed and the stem thickens. The plant also starts to produce flowers, which eventually lead to the formation of coriander seeds. In this stage, it is crucial to monitor the plant for any signs of infestation or disease and take necessary measures to prevent any damage to the crop.

Late Stage

During the late stage of coriander plant growth, the flowers transform into seeds. The plant’s energy is focused on seed production, and the leaves may start to wither and turn brown. The coriander seeds ripen and become ready for harvesting. It is important to closely monitor the plant during this stage to ensure that the seeds are harvested at the optimal time for the best flavor and aroma.

Signs of Readiness for Harvesting


When coriander seeds are ready for harvesting, the appearance of the plant undergoes certain changes. The leaves may turn yellow or brown, and the stems begin to dry out. The plant starts to lose its vigor and vitality as it directs all its energy towards seed production. It is essential to carefully observe the plant’s appearance to determine the right time to harvest the coriander seeds.

Color Change

One of the most noticeable signs of readiness for harvesting coriander seeds is a color change. As the seeds mature, they transition from green to a light brown or golden hue. This color change indicates that the seeds have fully developed and are ready to be harvested. It is essential to wait until the seeds reach this stage to ensure optimal flavor and quality.


Another important indicator of the readiness for coriander seed harvesting is the aroma. When the seeds are fully mature, they emit a strong, distinct aroma that is characteristic of coriander. The scent becomes more pronounced as the seeds ripen, and it is a good indication that the seeds are ready to be harvested. It is best to wait until the aroma is potent before harvesting to ensure the best quality seeds.

Taste Testing

Taste testing is a reliable method to determine the readiness of coriander seeds for harvest. Once the seeds have turned brown and emit a strong aroma, you can pluck a few seeds and give them a taste. The taste should be slightly sweet and citrusy, with a mild spicy undertone. If the seeds taste bitter or lack the characteristic coriander flavor, it is an indication that they are not yet fully matured and need more time on the plant.

Timing Considerations

Days to Maturity

The number of days it takes for coriander to produce seeds varies depending on various factors, including the specific variety and growing conditions. On average, coriander plants take approximately 100-120 days from seed germination to seed production. It is important to keep track of the planting date to estimate when the coriander seeds will reach their maturity and be ready for harvest.

Weather Conditions

Weather conditions play a crucial role in the timing of coriander seed harvesting. Coriander plants prefer cool temperatures and thrive in mild climates. Extreme heat or frost can adversely affect the plant’s growth and seed development. It is important to monitor the weather forecast and consider planting coriander during seasons when the temperature is moderate and consistent.

Regional Variation

The ideal time for coriander seed harvesting can vary based on the region in which it is grown. Different climates and growing conditions can impact the development of coriander plants. It is advisable to consult with local gardening experts or experienced farmers in your area to determine the best time for harvesting coriander seeds based on regional variations.

Harvesting Techniques

Hand Harvesting

Hand harvesting is a common and effective technique for harvesting coriander seeds. To hand harvest, you simply pluck the seeds from the plant once they are fully matured and ready. Gently hold the stem of the plant and use your fingers to strip the seeds off into a container. Hand harvesting allows for careful selection and ensures that only the ripest seeds are collected.

Mechanical Harvesting

Mechanical harvesting can be used for large-scale coriander seed production. This technique involves using specialized machinery to efficiently harvest the seeds from the plants. Mechanical harvesters gently shake the plants to release the seeds, which are then collected and separated from the plant material. This method is faster and more efficient for large-scale operations but may not be suitable for small home gardens.

Methods for Cleaning and Drying

Cleaning the Seeds

After harvesting coriander seeds, it is important to clean them to remove any plant debris or impurities. To clean the seeds, place them in a fine-mesh sieve or colander and rinse under running water. Gently stir the seeds and continue rinsing until the water runs clear. This process helps ensure that the seeds are free from any dirt or unwanted particles.

Drying the Seeds

Proper drying is crucial for preserving the quality and longevity of coriander seeds. After cleaning, spread the seeds out in a single layer on a clean, dry surface. Ensure that the seeds are evenly distributed and not clumped together. Place the seeds in a well-ventilated area away from direct sunlight and excessive moisture. Allow the seeds to air dry completely, stirring occasionally to promote even drying. The seeds are ready for storage once they are dry, brittle, and no longer retain any moisture.

Storage Tips for Coriander Seeds

Container Selection

Choosing the right container for storing coriander seeds is essential to maintain their freshness and prevent spoilage. Opt for airtight containers made of glass or food-grade plastic. These materials help to keep moisture and pests out, ensuring that the seeds stay dry and uncontaminated. Mason jars or sealable plastic bags are excellent options for storing coriander seeds.


Select a cool, dark, and dry location for storing coriander seeds. Direct sunlight and heat can degrade the quality of the seeds and reduce their shelf life. Avoid storing the seeds near sources of moisture, such as the kitchen sink or refrigerator. Ideally, a pantry or cupboard in a temperature-controlled area is an ideal location to maintain the seeds’ longevity.

Temperature and Humidity

Coriander seeds should be stored at a consistent temperature between 45-55°F (7-13°C) to maintain their flavor and potency. Fluctuations in temperature can result in moisture condensation within the container, leading to mold or spoilage. Additionally, the storage area should have a relative humidity level of around 50-60% to prevent the seeds from becoming too dry or developing mold.

Protection from Pests

Pests, such as insects and rodents, can be attracted to stored coriander seeds. To protect the seeds from these unwanted visitors, consider placing a small pouch of dried bay leaves or cloves within the storage container. These natural repellents help to deter pests and preserve the seeds’ quality. Regularly inspect the container for any signs of infestation and take immediate action if needed.

Common Mistakes to Avoid

Premature Harvesting

Harvesting coriander seeds before they reach full maturity can result in seeds that are not fully developed and lack the desired flavor and aroma. It is essential to wait until the seeds have turned brown and emit a strong aroma before harvesting. Patience is key to ensure the best quality coriander seeds.

Delaying Harvesting

On the other hand, delaying the harvest of coriander seeds can also lead to undesirable outcomes. Overripe seeds may lose their flavor and become bitter. Additionally, delays in harvesting may result in the seeds being dispersed naturally, leading to self-seeding and potential weed issues. Monitor the coriander plants closely and harvest the seeds promptly when they are ready.
