2.2 Growing Requirements

Soil: Echinacea plants prefer well - drained soil. Sandy loam or loamy soil types are ideal as they allow proper root development. The soil should also be rich in organic matter.
Sunlight: Adequate sunlight is crucial for the growth of echinacea. They require at least six hours of direct sunlight per day. Partial shade can be tolerated, but it may affect the overall growth and the concentration of active compounds in the plant.
Water: While echinacea is somewhat drought - tolerant, regular watering is necessary during the growing season, especially in dry periods. Over - watering should be avoided as it can lead to root rot.

3. Cultivation Practices

3.1 Propagation

Echinacea can be propagated through seeds or by dividing mature plants.

Seed Propagation: Seeds should be sown in the spring or fall. Before sowing, it is advisable to stratify the seeds for a period of time to improve germination rates. This can be done by placing the seeds in a moist, cold environment for a few weeks.
Division: Dividing mature plants is another common method. This is typically done in the spring or fall. Care should be taken to ensure that each divided section has a healthy root system.

3.2 Pest and Disease Management

Pests: Common pests that may affect echinacea include aphids, spider mites, and Japanese beetles. Integrated pest management (IPM) techniques are recommended. This may involve the use of natural predators, such as ladybugs for aphid control, or the application of insecticidal soaps in case of severe infestations.
Diseases: Fungal diseases, such as powdery mildew and root rot, can be a problem. To prevent fungal diseases, proper spacing between plants should be maintained to ensure good air circulation. In case of disease outbreaks, fungicides may be used, but organic and environmentally - friendly options should be preferred.

4. Harvesting Echinacea

4.1 Timing of Harvest

The timing of the harvest is crucial for obtaining high - quality echinacea for extract production. For Echinacea purpurea, the best time to harvest is usually when the flower heads are fully developed but before they start to wilt. This is typically in the second or third year of growth.

4.2 Harvesting Methods

Harvesting can be done by hand or using small handheld tools. Hand - harvesting is often preferred as it allows for more selective picking and reduces damage to the plants.
When harvesting, it is important to cut the flower heads cleanly, leaving a short stem attached.

5. Drying and Storage of Echinacea
