Light Requirements
Echinacea purpurea var. laevigata prefers full sun, although it can tolerate some shade. In areas with hot summers, some shade in the afternoon may be necessary to prevent sunscald.
Temperature Requirements
This variety of Echinacea thrives in temperate climates with cool winters and warm summers. It can tolerate both heat and cold, but extreme temperatures should be avoided. The best growth occurs when temperatures range between 18-24°C (65-75°F) during the day and 12-18°C (55-65°F) at night.
Soil Requirements
E. purpurea var. laevigata prefers well-draining soils that are rich in organic matter. It can tolerate a wide range of soil pH, from slightly acidic to slightly alkaline. It is important to ensure that the soil does not become waterlogged, as this can lead to root rot.
The plant can grow in sandy, loamy, or clay soils, as long as adequate drainage is provided. Prior to planting, the soil should be worked to a depth of at least 15cm (6 inches) and amended with compost or well-rotted manure to improve soil structure and nutrition.
Cultivation methods
For best results, Echinacea purpurea var. laevigata should be planted in well-draining soil that is rich in organic matter. It prefers full sun exposure but can tolerate some shade. The plant should be watered regularly during the growing season, and its soil should be kept moist but not waterlogged. Echinacea can be propagated through root division and by sowing seeds.
Watering needs
Echinacea purpurea var. laevigata requires regular watering during the growing season. The plant should be watered deeply once a week, or more often during periods of drought. However, its soil should never be allowed to become waterlogged, which can cause root rot. It is best to water the plant in the morning or evening to prevent water evaporation.
Fertilization
Echinacea purpurea var. laevigata is not a heavy feeder and generally does not require fertilization. However, if the soil is poor, or the plant is not growing to its full potential, it can benefit from light fertilization. Organic fertilizers, such as compost or manure, are best suited for Echinacea.
Pruning
Echinacea purpurea var. laevigata does not require regular pruning. However, cutting back the plant in late fall can help improve its overall appearance. Deadheading spent flowers can also promote blooming and prevent seed production. If the plant becomes too thick or overgrown, it can be divided in the spring or fall.
Propagation of Echinacea purpurea (L.) Moench var. laevigata (C.L. Boynt. & Beadle) Cronq.
Echinacea purpurea var. laevigata is commonly propagated by both seeds and root divisions to increase its number in gardens.
Propagation by Seeds
The easiest way to propagate Echinacea purpurea var. laevigata is by using seeds. The seeds should be sown in early spring in a seed tray filled with a good quality seed-starting mixture. The seeds must be kept moist and warm to encourage germination, which typically takes around 14 to 21 days. Once the seedlings have grown to a size that allows for easy handling, they may be transplanted to larger pots or directly into the garden.
Propagation by Root Division
Echinacea purpurea var. laevigata can also be propagated by root division. This method involves separating the roots of an established plant into smaller sections, each with its own growing point. This can be done in early spring or fall when the plant is dormant. The roots should be carefully dug out and washed, and then cut into sections with a sharp, clean pair of garden scissors or a knife. Each section should have at least 1-2 growing points and some roots attached. The sections can then be replanted in the desired location, making sure to water them well.
Both seed propagation and root division are effective ways to propagate Echinacea purpurea var. laevigata, and the resulting plants will typically flower in their second year.
Disease and Pest Management for Echinacea purpurea (L.) Moench var. laevigata (C.L. Boynt. & Beadle) Cronq.
Echinacea purpurea (L.) Moench var. laevigata (C.L. Boynt. & Beadle) Cronq. is a perennial plant that can be affected by various diseases and pests, which can affect its growth and yield. Proper disease and pest management practices can help prevent or control the damage caused by these factors.
Common Diseases
One common disease affecting Echinacea is Powdery Mildew. It is a fungal disease that often appears as a white powdery substance on the leaves and stems. To avoid this, proper air circulation is necessary, and over-watering must be avoided. The use of fungicides can also be effective in controlling the spread of this disease.
Another fungal disease is Septoria Leaf Spot, which appears as small, black spots on the plant's leaves. Proper management includes removing infected plant debris to prevent the spread of this disease. Fungicides are also effective in controlling the spread of this disease.
Common Pests
Echinacea is prone to pests such as aphids, spider mites, and Japanese beetle. Aphids feed on the sap of the leaves and can damage the plant. Proper management includes the use of insecticidal soap or neem oil, which helps control this pest. Spider Mites appear as small dots on the leaves of the plant. These can be controlled with insecticides such as neem oil or a strong jet of water. Lastly, Japanese Beetles can feed on the flowers and leaves of the plant, causing visible damage. Proper management of this pest includes the use of insecticides.
Conclusion
Effective management practices can help prevent or reduce the damage caused by common diseases and pests affecting Echinacea purpurea (L.) Moench var. laevigata (C.L. Boynt. & Beadle) Cronq. Properly maintaining the plants, which includes good plant sanitation and adequate watering, and carefully using insecticides and fungicides when necessary, can make a significant impact in a healthy and thriving Echinacea plant.
