How To Grow Purple Coneflowers

Purple coneflowers are easy to grow. The plants thrive best if planted in areas with full sun or part shade. They require well-drained, evenly moist, loam, clay soil, but they tolerate drought once fully established. These plants have poor tolerance to salt (6).

Ideal plant spacing of 18 to 24 inches is advised to allow proper air circulation between plants and keep leaves dry, hence minimize the occurrence of diseases.

Propagation

There are two ways to propagate purple coneflowers – by seed or division.

  • Seeds

Purple coneflower seeds self-sow in fields. Direct sowing in the field is ideal in spring or summer. You can also sow seeds indoors in early spring and transplant the seedlings to the ground in late spring (6).

When sowing seeds indoors, it is essential to keep the air temperature between 60 to 70°F and the seedbed misted until seed germination, typically within 10 to 20 days after sowing (7).

  • Division

Another way to propagate coneflowers is by root cuttings. Purple coneflowers tend to form clumps once established.

Dividing these clumps every 3 to 4 years during spring or fall would avoid overcrowding and enhance flowering.

Care and Maintenance

Once the plants are fully established, it is best to remove dead foliage and stems of purple coneflowers during the fall, winter, or early spring. They could use 12-6-6 slow-release fertilizer (1 lb per 100 square feet) before the emergence of new leaves (7).

Pests and Diseases

Some of the most common plant diseases of purple coneflowers are powdery mildew, stem rot, anthracnose, and aster yellows. The manifestation of these diseases can be minimized by practicing proper plant spacing and sanitation, providing the plant with well-drained soil, and removing of affected plant parts and debris.

Insect pests like aphids, eriophyid mites, and Japanese beetles often cause damages to purple coneflower plants by feeding on the foliage and transmitting diseases.
