Plant Care:

Coreopsis should be planted in a well-drained, sunny location. For heavier rebloom in September, shear the old flower heads off in August. Divide them in spring or autumn every two to three years, or as needed. This species self-sows. To avoid reseeding, cut the remaining flower heads off at the end of the season. In dry sandy soils, this plant will spread quickly.

List of pests, diseases, and tolerances: 

This plant has no serious pests or diseases. If grown in moist, poorly drained soils, the plant may get crown rot, powdery mildew, or fungal spots. If the soil is too rich or moist, the clumps may sprawl open. Coreopsis is deer resistant.  It tolerates drought, heat, and humidity
