Use and Management
Coreopsis species are generally short-lived and may only last 3 to 4 seasons. Try using these plants as a border or edge. They are also excellent for naturalizing and will reseed themselves. The stalks become long and weak and tend to break in windy or rainy weather. Coreopsis leavenworthii require a sunny position in the landscape. They prefer well-drained soils that are not too rich; rich soils and overwatering cause these plants to topple over. Keep the soil relatively moist and remove dead flowers immediately to prolong blooming. Place these plants 6 to 12 inches apart in the garden. Seed is the most common method of propagation for coreopsis. Division can also be accomplished in the spring or fall.
