Coreopsis plants love the summer sun and heat. They are fairly drought tolerant once they are well-established. They are not too picky about soil, but it does need to drain well. Deadheading helps to encourage continuous blooms up until the first frost. Coreopsis care includes leaving new fall growth at the base of the Coreopsis plant for wintering over and dividing the plant every 2 - 3 years. Directly sow Coreopsis flower seed outdoors in spring into a prepared seed bed. Soil should be loosened and weed free. Press the Coreopsis seeds into the soil but do not cover them. Keep the Coreopsis seed moist until germination. Coreopsis Early Sunrise will bloom the first year after sowing flower seed.
