Select a planting site in full sun or part shade with well-drained, slightly acidic soil.
Sow seeds in the fall before the first frost while the ground is still workable. The seeds require a period of cold, moist conditions to germinate. Plant at a depth of one-half inch and space seeds about 12 inches apart. Irrigate after planting.
Keep emerging seedlings moist and provide 1 inch of water weekly during the following summers. Green-headed coneflowers don't tolerate drought well.
Divide every three to four years for optimal growth.
