Sow seeds 1/4 inch deep into 128-cell plug flats 5-6 weeks before your intended transplanting date. Keep soil temperature between 65-75°F for optimal germination. This cool-weather timing ensures sturdy transplants ready for spring or fall field conditions.
Transplant seedlings out after the danger of frost has passed in spring, or in mid-to-late summer for fall blooming. Space transplants 4 inches apart. Do not pinch plants, as pinching will delay flowering.
Direct seed after danger of frost has passed. Scatter seed at 1/4 inch depth and keep soil consistently moist until seedlings establish.
Cut flowers when they reach full bloom and the lower florets are open. Using a clean sharp knife, cut stems early in the morning or late in the evening when water content is highest. Remove lower foliage from cut stems before arranging.
