Start seeds indoors 6 to 8 weeks before the last frost date. Sow seeds on the soil surface or barely cover them, as they benefit from light exposure for germination. Maintain soil temperature between 60 and 75 degrees Fahrenheit. Keep soil consistently moist but not waterlogged until seedlings emerge.
Transplant seedlings outdoors after the last frost date when soil has warmed and plants have developed 2 to 3 true leaves. Harden off seedlings gradually over 7 to 10 days before moving them to their permanent location. Space plants 15 inches apart in full sun.
Direct sow seeds outdoors after the last frost date. Sow on the soil surface and press gently into place, allowing light to aid germination. Keep soil moist until seedlings are established.
For cut flowers, harvest spikes when approximately two-thirds of the tiny florets along the spike have opened, starting from the base upward. Cut stems early in the morning with a sharp knife, selecting the strongest, tallest spikes. Spikes continue to open in the vase, extending arrangement life.
Deadhead spent flower spikes regularly to encourage continued blooming and maintain the plant's neat appearance along borders. In late fall or early spring, cut back the entire plant to 3 to 4 inches above ground level to rejuvenate growth for the new season.
