Instructions

    • 1

      Prepare the planting site in the spring, after the last frost. Remove the weeds and turn a 3-inch layer of organic compost into the site. The site should get partial sun (four to six hours daily) and have a neutral pH.

    • 2

      Insert the seeds into the soil until they are totally covered. Space the seeds 16 inches apart or farther. Water until the soil settles.

    • 3

      Continue watering frequently enough to keep the soil moist during the growing season. Reduce watering in the winter. Cover the root zone with a 3-inch layer of compost or mulch in the fall to keep the roots warm.

      Cut off any frost-damaged or dead foliage in the spring. Deadhead the flowers during the growing season by pulling off the blooms as they fade.
