Germination: In spring or summer, sow outdoors up to 2 months before frost and barely cover the seed. For best results, sow indoors, leave the seeds uncovered and maintain 68-70° F within the medium. Germination takes 10-15 days; blooms arrive 4 months from sowing.
Growth: In spring or summer, space 12 inches apart in part shade in normal garden soil. Pinch early to encourage plants to become more bushy. Keep evenly moist and feed moderately. Mums transplant easily and benefit from the use of a slow-release fertilizer. Mulch for winter. Indoors, grow in cool green house in full sun with soil kept moist.
