🌾 Sow directly in the garden — Chrysanthemum is not usually started indoors.
Since chrysanthemums are perennials often started from division or purchased plants rather than direct seed in many regions, wait until all danger of frost has passed before moving any young starts outdoors.
Soil, care & harvest
Prepare well-draining soil with a pH between 6.0 and 6.5, as chrysanthemums prefer slightly acidic conditions. Start seeds indoors 8 to 12 weeks before the last frost date since they are cool-season perennials that establish best early in the season. Sow seeds about 1/4 inch deep and expect germination within 7 to 14 days under warm, consistent moisture.
Space plants 18 to 24 inches apart to ensure good air circulation and prevent disease. While they do not require trellising unless grown as tall varieties, provide moderate water consistently but avoid wetting the foliage. Apply a light layer of mulch around the base to retain moisture and feed them with balanced fertilizer during the growing season.
Watch for aphids, spider mites, powdery mildew, and rust; prevent these by ensuring proper spacing and avoiding overhead watering. Harvest flowers when buds open fully, typically occurring 60 to 90 days after sowing depending on the variety. Cut stems cleanly just above a leaf node if you wish to encourage further blooming.
