Direct Sowing: For direct sowing, plant ‘Sonata Mix’ seeds outdoors after the last frost date when soil temperatures are consistently between 70°F and 85°F. Sow the seeds 1/4 inch deep, spacing them 12–18 inches apart in well-drained soil. Germination typically occurs within 7–14 days, so it’s important to keep the soil consistently moist during this time. Cosmos prefer full sun and can thrive in a variety of soil types, making them a versatile addition to any garden setting.

Early Sowing for Seedlings: To get a head start on the growing season, sow seeds indoors 4–6 weeks before the last expected frost. Use seed trays filled with quality seed-starting mix, planting the seeds 1/4 inch deep. Maintain a temperature of 65°F to 70°F to encourage germination. Once the seedlings have developed true leaves and the danger of frost has passed, transplant them outdoors, spacing them 12–18 inches apart. Water the transplants thoroughly after planting to help them establish themselves in their new environment.

Harvesting: To determine when to harvest ‘Sonata Mix’ Cosmos, look for blooms that are fully open and vibrant in color. The best time to cut flowers is in the morning after the dew has dried. Use sharp scissors or pruners to snip the stems at an angle for better water absorption. These flowers can be enjoyed fresh in arrangements or dried for long-lasting beauty. For drying, hang the flowers upside down in a cool, dark place until they are completely dried, preserving their bright colors and delicate charm.
