Planting & Care
Sow Cosmic Yellow Cosmos seeds directly outdoors after the last frost date, or start them indoors 4–6 weeks before transplanting. Cover seeds lightly with soil, as they need darkness to germinate. Keep the soil evenly moist until seedlings emerge, which typically takes 7–21 days at 70–75°F. Once seedlings are a few inches tall, thin them to the recommended spacing to allow good air circulation.
These plants thrive in full sun and well-drained soil; they tolerate poor soil and dry conditions but may produce fewer flowers in overly rich soil. Water regularly during dry spells, but avoid overwatering. Deadhead spent blooms to prolong flowering, and stake taller plants if they become top-heavy. Cosmic Yellow Cosmos is generally low-maintenance and rarely troubled by pests or diseases.
