Planting & Care

Sow cosmos seeds directly outdoors after the last frost date, or start them indoors 4-6 weeks before transplanting. Press seeds lightly into the soil; they need light to germinate, so do not cover them deeply. Keep the soil evenly moist until seedlings emerge, which usually takes 7-21 days at 70-75°F. Once seedlings are a few inches tall, thin them to the recommended spacing to encourage healthy growth.

Cosmos thrive in full sun and well-drained soil. Water regularly during dry spells, but avoid overwatering, as too much moisture can lead to root rot. Tall varieties may benefit from staking in windy areas. Deadhead spent flowers to prolong blooming and prevent self-seeding if desired. Cosmos generally require little fertilizer; too much nitrogen can reduce flower production.
