Planting & Care

Sow Sulphur Yellow Cosmos seeds directly outdoors after the last frost date, as they resent transplanting. Scatter seeds over prepared soil and lightly cover with 1/4 inch of soil, then keep evenly moist until germination, which typically occurs in 7-21 days at 70-75°F. Once seedlings are a few inches tall, thin them to 12-18 inches apart to allow good air circulation.

These cosmos are low-maintenance and thrive in full sun with minimal watering. Avoid over-fertilizing, as rich soil can lead to excessive foliage and fewer blooms. Deadhead spent flowers to encourage continued blooming, or leave some seed heads to self-sow for next year. Taller varieties may benefit from staking in windy areas.
