Propagation: The primary propagation method for cosmos is through seeds, sown after the last frost or started indoors. Successful growth requires full sun, moderate temperatures, and well-draining soil. Germination occurs in 7-14 days; care includes maintaining moisture, thinning seedlings, and careful transplanting.
