How To Grow Cosmos Flowers From Seed. Planting cosmos seeds is super easy. The best time to do so is after the last frost and once the soil is roughly 65 degrees Fahrenheit.

Plant cosmos in an area with well-draining soil that receives full sun. Scatter seeds over the soil. Lightly rake the seeds into the soil so they are about 1/16 to 1/8 inch deep.
