How to Grow
Cosmos seeds should be directly sown into prepared seedbeds outdoors after all danger of frost has passed. For a natural setting, the seeds can be scattered onto the prepared soil. Lightly rake the soil over the seeds at a depth of 1/16 inch and keep the area moist. Under proper conditions, these seeds will germinate in 14-21 days. These plants will self-sow and return the next year if some spent blooms are allowed to remain on the plant. However, deadheading will prolong the bloom season for the current year.
