Learning Download: How to Grow Cosmos

Cosmos can appear in single or double blooms and are easy to care for. The flowers can reach up to 4 feet high but other varieties only reach 1 foot high.

Before Planting: Cosmos grow best in soil that has not been amended, so do not amend the soil prior to planting.

Planting: Scatter the seeds around the planting area and cover lightly with soil, no more than 1/4 inch. Space the seeds 12 to 18 inches apart.

Watering: Water regularly.

Fertilizer: Since Cosmos thrive on poor soil, do not add fertilizer to the plants.

Days to Maturity: Cosmos are good cut flowers that are long lasting and will begin to bloom about 7 weeks after sprouting.

Harvesting: Instead of deadheading, Cosmos can be cut to be displayed indoors and this has the same effect as deadheading would in encouraging more growth on the plant. Harvest when petals on the first flower are just opening, but not yet flattened.

Tips: Cosmos do well when paired with cleome, dahlias and cannas.

Our Seed Promise

"Agriculture and seeds" provide the basis upon which our lives depend. We must protect this foundation as a safe and genetically stable source for future generations. For the benefit of all farmers, gardeners and consumers who want an alternative, we pledge that we do not knowingly buy or sell genetically engineered seeds or plants.

The mechanical transfer of genetic material outside of natural reproductive methods and between genera, families or kingdoms, poses great biological risks as well as economic, political, and cultural threats. We feel that genetically engineered varieties have been insufficiently tested prior to public release. More research and testing is necessary to further assess the potential risks of genetically engineered seeds. Further, we wish to support agricultural progress that leads to healthier soils, to genetically diverse agricultural ecosystems, and ultimately to healthy people and communities.
