FAQ

Are Cosmos Plants Annuals or Perennials?

Most Cosmos plants are annuals, meaning they complete their life cycle in one growing season. However, some varieties, such as Cosmos bipinnatus and Cosmos sulphureus, are self-seeding and can come back year after year.

How Do You Plant Cosmos Seeds?

Cosmos seeds should be sown directly into the ground after the last frost date in your area. The soil should be well-draining and moist. The seeds should be planted at a depth of ¼ inch and spaced 12-18 inches apart. Water the seeds regularly until they germinate.

How Do You Care for Cosmos Plants?

Cosmos plants require full sun and well-draining soil. They do not require much water once established and are drought-tolerant. Deadheading spent flowers will encourage more blooms. Cosmos plants can also benefit from regular fertilization with a balanced fertilizer.
