Tips to Grow Cosmos

  1. Arrange good quality cosmos seeds.
  2. The soil should be moist. They like soil that is not too rich.
  3. Plant seeds lightly about 0.25 inch deep in the soil and about 6 inches of space in consecutive plants.
  4. Cosmos flowers can tolerate warm, dry weather. They are even drought-tolerant.
  5. You can cut the flowers off anytime after blooming, but it’s best to pick some right when the petals have opened.
  6. If you cut the blossoms on good stems when they first open, they’ll last more than a week in water. Simply strip off the lower leaves and put them in a vase.

NOTE: Cosmos is the heart of a summer garden, and it adds a distinct elegance to bouquets in everything from jelly jars to silver urns.
