  • Soil requirements: Cosmos bipinnatus prefers well-drained soil with a pH level between 6.0 and 7.0. The soil should be moderately fertile, as overly rich soil can lead to excessive foliage growth at the expense of flowers.
  • Sunlight needs: These seeds require full sun to thrive. They need at least 6 to 8 hours of direct sunlight each day.
  • Watering requirements: Water the seeds regularly but do not overwater. Cosmos bipinnatus is drought-tolerant once established, so allow the soil to dry out between watering sessions. Water deeply but infrequently.
  • Planting season: The best time to plant Cosmos bipinnatus seeds is in the spring after the last frost has passed. They can also be started indoors 4 to 6 weeks before the last frost date.
  • Depth and spacing: Plant the seeds about 1/4 inch deep and space them approximately 12 to 18 inches apart to allow for adequate air circulation and growth.
  • Germination time: Cosmos bipinnatus seeds typically germinate within 7 to 21 days under optimal conditions.
  • Maturity time: Cosmos bipinnatus plants usually reach maturity and begin to bloom within 70 to 90 days after planting.
  • Harvesting time: The best time to harvest Cosmos flowers is early in the morning when the blooms are fresh and hydrated.
  • Harvesting tips: Use sharp scissors or pruning shears to cut the flowers. For the longest vase life, cut the stems when the flowers are just beginning to open. Store the cut flowers in a cool place and change the water in the vase every couple of days.
