How to Grow

Sow Cosmos Sensation seeds outdoors after the last frost or start indoors in pots. They prefer full sun and well-drained soil. Thin seedlings to 30cm apart for best growth.

  • Sowing

    Sow Cosmos Sensation seeds indoors from March or directly outside after the last frost. Place one seed per hole on firm, damp soil and cover lightly. Keep in full sun until germination. Thin to 30–40cm apart for strong, upright plants.

  • Growing

    Cosmos grow quickly and love warmth. Pinch out the growing tips when plants reach 20–25cm to encourage bushier growth and more flowers. Water regularly in dry spells but avoid overfeeding, which can cause leafy growth instead of blooms.

  • Plant care

    Deadhead regularly to keep flowers coming into autumn. Tall stems may need staking in windy spots. Cosmos are annuals, but they self-seed lightly if left to drop their petals at the end of the season.
