Sowing and Growing Guide

Cosmos - Sensation Pinkie

Indoor Sowing

  • Start seeds indoors 4-6 weeks before the last expected frost date.
  • Use seed trays or small pots filled with a light, well-draining seed-starting mix.
  • Sow seeds 0.5 cm deep and lightly cover with soil.
  • Keep the soil moist but not waterlogged.
  • Maintain a temperature of 18-21°C for optimal germination.
  • Seedlings should emerge within 7-14 days.
  • Once seedlings have two sets of true leaves, transplant them into larger pots if needed.
  • Harden off seedlings before planting them outdoors by gradually introducing them to outside conditions over 7-10 days.

Outdoor Sowing

  • Direct sow seeds outdoors after the risk of frost has passed.
  • Choose a sunny location with well-draining soil.
  • Sow seeds 0.5 cm deep and 20-30 cm apart.
  • Gently water the area to keep the soil moist during germination.
  • Seedlings should emerge within 7-14 days.
  • Thin plants if necessary to ensure proper spacing for healthy growth.

Growing

  • Cosmos thrive in full sun and well-draining soil.
  • Water regularly but avoid overwatering, as cosmos prefer slightly dry conditions.
  • No need for heavy fertilization; too much nitrogen can reduce flowering.
  • Deadhead spent flowers regularly to encourage continuous blooming.
  • Taller plants may need staking to prevent them from falling over in strong winds.
  • Cosmos will bloom from summer to autumn and are excellent for attracting pollinators.
  • Cut flowers frequently for bouquets to encourage more blooms.
