1 packet (50 cosmos seeds) (TKA53947)

  • Sow seed on in a good free draining, damp seed compost, 3mm (1/8in) deep, and cover with a fine sprinkling of vermiculite.
  • Place in a propagator or seal container inside a polythene bag and place at 18-25°C (64-77F) until after germination which takes 7-14 days. Do not exclude light as this helps germination.
  • Transplant seedlings when large enough to handle, into trays or 7.5cm (3in) pots.
  • Grow on in cooler conditions for a few weeks before planting out after all risk of frost, 45cm (18in) apart in borders.
  • Pinch out the growing tip, when transplanting, to encourage stems to branch and thus produce more flowers.
