Setup, Compatibility & Care

  1. Sowing Seeds: Sow seeds indoors from February to April on the surface of a good, free-draining compost and lightly cover with compost or vermiculite. Place the seed tray in a propagator at 20-25°C (68-77°F) or seal inside a clear polythene bag. Germination takes 7-21 days.
  2. Watering: Keep the compost damp but not wet, and do not exclude light.
  3. Transplanting: When seedlings are large enough to handle, transplant into 7.5cm (3") pots and grow in cooler conditions.
  4. Acclimatization: When the risk of frost has passed, gradually acclimatize to outdoor conditions over 7-10 days before planting outdoors.
  5. Planting: Plant dahlias 30cm (12") apart on any fertile, well-drained soil in full sun.
  6. Ongoing Care: Feed and water regularly throughout the growing season. Pinch out growing tips when young to encourage bushier growth. Deadhead faded flowers to encourage more blooms.
