  • Do not exclude from light, and save watering when young.
  • Depending on the temperature, germination can take between 10-21 days.
  • In cooler conditions, and when the seedlings are large enough to handle, transfer in bunches to trays before gradually acclimatising to outdoor conditions for 10-days before planting once all risk of frost has passed.
  • In a sunny spot, in light and moist soil, plant 10cm (4in) apart.
