  4. Transplanting: Transplant seedlings when large enough to handle into trays or 7.5cm (3 inch) pots.
  5. Growing On: Grow on in cooler conditions for 10 to 15 days before planting out after all risk of frost, 30cm (12 inches) apart.
  6. Position: Full Sun
  7. Watering: Water regularly, especially during dry periods.
