Setup, Compatibility & Care Instructions

Indoor Sowing (March - May):

  1. Fill a seed tray with moist seed compost.
  2. Sow seeds approximately 5mm deep and lightly cover with compost.
  3. Maintain a warm environment (15-20°C) and keep the compost consistently moist.

Growing On:

  1. Once seedlings are large enough to handle, transplant them into individual pots or trays of potting compost.
  2. Keep them in a light location, but protect them from direct, harsh sunlight.

Hardening Off & Planting Out (Early Summer onwards):

  1. Gradually acclimatize seedlings to outdoor conditions over 2-3 weeks.
  2. Plant outdoors in well-drained soil, spacing plants approximately 25cm apart.

Outdoor Sowing (When soil is warm):

  1. Sow seeds thinly directly into prepared garden beds.
  2. Lightly cover with soil and keep consistently moist until germination.
  3. Thin seedlings to 25cm apart, transplanting any thinnings to other suitable locations.

Aftercare:

  • Watering: Water regularly, especially during warm, dry periods.
  • Feeding: Use a liquid plant food periodically, particularly during the growing season.
  • Deadheading: Regularly remove spent blooms to encourage further flowering and prolong the bloom period.
