- Place in a heated propagator at a constant temperature of 21-25c.
- Make sure the propagator is placed somewhere bright as light aids germination.
- The seeds will germinate in 8-12 days.
- Once the seedlings are around 5cm, transplant into individual pots.
- Pinch out the seedlings when they have 3 sets of true leaves.
- Gradually acclimatise the plants to cooler conditions.
