Germination tips
Sow: Sprinkle seeds on the surface of a well-draining seed mix; lightly press them in.
Do not bury deeply: Seeds need light to germinate.
Temperature: 20–25°C is ideal.
Moisture: Keep the medium consistently moist but never waterlogged.
Germination: Usually 1–4 weeks.
Transplant: Move seedlings carefully once they have several true leaves.
Light: Provide bright light after germination and gradually acclimatize to full sun.
Tip: Eucalyptus seeds are very small, so mixing them with a little fine sand can make even sowing easier.
