Here are five short germination tips for Eucalyptus grandis (Flooded Gum):
 
Cold Stratification (Optional but Beneficial): Store seeds in the fridge (4°C/39°F) for 2–4 weeks to improve germination rates.
 
Use Well-Draining Soil: A light, sandy, or peat-based seed mix helps prevent waterlogging and promotes root development.
 
Surface Sowing: Sprinkle seeds on top of the soil and press them lightly—do not bury them, as they need light to germinate.
 
Maintain Moisture & Humidity: Keep the soil consistently moist (not soggy) and use a humidity dome or plastic wrap to retain moisture.
 
Warm Temperature & Light: Keep seeds at 20–25°C (68–77°F) with indirect sunlight or a grow light for best results.
