Propagating Australian Eucalypts from Seed: Tips for Fine Seed Handling

Eucalyptus seed is extremely fine—almost dust-like—mixed with chaff. Here’s how to handle it:

Sowing Method

1. Don’t separate seed from chaff—sow the mixture.
2. Surface-sow on moist, well-draining seed mix (don’t cover; light needed).
3. Cover tray with clear plastic; keep at 68–72°F (20–22°C).
4. Germination in 2–4 weeks for most lowland species.
5. High-altitude species may need cold stratification (4 weeks in fridge).

Transplant seedlings carefully—use tweezers to handle by leaves, not stems.
