Eucalyptus dalrympleana, commonly known as mountain gum, is a hardy, fast-growing evergreen tree native to southeastern Australia with distinctive creamy-white bark and aromatic foliage. This species requires cold stratification to break dormancy; seeds germinate readily after a 6-8 week cold period at 4°C, followed by warm conditions of 18-25°C. Seedlings establish quickly in well-draining soil and benefit from bright light immediately after germination.
Before sowing
Cold stratification at 4°C for 6-8 weeks improves germination. Seeds remain viable for several years when stored dry and cool (3-5°C). Collect seed capsules in autumn and dry in warm location to release seeds before stratification.
Sowing
What to expect
Tips
Sow seeds on moist substrate surface and lightly cover with fine sand or vermiculite to reduce damping-off risk. Keep substrate moist but not waterlogged throughout germination. Provide bright light immediately after germination to prevent weak, leggy growth. Transplant seedlings to individual pots once true leaves appear. Harden off seedlings gradually before transplanting outdoors in cloudy, cool days. Provide shade cloth protection (minimum 2 weeks) for young plants. Seeds are extremely small; handle carefully during sowing.
