Growing Eucalyptus from Seed: Cold Stratification and Seedling Care

Eucalyptus Seed Germination Protocol

Step-by-step method for starting eucalyptus from seed pods.

Seed Preparation

1. Collect seeds from mature capsules (woody pods)
2. Place seeds in plastic bag with damp paper towel
3. Refrigerate 4–6 weeks (cold stratification breaks dormancy)

Sowing

• Timing: Spring after stratification
• Medium: 3 inches sterile potting mix in tray
• Sowing: Scatter seeds, cover lightly with sand
• Conditions: Bright light, 65–75°F, consistently moist (not wet)
• Germination: 3–4 weeks; expect low percentage

Transplanting Up

1. Grow in tray to 6 inches tall
2. Gently transplant to quart pots with potting soil
3. Harden off gradually (increase outdoor exposure over 2 weeks)
4. Plant in ground at 12–18 inches tall

Critical Success Factors

• Never let seedlings dry out
• Provide maximum light to prevent etiolation
• Use well-draining mix – eucalyptus hates wet feet
• Protect from frost first winter if in marginal zone

Species Note

Many eucalyptus species exist; confirm your species' hardiness zone before investing time. Some are strictly tropical.
