Cedrus libani, commonly known as the Cedar of Lebanon, is a large evergreen conifer native to the mountains of the Eastern Mediterranean basin, with profound historical and cultural significance spanning millennia. The species exhibits variable dormancy patterns; cold stratification for 30-60 days at 3-5°C significantly improves germination uniformity and success rates. Germination is moderately challenging due to the need for proper stratification timing, consistent moisture control, and protection from damping-off diseases.
Before sowing
Soak seeds at room temperature for 24 hours, then cold stratify for 30-60 days at 3-5°C. Scarification is not required.

What to expect
Tips
Soak seeds for 24 hours in room temperature water before stratification. Cold stratify for 30-60 days at 3-5°C; germination typically occurs 2-8 weeks after warming to room temperature. Sow at shallow depth (1/4 inch or 0.5cm) in well-draining potting soil. Keep soil consistently moist but not waterlogged to prevent damping-off fungal diseases, which are particularly dangerous for seedlings. Maintain room temperature (around 20°C) and indirect light after sowing. Germination can be erratic; sow thinly and remove seedlings as they emerge to avoid disturbance.
