Cedrus libani var. libani, commonly known as Cedar of Lebanon, is a majestic evergreen conifer native to the mountainous Eastern Mediterranean region and holds profound historical and cultural significance. This variety has relatively flexible dormancy requirements and can germinate successfully with appropriate cold stratification, though seeds naturally show some variability in germination response. Seedlings are particularly prone to damping-off disease, requiring careful moisture management and good air circulation.
Before sowing
Cold stratification is recommended and effective. Place moist seeds in wet medium (sand, peat, or vermiculite) in closed container in refrigerator at 1-5°C for 30-60 days. Monitor for germination during stratification; transfer sprouted seeds to pots immediately. Seeds can germinate in cold, so inspect regularly.

What to expect
Tips
Seedlings are very susceptible to damping-off—maintain good ventilation and avoid overwatering. Seeds may germinate during cold stratification; transfer any sprouted seeds immediately to individual pots. Surface sow and tamp seeds securely into soil. Once stratified, bring seeds to warm room temperature (20-22°C) for germination. Keep seedlings in protected location with indirect light after emergence. Acclimate seedlings gradually over 2-3 months before final outdoor planting. Transplant into individual pots when first true leaves appear.
