How to Grow Cedar of Lebanon Trees from Seed (Germination Guide)
The Cedar of Lebanon (Cedrus libani) is a long-lived evergreen valued for layered horizontal branches, blue-green needles, aromatic wood, and a majestic mature form. It is native to Lebanon, Mount Lebanon, the Taurus Mountains, and Turkey.
Growing Cedar of Lebanon from seed begins with a 24-hour water pre-soak. No stratification is required, although the supplier notes that a brief cold period may help induce germination. After soaking, sow the seeds 1/2 inch deep, tamp the soil, mulch the seed bed, and keep the growing medium evenly moist.
Quick Cedar of Lebanon Germination Guide
Pre-soak: Soak seeds in water for 24 hours
Stratification: None required
Optional treatment: A brief cold period may help induce germination
Planting depth: Sow 1/2 inch deep
After planting: Tamp the soil and mulch the seed bed
Moisture: Keep evenly moist, but not waterlogged
Step 1: Soak Cedar of Lebanon Seeds for 24 Hours
Soak Cedar of Lebanon seeds in room-temperature water for 24 hours.
After soaking, the seeds can be planted directly.
Step 2: Stratification Is Not Required
Cedar of Lebanon seeds do not require cold or warm stratification for germination.
The supplier does note that a brief cold period seems to help induce germination, so a short optional chill can be used if desired.
Required stratification: None
Optional treatment: Brief cold period
Purpose: May help induce germination
Step 3: Sow Cedar of Lebanon Seeds 1/2 Inch Deep
After the 24-hour soak, sow the seeds approximately 1/2 inch deep.
- Fill a container or prepared seed bed with a loose, well-draining growing medium.
- Sow each Cedar of Lebanon seed approximately 1/2 inch deep.
- Lightly tamp the soil after planting.
- Water gently and keep the growing medium evenly moist.
- Mulch the seed bed lightly if planting outdoors.
Do Cedar of Lebanon Seeds Need to Be Soaked?
Yes. Soak Cedar of Lebanon seeds in water for 24 hours before sowing.
Is Soaking Cedar of Lebanon Seed the Same as Scarification?
No. Although the supplier lists the soak under scarification, the actual treatment is a 24-hour water pre-soak.
No filing, sanding, nicking, or cutting is specified.
Do Cedar of Lebanon Seeds Need Cold Stratification?
No. Cold stratification is not required.
The original draft treated cold stratification as part of the standard protocol, but the supplier specifically states that the seed does not require stratification.
Can a Brief Cold Period Help Cedar of Lebanon Seeds?
Yes. The supplier notes that a brief cold period seems to induce germination.
This is optional rather than required, so the seeds can also be planted after the 24-hour soak without a cold stage.
How Deep Should Cedar of Lebanon Seeds Be Planted?
Sow Cedar of Lebanon seeds approximately 1/2 inch deep.
The original draft suggested 1/4–1/2 inch, but the supplier protocol specifically calls for 1/2 inch.
What Soil Is Best for Cedar of Lebanon Seeds?
Use a loose, well-draining growing medium.
Keep the seed zone evenly moist during germination while allowing excess water to drain freely.
How Should Cedar of Lebanon Seeds Be Watered?
Keep the growing medium evenly moist during germination and early seedling development.
Avoid continuously saturated soil. Cedar of Lebanon prefers good drainage, especially as the root system develops.
Cedar of Lebanon Seedling Care
Once seedlings emerge:
- Provide bright light
- Keep the soil evenly moist while seedlings are young
- Avoid continuously saturated soil
- Maintain good airflow
- Gradually increase direct sun exposure
- Transplant before roots become severely crowded
Hardening Off Cedar of Lebanon Seedlings
Seedlings started in protected conditions should be gradually acclimated before permanent outdoor planting.
- Begin with short periods outdoors in bright shade.
- Increase outdoor exposure gradually over 7–14 days.
- Introduce morning sun before stronger exposure.
- Protect young trees from drying wind and sudden heat during the transition.
- Keep containers evenly moist.
- Transplant once seedlings are acclimated.
Where Is Cedar of Lebanon Native?
Cedar of Lebanon is native to Lebanon, Mount Lebanon, the Taurus Mountains, and Turkey.
Where Should Cedar of Lebanon Be Planted?
Cedar of Lebanon performs best in sunny, well-drained sites with enough room for its eventual broad, spreading crown.
Good growing conditions include:
- Light: Full sun
- Soil: Deep, well-drained soil
- Moisture: Reliable moisture while young
- Drainage: Avoid standing water and chronically saturated soil
- Airflow: Provide good spacing around the developing tree
- Space: Allow substantial room for a broad mature canopy and extensive roots
How Large Does Cedar of Lebanon Grow?
Cedar of Lebanon can become a very large, long-lived evergreen with a broad, spreading crown.
Choose the permanent planting site with mature scale in mind rather than the size of the seedling.
What Makes Cedar of Lebanon Distinctive?
Mature Cedar of Lebanon trees are known for their layered, horizontal branching and broad architectural crowns.
Blue-green needles and massive branching structure give older trees a distinctive silhouette.
Is Cedar of Lebanon Drought Tolerant?
Established trees can become more tolerant of dry conditions, but young seedlings and newly planted trees still need dependable moisture while their root systems develop.
Will Cedar of Lebanon Grow True from Seed?
Seed-grown Cedar of Lebanon trees are genetically unique.
Individual seedlings may vary in:
- Growth rate
- Needle color
- Branching habit
- Canopy form
- Mature size
Common Cedar of Lebanon Germination Problems
Skipping the Pre-Soak
Soak Cedar of Lebanon seeds in water for the full 24 hours.
Treating Stratification as Mandatory
Cedar of Lebanon seeds do not require stratification.
Confusing an Optional Cold Period with a Requirement
A brief cold period may help induce germination, but it is an optional treatment rather than a required step.
Planting Too Shallow
Sow Cedar of Lebanon seeds approximately 1/2 inch deep.
Keeping the Soil Waterlogged
Maintain reliable moisture while still allowing excess water to drain freely.
Starting Seedlings in Too Little Light
Provide bright light after emergence and gradually acclimate seedlings to stronger sun.
Ignoring Mature Size
Cedar of Lebanon can become enormous and broad with age. Choose a permanent site that can accommodate the mature tree.

Grow Cedar of Lebanon Trees from Seed
Soak 24 hours → No stratification required → Optional brief cold period → Sow 1/2 inch deep → Tamp soil → Mulch lightly → Keep evenly moist
Cedar of Lebanon is easier to start than the original draft made it sound. Give the seed a day in water, skip the refrigerator unless you want to try a brief chill, then plant it 1/2 inch deep. The truly difficult part is finding enough future real estate for the tree.
