Methods of Propagation
There are two primary methods for propagating Blue Atlas cedar:
1. Seed Propagation
Step 1: Seed Collection
- Collect mature cones from healthy Blue Atlas cedar trees in late fall or early winter.
- Allow the cones to dry in a warm, dry place for several weeks until they open and release their seeds.
Step 2: Seed Preparation
- Remove the wings from the seeds to improve germination.
- Soak the seeds in warm water for 24 hours before planting.
Step 3: Planting
- Fill a seed tray with a well-draining seed starting mix.
- Sow the seeds 1/4 inch deep and cover them lightly with soil.
- Keep the soil moist but not soggy.
Step 4: Germination
- Place the seed tray in a warm, sunny location.
- Germination typically occurs within 2-4 weeks.
2. Grafting
Step 1: Rootstock Preparation
- Choose a healthy Blue Atlas cedar seedling or rootstock of a similar species.
- Trim the rootstock to a height of 4-6 inches.
Step 2: Scion Selection
- Cut a scion (stem cutting) from a mature Blue Atlas cedar tree with desirable traits.
- The scion should be 3-4 inches long and have at least two buds.
Step 3: Grafting
- Use a sharp knife to make a T-shaped incision in the rootstock.
- Insert the scion into the incision, aligning the cambium layers (the green, growing tissue).
- Wrap the graft union with grafting tape or a rubber band.
Step 4: Aftercare
- Keep the graft union moist and protected from drying out.
- Place the grafted plant in a shaded location for several weeks to promote healing.
Growing Requirements
Once your Blue Atlas cedar seedlings or grafts have established, they require specific growing conditions to thrive:
1. Soil
- Prefers well-drained, slightly acidic soil.
- Avoid heavy, clay soils that can suffocate the roots.
2. Sunlight
- Full sun to partial shade.
- Young trees may benefit from some shade protection.
3. Water
- Water regularly, especially during hot, dry weather.
- Avoid overwatering, which can lead to root rot.
4. Fertilization
- Fertilize lightly in spring with a balanced fertilizer.
- Avoid overfertilizing, as it can promote excessive growth and weaken the tree.
Care and Maintenance
1. Pruning
- Prune lightly in late winter or early spring to remove dead or diseased branches.
- Avoid heavy pruning, as it can damage the tree’s natural shape.
2. Mulching
- Apply a layer of mulch around the base of the tree to retain moisture and suppress weeds.
- Use organic materials such as shredded bark or compost.
3. Pest and Disease Control
- Blue Atlas cedar is relatively pest- and disease-resistant.
- Monitor for common pests such as aphids and spider mites.
- Treat infestations promptly with appropriate pesticides.
Harvest and Storage
1. Seed Collection
- Harvest mature cones in late fall or early winter.
- Allow the cones to dry and open naturally before collecting the seeds.
2. Seed Storage
- Store seeds in a cool, dry place in an airtight container.
- Seeds can remain viable for several years with proper storage.
