What Tools Are Used in Cedar Of Lebanon Propagation?

Sharp pruning shears or a knife

Essential for taking cuttings of cedar of lebanon, these tools should be exceptionally sharp and clean to ensure clean cuts that do not damage the plant tissues. A smooth cut helps in faster healing and reduces the risk of infection, crucial for the successful rooting and growth of cedar of lebanon cuttings.

Rooting hormone powder or gel

This is applied to the cut end of cedar of lebanon cuttings to promote root development and increase the chances of successful rooting. The hormone stimulates root growth at the cut site, essential for the establishment of healthy new cedar of lebanon plants.

Propagating medium

A well-draining, sterile propagating medium such as sand, perlite, or vermiculite is recommended for cedar of lebanon. This medium provides support and the necessary aeration for cuttings of cedar of lebanon, facilitating the development of healthy roots without retaining excessive moisture, which can lead to rot.

Misting bottle

Used to maintain humidity around the cedar of lebanon cuttings, a misting bottle helps to keep the moisture levels optimal. Elevated humidity reduces water loss from the cuttings, essential until the new roots are developed and able to support water uptake on their own. Regular misting can significantly enhance the rooting success rate of cedar of lebanon.

Plastic covers or mini-greenhouse

Placing the propagation trays or pots under plastic covers or inside a mini-greenhouse creates a controlled humidity environment, beneficial for cedar of lebanon cuttings. By maintaining high humidity and stable temperature, these covers help prevent the cuttings from drying out before rooting, thereby enhancing the overall success rate of propagation.

Propagation Type

Moderately Difficult

Select Cutting

Obtain semi-hardwood cuttings from healthy cedar of lebanon trees. Look for branches that are moderately firm and not fully lignified, approximately 6-10 inches in length. Ensure the cuttings are taken from vigorous, disease-free branches.

Prepare Cutting

Strip the lower third of leaves from the cutting to expose the nodes. Make a clean cut just below a node as this area contains high concentrations of growth-inducing hormones which encourage rooting.

Rooting Hormone Application

Dip the basal end of the cutting into a rooting hormone powder or gel. This will facilitate faster and more reliable root development.

Plant the Cutting

Fill a pot with a well-draining rooting medium such as a mix of peat and perlite or coarse sand. Make a hole in the medium and insert the treated cutting, ensuring that the stripped nodes are below the surface. Gently firm the medium around the base to provide support.

Maintain Moisture and Temperature

Place the pot in a greenhouse or under a plastic cover to maintain high humidity and avoid dehydration of the cutting. Keep the pot in indirect sunlight and maintain a temperature around 70°F. Water lightly to keep the medium consistently moist but not waterlogged.

How to Care for Your Newly Propagated Cedar Of Lebanon?

After the cuttings of cedar of lebanon have rooted and begin to show new growth, gradually acclimate them to less humid conditions by removing the plastic cover for increasing periods each day over a week. Once fully acclimated, transplant the young plants to larger pots or directly into the ground if the climate is suitable. Continue to water them regularly and protect from extreme temperatures. An annual mulching will help retain soil moisture and provide nutrients. Monitor for pests and diseases and address any issues promptly to ensure healthy growth.
