To propagate a Royal Empress tree, there are two methods that are commonly used: propagation from root cuttings and propagation from stem cuttings.
Propagation from root cuttings is typically done in December, when the tree is dormant. For this method, you will need 2-inch pieces of root. To start, dig around the base of the tree and carefully select healthy, young roots. Cut these roots into 2-inch pieces, making sure to include both the woody part and the fibrous roots. It’s important to make clean cuts to avoid damaging the root tissue.
Next, prepare a cutting mix consisting of a well-draining soil mix or a mixture of perlite and peat moss. Place the root cuttings horizontally just below the surface of the cutting mix. Make sure the cuttings are spaced apart to allow for good airflow and prevent them from touching each other.
Keep the cuttings in a warm and bright location, but avoid direct sunlight. Maintain a consistent level of moisture in the cutting mix, ensuring it doesn’t dry out. Over time, the root cuttings will start to develop new shoots and roots. This process can take several weeks to a few months, so be patient and monitor the progress regularly.
Propagation from stem cuttings is another method that can be used to propagate Royal Empress trees. This method involves taking 2- to 3-inch pieces of “half-ripe” wood, which refers to wood that has recently grown and is not fully mature. It is best to take stem cuttings in July or August when the tree is actively growing.
To start, select healthy and vigorous branches from the tree. Using a sharp and clean pruner, make a clean cut just below a node (the point where a leaf emerges from the stem). Remove any leaves from the lower half of the cutting to reduce water loss and encourage root development.
Prepare a well-draining rooting medium such as a mixture of perlite and peat moss or a commercial rooting mix. Moisten the medium slightly to provide a favorable environment for root growth. Dip the cut end of the stem cutting into a rooting hormone powder to promote root development.
Insert the stem cutting into the rooting medium, making sure that at least half of the cutting is buried. You can place multiple cuttings in a container, but make sure they are spaced apart to allow for airflow. Cover the container with a clear plastic bag or use a propagating dome to create a humid environment.
Place the container in a warm location with bright, indirect light. Avoid exposing the cuttings to direct sunlight, as this can cause excessive heat and drying. Mist the cuttings regularly to maintain humidity and prevent them from drying out.
Check the cuttings regularly for signs of root development, such as new growth or resistance when gently tugged. This process can take several weeks to a few months, depending on the conditions and the vigor of the cuttings.
Once the cuttings have developed a strong root system, they can be transplanted into individual pots or directly into the garden. Provide them with well-draining soil, regular watering, and adequate sunlight to ensure their healthy growth.
Remember, successful propagation requires patience, attention to detail, and proper care. Keep in mind that not all cuttings may successfully root, so it’s a good idea to take multiple cuttings to increase your chances of success.
