The plant can be pruned to any desired shape, but it is recommended to avoid heavy pruning as it can affect the flowering and fruiting of the plant.
Propagation of Myrica arborea Hutch.
Myrica arborea Hutch., commonly known as the tree wax myrtle, can be propagated by several methods. The plant is often propagated through seeds, cuttings, and air layering.
Propagation by Seeds
Propagation by seeds is the most common method for Myrica arborea. The seeds should be sown in a well-draining soil mix, preferably in a tray or pot. After sowing the seeds, cover them lightly with soil and keep them moist. The seeds should germinate within four weeks. Once germinated, allow the seedlings to grow in their original containers until they have developed four to six leaves, at which point they can be transplanted into larger pots or directly into the ground.
Propagation by Cuttings
Propagation of Myrica arborea by cuttings involves taking a stem cutting of around 6-8 inches in length. The cuttings should be taken from the current season's growth, during the summer months. Remove all the leaves from the bottom half of the cutting and dip it into rooting hormone. Then, insert the cutting into a well-draining soil mix, ensuring that at least two nodes are buried in the soil. Water the cutting and cover it with a plastic bag or a cloche to retain humidity. The cuttings should root within six to eight weeks. Once rooted, transplant the cuttings into individual pots filled with a good-quality potting mix or directly into the ground.
Propagation by Air Layering
Air layering involves inducing roots to grow on a stem while it is still attached to the parent plant. Select a healthy branch of around 1 inch diameter and make a 2-inch-long incision, removing a thin strip of bark. Apply rooting hormone to the exposed wound and wrap it with moist sphagnum moss, followed by plastic wrap or aluminum foil. Ensure that the moss remains moist and check periodically for root growth. Once roots have formed, cut the stem below the rooted area and transplant it to a pot or directly into the ground.
