Once the seedlings are large enough, they can be transplanted to their permanent location.
Cuttings Propagation
Propagation of Alectryon macrococcus Radlk. through cuttings is also possible. Take 15-20 cm cuttings from a mature mother plant, in early spring or summer. Dip the bottom of the cuttings in rooting hormone and place them in a well-draining potting mix. Keep the soil moist and the cuttings in an area with bright, indirect light. It may take several weeks for the cuttings to form roots, so patience is key. Once roots have developed, the new plants can be potted separately or transplanted to their permanent location.
Air-layering Propagation
Air-layering is another propagation method that can be used for Alectryon macrococcus Radlk. This technique involves creating a small cut on a healthy stem, covering the cut with rooting hormone and wrapping the area with sphagnum moss until roots begin to form. Once a sufficient amount of roots have developed, the new plant can be separated and placed into a container of soil.
Overall, Alectryon macrococcus Radlk. can be easily propagated through seed, cuttings, and air-layering methods. Regardless of the method of propagation, it is essential to provide the appropriate growing conditions so that the new plants can grow healthily.
