Seed Propagation
Seeds are the most common method of propagation for Phragmanthera polycrypta (Didr.) Balle subsp. raynaliana Balle. The seeds must be kept moist for successful germination, and sowing the seeds in a well-drained soil mixture is recommended. The seeds should be covered with a thin layer of soil, and the container should be kept in a warm and humid environment until germination occurs. After germination, the young seedlings can be transplanted to individual pots.
Cuttings Propagation
Cuttings propagation is a quick way to propagate Phragmanthera polycrypta (Didr.) Balle subsp. raynaliana Balle. Softwood cuttings with a length of approximately 10cm and a few leaves can be taken during the growing season. The lower leaves should be removed, and the cuttings should be dipped into a rooting hormone to promote root formation. The cuttings are then inserted into a well-draining soil mixture, and the container is kept in a warm and humid environment until root formation occurs.
Air Layering Propagation
Air layering is another method of propagating Phragmanthera polycrypta (Didr.) Balle subsp. raynaliana Balle.
