Sow the seeds at a depth of 1/4 inch and keep the soil moist but not soggy. Cover the pot with plastic wrap or a clear lid to maintain humidity and place it in a warm area with bright, indirect light.
Germination of Myrsine fosbergii seeds usually takes 2-4 months, and once the seedlings have grown their second set of leaves, they can be transplanted to individual pots.
Cuttings propagation
Propagation of Myrsine fosbergii can also be done using cuttings. Cuttings should be taken in spring or early summer during the plant's active growth phase. Select a healthy stem that is about 4-6 inches long and remove the leaves from the bottom half of the stem.
Prepare a potting mix that consists of peat moss, perlite, and vermiculite, and moisten it well. Dip the cut ends of the stems in rooting hormone powder and insert them in the potting mix. Cover the pot with plastic or a clear lid to maintain humidity and place it in a warm, bright area with indirect light.
Keep the potting mix moist but not soggy and mist the cuttings regularly to maintain humidity. Roots should develop in 2-3 weeks, and once they have, the cuttings can be transplanted to individual pots.
Propagation of Myrsine fosbergii Hosaka can be done using either seeds or cuttings. With proper care and maintenance, the shrub can grow into a beautiful addition to any tropical garden.
