Propagation of Diospyros Rubicunda Gürke
Diospyros rubicunda Gürke, also known as the Red Star Apple or Mabolo, can be propagated by three methods - seed propagation, grafting, and air layering.
Seed Propagation
The easiest and most common method of propagation for Diospyros rubicunda is through seeds. Sow seeds in a mixture of peat moss and perlite or sand in a 1:1 ratio. Cover the seeds with a thin layer of soil and keep the soil moist. The seeds will sprout in about 4 to 6 weeks. Transplant the seedlings into individual pots once they have two true leaves.
Grafting
Diospyros rubicunda can also be propagated through grafting, which is the process of joining two plants together to create a new plant. The scion, which is the part of the plant that will become the new plant, is taken from a desirable cultivar and attached to a rootstock. The rootstock provides the new plant with a strong and vigorous root system. Grafting should be done in late winter or early spring.
Air Layering
Air layering is a propagation method that is best done during the growing season. Select a healthy and mature branch on the Diospyros rubicunda plant and make a cut in the bark about 10 to 15 cm from the tip of the branch. Take off a small section of bark to expose the inner bark. Apply rooting hormone powder on the exposed area and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with a string or rubber band. Roots will develop within a few weeks. Once the roots have grown to about 5cm in length, cut the branch off below the moss, and plant it in a pot with soil.
