Propagation of Voacanga dregei E.Mey.
Voacanga dregei E.Mey. can be propagated by seeds, cuttings or layering methods. Each method has its advantages and disadvantages and is suitable for specific situations.
Propagation by Seeds
Propagation by seeds is the most common method and requires the collection of mature seeds from fully developed fruit. The seeds are then washed, dried, and sown in a mixture of sand and soil in a nursery bed. The bed should be watered regularly, and the seedlings will usually emerge after three to four weeks. The use of a rooting hormone can enhance seed germination, and seedlings should be transplanted to larger containers after they have developed a few leaves.
Propagation by Cuttings
Propagation by cuttings is suitable for mature plants, and it is essential to use only healthy plants. Cuttings of about 20 cm are taken from mature plants, treated with rooting hormone, and planted in a mixture of soil and sand in a nursery bed. The bed should be watered regularly, and the cuttings should develop roots in about six to eight weeks. The rooted cuttings can then be transplanted to larger containers.
Propagation by Layering
Propagation by layering is a technique that involves bending a low-growing stem of the plant, partially burying it in the soil and waiting for the stem to root before separating it from the parent plant. This method is suitable for plants with low-lying branches and can be done during the growing season. The stem should be scraped slightly to encourage rooting and covered with soil. The newly rooted stem can be separated from the parent plant and transplanted to individual containers.
