Propagation of Neuradopsis austro-africana (Schinz) Bremek. & Oberm.
Neuradopsis austro-africana (Schinz) Bremek. & Oberm. is a rare succulent plant native to southern Africa. It is a slow-growing plant that can be propagated by seeds or cuttings.
Propagation by Seeds
Seeds of Neuradopsis austro-africana (Schinz) Bremek. & Oberm. can be collected from the mature plant's seedpods. The seeds can be sown in sandy soil, shallowly covered, and kept moist. The germination of these seeds can be erratic, and they may take several weeks to sprout.
Propagation by Cuttings
Propagation by cuttings is more common and faster than propagation by seeds. Using sharp and sterile scissors, cut a stem of about 4 to 6 cm in length. Allow the stem to dry for a day before planting. Once the stem has dried, dip the cut end in rooting hormone and plant it in a well-draining mixture of sand and soil. Place the pot in a warm and bright spot and keep it humid. The cutting will root within three to four weeks.
