Propagation of Gomphocarpus phillipsiae (N.E.Br.) Goyder
Gomphocarpus phillipsiae (N.E.Br.) Goyder, commonly known as the Phillips' milkweed, is a South African native plant that belongs to the family Apocynaceae. The propagation of this plant can be done through various methods, including:
Seed propagation
Phillips' milkweed can be easily propagated through seeds. The seeds of this plant need to be sown in well-draining soil in a bright, warm place. The seeds should be covered with a thin layer of soil and kept moist until germination. Germination usually takes around two weeks, and the seedlings should be transplanted to their desired location after they have developed two sets of true leaves.
Cuttings propagation
Gomphocarpus phillipsiae can also be propagated through stem cuttings. Select a healthy stem of around 10 - 12 cm in length, and remove all the leaves from the bottom half of the stem. Dip the cut end of the stem in rooting hormone, and plant it in a well-draining soil mixture. Cover the cuttings with a clear plastic bag to maintain humidity and place them in a bright, warm place. The cuttings should start rooting within 4-6 weeks, and they can be transplanted to a new location after they have developed a strong root system.
Division propagation
Gomphocarpus phillipsiae can also be propagated through division. This method is ideal for mature plants. To divide the plant, dig it out of the ground and gently separate the roots into two or more sections. Each section should have a few stems and a healthy root system. Transplant the sections into a well-draining soil mixture in their desired location, and water them in.
