Propagation of Gomphocarpus spathulatus
Gomphocarpus spathulatus, commonly known as spoon-leaved milkweed, is a perennial herbaceous plant with attractive white flowers that belongs to the Apocynaceae family. Propagation is the process of reproducing the plants, and Gomphocarpus spathulatus can be propagated by both sexual and asexual means.
Propagation by Seeds
The most common and efficient propagation method of Gomphocarpus spathulatus is through its seeds. The best time to sow the seeds is during the spring season when the soil temperature ranges between 18 and 20°C. Before sowing, the seeds must be scarified to break their outer seed coat. This can be done by rubbing the seeds gently on fine-grit sandpaper or soaking them in hot water for 24 hours. After scarification, the seeds are sown in a well-drained soil mix, covered with a thin layer of soil, and kept moist until germination. The germination period usually takes between 10 to 30 days, depending on the temperature and soil moisture. It is important to note that Gomphocarpus spathulatus is sensitive to transplant shock, so it is recommended to sow the seeds in biodegradable pots or directly in the field.
Propagation by Cuttings
Gomphocarpus spathulatus can also be propagated by stem cuttings. The best time to take cuttings is during the summer season when the plant is actively growing. Select a healthy stem and cut a 10-15 cm long section from it, making sure to remove all the leaves from the lower half of the stem. Dip the cut end in rooting hormone powder and plant it in a well-drained potting mix. Water thoroughly and cover the plant with a clear plastic bag to maintain high humidity levels. Place the cutting in indirect light and remove the plastic bag once roots are visible. It usually takes 3-4 weeks for the cutting to root, and it can then be transplanted into the field or a larger pot.
