Remove the leaves from the bottom few inches of the stem and dip the cut tip into rooting hormone. Then, plant the stem in a well-draining soil mix. Keep the soil moist and in a warm, sunny area, and the plant should start to grow new roots within a few weeks.
Propagation by Division
Sphenogyne brachyloba Kunze can also be propagated by division. This method involves digging up the parent plant and splitting it into several smaller ones. Make sure each division has several stems and roots. Plant the new divisions in fresh soil and water adequately. Keep the soil moist and in a warm area, and the plants should start to grow within a few weeks.
Conclusion
Sphenogyne brachyloba Kunze is an easy plant to propagate. It can be done by seeds, cuttings, and divisions. Regardless of the method chosen, it is essential to keep the soil moist and in a warm, sunny area. With proper care, the new plants should start to grow within a few weeks.

Another disease that may affect Sphenogyne brachyloba Kunze is root rot. Root rot is a fungal disease that affects the roots of plants, causing them to turn brown and mushy. To prevent root rot, it is important to avoid overwatering and to ensure that the soil has good drainage. Treating with a fungicide may also be necessary in severe cases.
Common Pests
Aphids are one of the most common pests that may affect Sphenogyne brachyloba Kunze. These small, soft-bodied insects feed on the sap of plants and can cause stunted growth and yellowing of leaves. To control aphids, spraying the plant with a solution of water and soap or neem oil may be effective.
Spider mites may also be a problem for Sphenogyne brachyloba Kunze. These tiny pests feed on the leaves of plants, causing them to turn yellow and dry out. To control spider mites, washing the plant with a strong jet of water or treating with insecticidal soap may be effective.
Overall, maintaining a healthy plant by providing proper sunlight, water, and nutrients is the best way to prevent and manage diseases and pests in Sphenogyne brachyloba Kunze.
