- Dip the basal end of the stem into rooting hormone powder.
- Plant the stem cutting in a well-draining potting soil.
- Water the soil to keep it moist, but not waterlogged.
- Place the pot in a shaded area, away from direct sunlight.
- Roots should appear within one to two months.
Layering
Another propagation method for Penianthus patulinervis Hutch. & Dalziel is layering. Follow the procedure below:

One of the most common diseases that can affect Penianthus patulinervis is leaf spot. This typically appears as small brown or black spots on the leaves, which can eventually cause the leaves to wither and die. To manage this disease, it is important to remove and destroy any infected leaves as soon as they are noticed. Additionally, it may be helpful to treat the plant with a fungicide to prevent the disease from spreading further.
Another common disease that can affect Penianthus patulinervis is root rot. This occurs when the roots of the plant become infected with a fungus, causing them to rot and eventually leading to the death of the plant. To manage root rot, it is important to ensure that the plant is not over-watered and that the soil is well-drained. Additionally, treating the plant with a fungicide can help to prevent the spread of the disease.
