The cuttings should be watered regularly, and rooting usually occurs within 3-4 weeks.
Propagation by Division
The root clumps of Humularia kapiriensis (De Wild.) P.A.Duvign. var. kapiriensis De Wild. can be divided, and the individual clumps can be planted in separate containers. Dividing should be done during the active growth period, and the soil should be kept moist after planting. This method is usually more successful than sowing seeds, and the new plants will begin to grow within a few weeks.
Disease and Pest Management for Humularia kapiriensis
Humularia kapiriensis is a hardy plant that is not typically plagued by diseases or pests. However, it is still essential to keep an eye out for any potential issues and take immediate action to prevent them from spreading.

One of the most common diseases that can affect Humularia kapiriensis is root rot. This disease is caused by overwatering the plant or poor soil drainage. To prevent root rot, ensure that the plant is not sitting in water and that the soil has proper drainage. If root rot has already set in, the affected roots should be trimmed off, and the plant should be repotted in fresh, well-draining soil.
Leaf spot is another disease that can affect Humularia kapiriensis. This disease is typically caused by fungal infections, which can be prevented by ensuring that the plant is not overwatered and that water is not allowed to sit on the leaves for extended periods. If your plant exhibits signs of leaf spot, you can try treating it with a fungicide.
Pests
Humularia kapiriensis is not commonly affected by pests. However, spider mites can occasionally infest the plant if conditions are too dry. These pests can be managed through regular misting of the leaves and stems. If the infestation is severe, insecticidal soap can be used to kill the mites.
Mealybugs can also affect Humularia kapiriensis. These pests can be identified by the white, cottony masses that they leave on the plant.
