Propagation of Eriosema populifolium Benth. ex Harv. subsp. populifolium
Eriosema populifolium Benth. ex Harv. subsp. populifolium can be propagated through seeds, stem cuttings, and division.
Propagation through Seeds
The seeds of Eriosema populifolium Benth. ex Harv. subsp. populifolium can be sown in seedbeds or pots filled with well-draining soil mix. The seeds need to be placed on the surface of the soil and not covered as they require light for germination. Water the soil regularly and keep it moist. The seeds will germinate in a few weeks.
Propagation through Stem Cuttings
Eriosema populifolium Benth. ex Harv. subsp. populifolium can be propagated through stem cuttings. Select healthy and disease-free stem cuttings of 10-15 cm in length. Remove the lower leaves and dip the cut end of the stem in rooting hormone powder. Place the cuttings in a well-draining soil mix and water the soil.

Propagation through Division
Eriosema populifolium Benth. ex Harv. subsp. populifolium can be propagated through division. Dig up the plant during the dormant season and separate the roots into smaller sections. Each section should have a healthy shoot and some roots. Replant the sections in a well-draining soil mix and water the soil. Keep the soil moist until the plant is established.
Disease Management for Eriosema populifolium Benth. ex Harv. subsp. populifolium
Eriosema populifolium Benth. ex Harv. subsp. populifolium is not known to be highly susceptible to diseases. Yet, there are a few diseases that might affect the plant, especially if there are unfavourable climatic conditions or poor cultural practices.
Brown spot, one of the most common diseases of this plant, is caused by a fungus. The initial symptom of the disease is the appearance of small, dark-brown spots on the leaves that gradually increase in size and merge together. Infected leaves usually die and fall off. To manage brown spot, prune the infected leaves and improve the plant's cultural conditions, such as soil drainage and air circulation.
Another disease that might affect Eriosema populifolium Benth. ex Harv. subsp. populifolium is root rot caused by soil-borne fungi. The disease leads to yellowing of leaves and stunted growth and often damages the plant severely or even causes death. To manage root rot, avoid overwatering and poorly drained soils.

To prevent spider mites, maintain a low humidity level and avoid over-fertilization. Spray the plant's leaves with water regularly to keep them clean and dust-free. If necessary, treat the plant with an insecticide or miticide.
Cutworms are another potential pest that might damage Eriosema populifolium Benth. ex Harv. subsp. populifolium. These caterpillars usually cut the seedlings at the base, causing death.
