Division
Another method of propagating Cephalostigma hookeri is through the division of mature plants. The plant should be carefully removed from the soil and divided into small sections, ensuring that each division has a healthy root system and several leaves. The divisions should then be potted in a well-draining soil mixture and kept moist until new growth appears.
Cuttings
Cephalostigma hookeri can also be propagated through stem cuttings. Take a 10cm long cutting from the tip of a healthy stem, ensuring that it has at least two nodes. Remove the leaves from the bottom half of the cutting and place it in a pot containing a well-draining soil mixture. Water the cutting regularly and keep it in a warm, humid place until new growth appears.
Propagation of Cephalostigma hookeri is relatively easy and can be done with minimal effort. With proper care and attention, the newly propagated plants will mature to their full size in no time, providing an exotic addition to any garden.
Disease and Pest Management for Cephalostigma hookeri C.B.Clarke

Like all plants, it is susceptible to diseases and pests. Identifying the signs of disease and pest infestation and taking corrective measures in a timely manner can help maintain the plant's health and vitality. Here are some common diseases and pests that might affect the Cephalostigma hookeri C.B.Clarke plant and ways to manage them.
Common Diseases
Leaf spot: Leaf spot is caused by fungal pathogens and appears as circular or irregular-shaped brown or black spots on the leaves. The affected leaves may eventually fall off, leading to defoliation. To manage leaf spot, prune and dispose of any infected leaves. Avoid overhead watering and water at the base of the plant. Apply a fungicide as a preventive measure.
Powdery mildew: Powdery mildew appears as a white powdery substance on the foliage and stems. It thrives in humid conditions and can stunt plant growth. To manage powdery mildew, remove and dispose of any infected leaves, provide proper air circulation and light exposure, and apply a fungicide as per the manufacturer's instructions.
Root rot: Root rot is caused by overwatering, poor drainage, or fungal pathogens. The affected plant may exhibit wilting, yellowing of leaves, and root decay. To manage root rot, prune the affected roots, trim the foliage, and replant the plant in fresh soil with good drainage. Avoid overwatering and water at the base of the plant.
Common Pests
Aphids: Aphids are sap-sucking insects that cause stunted plant growth, yellowing of leaves, and honeydew secretion. To manage aphids, wash them off with a hose or apply insecticidal soap as per the manufacturer's instructions. Introduce natural predators like ladybugs or lacewings to help control aphid infestation.
Spider mites: Spider mites are common pests that prefer dry conditions and can cause yellow stippling on the leaves. To manage spider mites, wash the plant with a hose or shower, prune affected leaves, and apply a miticide as per the manufacturer's instructions. Maintain adequate humidity and avoid over-fertilizing the plant.
Scale insects: Scale insects are small, oval-shaped insects that suck plant sap and reproduce rapidly. They can cause the yellowing of leaves, sticky residue, and the decline of plant health. To manage scale insects, remove them by hand, prune affected leaves, and apply insecticidal soap or horticultural oil as per the manufacturer's instructions.
Regular monitoring, maintenance, and early intervention can help keep Cephalostigma hookeri C.B.Clarke healthy and flourishing for years to come.
