The fertilizer should be applied according to the manufacturer's instructions. Overfertilization can lead to burned roots and leaves, so be careful not to use too much.
Pruning
Peliostomum marlothii Engl. requires minimal pruning. The only pruning needed is to remove dead or damaged leaves. The plant may also require some shaping if it becomes too leggy.
Pruning should be done in the spring before the growing season begins. Use sterilized pruning shears, and make sure to clean them between cuts to prevent the spread of disease.
Propagation of Peliostomum marlothii Engl.
Peliostomum marlothii Engl. can be propagated through both seeds and cuttings.
Propagation through seeds:
The plant produces small, globular capsules containing numerous tiny seeds. To propagate Peliostomum marlothii through seeds, the capsules must be picked when they are ripe and placed in a dry, well-ventilated area for a few days. After that, the capsules can be opened to collect the seeds. The seeds should be sown in well-draining soil mix and kept moist until germination, which can take up to two weeks.
Propagation through cuttings:
Peliostomum marlothii can also be propagated using semi-hardwood cuttings, which should be taken in late spring or early summer. The cuttings should be about 10 cm long and have at least three nodes. Leaves from the lower nodes should be removed, and the stem should be treated with rooting hormone powder before planting in a well-draining soil mix. Cuttings should be kept moist and in a warm, shaded area until rooted, which can take up to eight weeks.
Disease and Pest Management for Peliostomum marlothii Engl.
Peliostomum marlothii Engl., commonly known as the bushveld sage, is a small evergreen shrub that is native to southern Africa. This plant is resistant to many diseases and pests, but it is not immune to them. Proper plant care, including regular watering and fertilization, can help prevent infestations and infections.
Common Pests
The most common pests that may affect Peliostomum marlothii are mealybugs, spider mites, and scale insects. These pests can cause damage to the foliage and weaken the plant.
Mealybugs: Mealybugs are small, white, fluffy insects that thrive on the leaves and stems of Peliostomum marlothii. To manage mealybugs, you can wipe them off by hand or use insecticidal soap. You can also introduce predators, such as ladybugs or lacewings, to control the population.
Spider Mites: Spider mites are tiny pests that suck the sap from the leaves of the bushveld sage plant. They are difficult to detect, but their presence can be detected by their web-like structures on the leaves. You can control spider mites by spraying the plant with neem oil or insecticidal soap. You can also introduce predatory mites, such as Phytoseiulus persimilis, to control their population.

To control scale insects, you can wipe them off or use insecticidal soap. You can also introduce predators, such as parasitic wasps or lady beetles, to control their population.
Common Diseases
Peliostomum marlothii is susceptible to several fungal and bacterial diseases. These diseases can be caused by poor plant care, such as overwatering or poor drainage.
Crown rot: Crown rot is caused by the fungus Phytophthora cinnamomi. It is characterized by wilting and discoloration of the foliage near the base of the plant. To manage crown rot, you can apply a fungicide to the soil around the plant. You can also improve drainage by adding organic matter to the soil.
Leaf spot: Leaf spot is caused by the fungus Cercospora sp. It is characterized by circular, dark spots on the foliage of the plant. To manage leaf spot, you can remove infected leaves and apply a fungicide to the plant. You can also improve air circulation by pruning the plant.
Root rot: Root rot is caused by the fungus Rhizoctonia solani. It is characterized by brown, mushy roots and stunted growth. To manage root rot, you can improve drainage by adding organic matter to the soil. You can also remove infected roots and apply a fungicide to the soil.
Overall, prevention is the best strategy for managing pests and diseases in Peliostomum marlothii Engl. Regular monitoring of the plant, proper plant care, and the use of natural predators and fungicides can help keep the plant healthy and thriving.
