Propagation of Selago cordata E.Mey.
Selago cordata E. Mey., commonly known as Heart-leaf Buchu, is a small shrub that is native to South Africa. The plant is much valued for its medicinal properties and aromatic scent. Propagation of this plant can be done through different methods, some of which are outlined below.
Seed Propagation
Propagation of Selago cordata can be done through seeds. The seeds are sown in a suitable seedling medium and kept under controlled conditions until germination occurs. After germination, the seedlings can be transplanted into larger containers or directly into the soil. It is important to keep seedlings watered and to protect them from pests until they are established.
Cuttings Propagation
Selago cordata can also be propagated through cuttings. The best time to take cuttings is in early spring or late summer. Cuttings should be taken from healthy, disease-free plants. They should be about 3 to 4 inches long and should include a few leaves. Cuttings should be dipped in rooting hormone before planting in a suitable rooting medium. The cuttings will establish roots in about three to four weeks.
Division Propagation
Division of mature Selago cordata plants is another method of propagation. This method involves dividing the plant into smaller sections during the dormant season. The divided sections can then be transplanted into suitable containers or directly into the soil. It is important to keep the divisions watered and to protect them from pests until they are established.
Propagation of Selago cordata can be done through different methods, and each method has its own advantages and disadvantages. The best method for propagation depends on the availability of materials and the preference of the grower.

Another disease that can affect Selago cordata is fungal leaf spots caused by high humidity levels, damp conditions and overwatering. The best management approach is to remove and destroy affected leaves and stems immediately and reduce watering frequency.
Bacterial leaf blight may infect Selago cordata under poor conditions of humidity and high soil moisture levels. Cut off all the infected tissues and discard them, and treat the plant with copper sprays.
Common Pests of Selago cordata
Insects are common pests that may attack Selago cordata and cause damage to the foliage, resulting in slowed growth or death of the plant. Common pests include spider mites, whiteflies, and mealybugs.
Spider mites are tiny pests that suck the sap of the plant, causing the foliage to become discolored. Applying insecticidal soap or oils will help control spider mites. Whiteflies are small, winged pests that feed on the sap of the plant, causing leaves to turn yellow. Use insecticidal soap or oils to eliminate whiteflies, treating the plant weekly until all the pests are gone. Mealybugs attack the leaves and stems, sucking plant juices, causing the foliage to become weak and stunted. The use of neem oil can be helpful in controlling mealybugs.
In summary, proper disease, and pest management for Selago cordata involves keeping the roots and leaves healthy by observing the right conditions that match its needs and knowing how to respond in case of any issues. With effective plant care, your Selago cordata plant can thrive, and you can enjoy it for long periods.
