Propagation of Bequaertiodendron natalense
Bequaertiodendron natalense (Sond.) Heine & J.H.Hemsl. is propagated through several methods including seed, stem cuttings, and air layering.
Seed Propagation
The easiest method of propagating Bequaertiodendron natalense is through seed. The seeds should be collected from the fully mature fruit, which appears as a woody capsule, and sown in seed pots filled with potting mix.
Seed pots should be kept in a bright location with temperatures around 25°C. Germination should occur within 4-6 weeks. Seeds can also be sown directly outside during the summer months.
Stem Cuttings
Stem cuttings can be taken from the parent plant during the spring or summer months. Cuttings should be about 10-15cm long and taken from semi-mature wood.
A rooting hormone should be applied to the bottom of the cutting and inserted into a pot filled with a well-draining potting mix. The pot should be placed in a bright, warm location and watered regularly. Roots should develop within 6-8 weeks.
Air Layering
Air layering is another method of propagating Bequaertiodendron natalense. This method involves selecting a healthy branch on the parent plant and removing a ring of bark about 1-2cm wide from around the stem.
The exposed area should be packed with a moist sphagnum moss or peat moss mixture and then wrapped with plastic wrap to keep the area moist. Roots should develop within 6-8 weeks, and once they have formed, the new plant can be cut from the parent plant and potted in well-draining potting mix.

Bequaertiodendron natalense is a fairly hardy plant that is relatively resistant to pests and diseases. However, it is not immune to certain conditions that may adversely affect its overall health and appearance.
Common Diseases
One of the most common diseases affecting Bequaertiodendron natalense is powdery mildew. This fungal infection is characterized by a white, powdery substance that appears on the leaves and stems of the plant. The leaves may also become distorted and yellowed.
To manage this condition, it is important to promptly remove any affected leaves and plant debris. Treat the plant with a fungicide specifically formulated for powdery mildew, following the manufacturer's instructions closely. Additionally, ensure that the plant is not overly crowded, and that there is good air circulation around the foliage.
Another fungal disease that can affect Bequaertiodendron natalense is anthracnose, which causes dark lesions and spots on the leaves and stems. Infected leaves may also become distorted or fall prematurely from the plant.
To manage this condition, it is important to remove any infected plant debris to prevent the spread of the disease. Fungicides can be applied to affected areas, and plants should be watered at the soil level to avoid getting the leaves wet.
Common Pests
Bequaertiodendron natalense is also susceptible to certain pests, including scale insects and spider mites. These pests can cause damage to the leaves and stems of the plant, and may even lead to eventual death if left untreated.
For scale insects, it is important to remove any affected plant parts and wash the plant with a gentle soap solution to remove the pests. Spraying the plant with insecticidal soap can also help manage infestations.
Spider mites can be managed with regular applications of neem oil or insecticidal soap. It is also important to maintain proper watering habits, as spider mites thrive in hot, dry conditions.
Overall, the best way to manage pests and diseases on Bequaertiodendron natalense is to maintain a healthy plant with proper watering, fertilization, and pruning practices. Regularly inspecting the plant for signs of pest or disease activity and quickly addressing any issues can also help ensure a healthy, thriving plant.
