Propagation methods for Michelia doltsopa Buch.-Ham. ex DC.
Michelia doltsopa Buch.-Ham. ex DC., commonly known as the sweet michelia, is a popular ornamental plant that belongs to the Magnoliaceae family. Propagation is the process of growing new plants from different plant parts, and there are different ways to propagate Michelia doltsopa.
Seed propagation
Seed propagation is one of the easiest ways to propagate Michelia doltsopa. The seeds are first collected from the mature fruit and then soaked in water for 24 hours. The soaked seeds are then sown in well-drained soil with a pH range of 5.5-6.5. The seeds should be covered lightly with soil and kept in a shady, humid place until germination occurs. It takes about 2 to 3 months for the seeds to germinate, and the young seedlings must be handled with care during transplanting.
Cuttings propagation
Michelia doltsopa can also be propagated through cuttings. The best time to take cuttings is during the spring season when the plant is actively growing. Softwood cuttings of 10-15 cm in length are taken from healthy and disease-free plants. The bottom of the cuttings is treated with a rooting hormone and planted in well-drained soil. The cuttings should be kept in a warm and humid environment until roots start to form. The process may take around four to six weeks, and once they have established, the cuttings can be transplanted into larger containers.
Air-layering propagation
Air-layering propagation is a method that involves girdling a branch of a mature parent plant and covering it with moss and a rooting hormone. New roots will develop at the girdled portion, and once they appear, the branch can be cut and planted in a separate container. When air-layering Michelia doltsopa, it is important to keep the moss layer moist and not let it dry out. This is a slow process, taking about 6 to 8 months before the branch can be separated from the parent plant.
Disease and Pest Management for Michelia doltsopa Buch.-Ham. ex DC.

To manage leaf spots on Michelia doltsopa:
- Remove affected leaves and dispose of them carefully.
- Spray the plant with an appropriate fungicide.
- Avoid overhead watering as it can promote the spread of the disease.
To manage powdery mildew:
- Remove infected leaves and dispose of them carefully.
- Avoid overcrowding the plants to promote good air circulation.
- Spray the plant with a suitable fungicide.
To manage root rot:
- Avoid overwatering the plant and ensure proper drainage.
- Remove the affected plant and replant in well-draining soil after treating it with a fungicide.
Common Pests of Michelia doltsopa

Pest Management
To manage scales and mealybugs:
- Remove the affected leaves and dispose of them carefully.
- Spray the plant with a suitable insecticide.
- For heavy infestations, use a systemic insecticide that can be absorbed by the plant and transported by its vascular system.
To manage aphids:
- Remove the affected leaves and dispose of them carefully.
