- Sowing: Sow the seeds in moist, well-draining potting mix and place them in a warm, sunny location.
- Germination: Expect seeds to germinate within 2-4 weeks.
2. Cuttings Propagation:
- Selecting cuttings: Take semi-hardwood cuttings, about 4-6 inches long, from the current year’s growth.
- Preparation: Remove the lower leaves and make a diagonal cut at the base of the cutting.
- Rooting hormone: Dip the cut end of the cutting in rooting hormone for optimal success.
- Planting: Insert the cuttings in a mixture of rooting hormone and perlite or vermiculite, keeping them moist but not soggy.
- Care: Cover the cutting with a clear plastic dome or bag to create a humid environment. Roots should develop within 4-6 weeks.
3. Air Layering:

- Preparation: Gently scrape a small section of bark, exposing the cambium layer. Wrap this area with moist sphagnum moss and secure it with plastic wrap.
- Root development: Maintain moisture within the moss and monitor the wrapped section regularly. Roots should form within a few months.
- Separation: Once roots have formed, you can cut below the air layering, leaving the new plant attached to its root system.
Tips for Success:
- Sunlight: Ensure your cuttings and seedlings receive ample sunlight.
- Moisture: Maintain consistent moisture levels, but avoid overwatering.
