Propagation of Plumeria africana Mill.
Plumeria africana Mill. can be propagated by various methods, including:
Seed Propagation
Propagation through seeds is the most common method to propagate Plumeria africana Mill. However, since the seeds are small and hence do not store well, it is recommendable to sow the seeds soon after harvesting.
First, the seeds must be removed from the parent plant’s pod and given a good wash with water. Soak the seeds in warm water for about 24 hours before planting them. When planting, cover the seeds with soil to about 2 inches deep. Keep the soil moist, and sprouting usually occurs between 1 to 2 weeks after sowing the seeds.
Stem Cuttings Propagation
Plumeria africana Mill. can be propagated with stem cuttings. This method of propagation has a higher success rate of producing new plants that are similar to the parent plant. Propagation through stem cuttings can be easily done throughout the year. However, the best period to take the cuttings is during the growing season.
Choose a healthy branch from the parent plant with no signs of diseases or pests. The cutting should measure about 30-45cm in length and have no flowers or buds. Cut an angle at the bottom of the selected branch and treat the lower end with rooting hormone before planting in the soil. The prepared stem cutting should be planted in well-draining soil and placed in a shaded area and watered regularly. Rooting of the cuttings may occur within 4 to 6 weeks.
Grafting Propagation
Grafting is an excellent propagation method to increase the success of budding, flowering, and fruiting. The most suitable method of grafting Plumeria africana Mill. is by using lateral veneer grafting or V-grafting. This method involves cutting a wedge in the stock plant and then removing a matching wedge from the scion plant. The scion is patched over the wedge of the stock plant and tied securely to the grafting point using rubber or plastic strips. After two to three weeks, the joining of the stock and scion should be secure.
Propagation of Plumeria africana Mill. will likely help gardeners have more of these beautiful plants in their garden or landscape. However, it's important to ensure all propagating materials are clean and disease-free. That way, the new plants will grow healthy and continue to bloom gloriously for years to come.

- Mealybugs - tiny, white insects that leave a powdery residue on the plant and cause stunted growth and yellowing of the leaves.
- Scale insects - small, brown insects that attach themselves to the leaves and stems and suck the sap from the plant, causing yellowing and death of the leaves.
To manage pests on Plumeria africana, it is recommended to:
- Inspect the plant regularly for signs of infestation and remove any affected leaves or flowers.
