How to grow and maintain Plumeria rubra:
Plumeria grows best in bright light to full sun. Keep Plumerias plant at least 6 hours a day.
Plumeria grows best in well-drained soil. Use peat moss based potting mix. It prefers the soil pH around 6 to 6.7 (slightly acidic). They endure a wide variety of soils, from acid to alkaline and sandy to clay.
It requires average to warm temperature between 65°F – 80°F / 18°C – 27°C. It will endure high temperatures, but if you move it outdoors for the summer, bring it back inside if the temperature drops below 55°F / 13°C at night.
Water regularly during the growing season and always keep the soil moist but never allow your plant to sit in water. During the winter season, reduce watering and you can allow the topsoil to become slightly dry between each watering.
Fertilize Plumeria rubra plants twice a month during the growing season with high-phosphorus fertilizer to promote blooming.
It is very easy to propagate from seed or by cutting. In spring or fall, cut the stem tips one to two feet long and allow the cut ends to dry for a week, to prevent the sap from oozing out, before planting in the potting medium.
