The minimum temperature for planting plumeria outdoors is typically around 50°F (10°C). Plumerias thrive in warm climates, and temperatures below this can cause them to go dormant or can potentially damage the plant, especially young or newly planted specimens. For optimal growth, plumerias prefer temperatures between 65°F (18°C) and 80°F (27°C). If you anticipate colder temperatures, it’s best to wait before planting or ensure you have measures in place to protect the plant, such as bringing potted plumerias indoors or using protective covers for outdoor plants.
