Why Won't My Plumeria Bloom?

According to HGTV, plumerias are very sensitive plants that require specific conditions to grow properly. Plumerias are tropical plants that grow and bloom best with full sun exposure.

The plumeria needs full sunlight and the right amount of fertilizer in order to bloom annually. HGTV recommends using a compost tea as a fertilizer and keeping the soil around plumeria plants relatively dry. Plumerias grow best in Zone 10, an area with average extreme low temperatures around 30 to 40 degrees Fahrenheit. The plumeria will stop producing leaves and blooms at around 40 to 50 degrees Fahrenheit. HGTV recommends avoiding watering or fertilizing plants during winter months, but it is important to keep the plant indoors in a warm location. Replant the plumeria into a larger container as needed to ensure the plant has plenty of space to promote bloom formation in the spring.
