Plumerias are lush tropical plants that typically grow as small trees. They bloom with extremely fragrant flowers that range in color from white and yellow to pink and red, and are often used to make Hawaiian leis. With thick, trunk-like stems and large, leathery leaves, plumerias add beauty both to the home landscape and indoors. Plumerias do well in containers as house plants because these tropical plants enjoy the environmental conditions created indoors.
Pot your plumeria in a container large enough to accommodate the roots and with drainage holes in the bottom. Plant the plumeria in an organic, fast-draining potting mixture, setting it at the same depth that it was planted in the nursery container.
Position your plumeria in a sunny spot in your house, such as beside a south-facing window. Set the plumeria outdoors during the warmer months to provide it with about four hours per day of direct sunlight.
Water your plumeria once every three or four days when the plant has flowers and leaves, providing water until it drains from the bottom drainage holes in the pot. Water the plumeria daily during the hottest part of the summer.
Feed your plumeria with a high-phosphorous fertilizer, such as a 10-15-10 NPK formula or rose fertilizer, once every two weeks while the plant is actively growing. Follow the instructions on the label for proper dosage.
Prune your plumeria in spring to shape the plant. Prune away any damaged or dead growth during the year.
