Care for plumeria, a type of tropical plant, by planting it in a sunny location, using well-drained soil, and watering it often. Plant the plumeria in the spring in a location that not only has access to plenty of sunlight and light shade, but also gives the tree plenty of room to grow; plumeria can reach up to 30 feet tall. There are shorter, hedge-like varieties from which to choose that grow bushy rather than tall.
Unless you live in a warm southern climate that doesn't get cold enough for a frost, plant the plumeria in a container you can take inside during winter weather. Use well-drained, slightly acidic potting mix such as that produced for cacti. If planting the plumeria in the ground, dig a hole that is at least twice the size of the rootball, and add a little compost before setting the roots inside.
Water the plant well immediately after planting, and continue to water it regularly, giving it at least 1 inch of moisture per week; use more for potted plants. Fertilize the plants using high-phosphorus plant food every other week during the growing season. Trim off any dead or damaged limbs in the early spring.
