How to Grow and Care
Although you don't have to live in the tropics to grow Plumeria in the home garden, you should know its growing requirements beforehand.
Often grown in the garden as an ornamental shrub or small tree, Plumeria plants need to be grown in well-draining, slightly acidic soil. They also need at least six hours of full sun.
While the plants are fairly tolerant of salt and windy conditions, they're not tolerant of cold and must be protected. Therefore, they should be container-grown in colder regions. In areas that may be warm most of the time but are still fairly prone to cold winters, the plant can be dug up and overwintered indoors. Alternatively, you can sink container-grown Plumerias in the ground, bringing them indoors once the temperatures begin to drop in fall. Then, once warmer temps return in spring, you can return the plants back outdoors.
When growing Plumeria plants in pots, use a coarse, well-draining potting mix—cactus mix or perlite and sand should be fine.
