Plumeria is a tropical flowering shrub, but most people consider it as a flower, since the fragrant blooms are so well-known for creating leis in Hawaii. Plumeria grows best in a temperate outdoor climate, in a hot, dry location that is in full sun. If you live in a very hot or dry climate, you can plant them in an area with partial shade.
Plant plumeria in the spring.
Prepare the planting soil. Plumeria need to be planted in soil that drains well and fast. Although the plant isn't too picky about the soil, it cannot be cold or constantly wet. Mix up some organic compost or crushed lava rock to add to poor soil conditions.
Space the plumeria holes about ten to fifteen feet apart. Use a shovel to dig a hole as deep as the plumeria's root ball and two to three times as wide.
Remove the plumeria plant from the container it came in, and carefully place it in the hole. Fill the hole half full with soil, then water it generously in order for the plumeria to settle in the soil and get to rid of any air pockets.
Let the water drain out. Fill up the rest of the hole with soil and pack it down securely around the plumeria roots and base. Water the plant generously so it can settle into the soil some more.
