Japanese lantern plumeria is a small-growing tree, often growing to about 30 feet high, with an equal width. It is also known as flower basket plumeria because of its large clusters of 3-inch-wide, fragrant, bright-red to medium-red flowers. Japanese lantern plumerias are indigenous flowering plants to Mexico and the Caribbean. For the best growth, plant a Japanese lantern plumeria in full sun and make sure you provide it with slightly acidic soil.
Dig up the planting area for the Japanese lantern plumeria to a depth of between 10 and 12 inches. Spread out over the planting area a 4-to-6-inch-layer of sphagnum peat moss. Then using a garden fork, mix the sphagnum peat moss into the soil thoroughly.
Dig a planting hole, which should be at least twice the diameter of the Japanese lantern plumeria's growing container and just a few inches deeper, approximately 2 to 3. If planting more than one Japanese lantern plumeria, for instance several in a row, dig each hole so they are spaced 10 feet apart from each other.
Remove the Japanese lantern plumeria from its growing container. Turn the pot upside down, hold the stem of the Japanese lantern plumeria at the top of the ball, and strike upward on the rim of the pot to remove the pot from the root ball.
Place a Japanese lantern plumeria into one of the previously dug holes. The Japanese lantern plumeria should be sitting in the planting hole so that the top of its root ball is sitting level to the surrounding garden soil.
Pour water into the planting hole to fill it about three-quarters full. Then fill the remainder of the hole with soil after all the water has thoroughly drained away.
Create a 2-to-3-inch-high dam of soil around each of the Japanese lantern plumeria trees. This can help ensure enough water will pool up and soak down to the root system.
Spread a 3-to 4-inch-layer of coarse mulch, such as pine bark, compost or other like material over the root system of your Japanese lantern plumeria each fall.
