Plumerias (also called Frangipani) are tropical, flowering trees highly valued for their fragrant blossoms, which are often used in bridal bouquets or leis. In the wild, the trees can grow up to 30 feet tall, according to information published by the National Gardening Association. In the home garden, these trees are kept short by pruning or by choosing smaller varieties. Plumerias are hardy, beautiful plants that require only basic culture.
Plant your plumeria where it will receive either full sunlight or a small amount of light afternoon shade, such as dappled shade.
Amend the soil with organic mulch, if needed. Choose a location in the garden that is well-draining. Plumerias need well-draining soil in order to survive, according to information published by the National Gardening Association. Overly wet soil will cause root rot, a fungal disease. Never plant the tree where standing water collects or where flooding occurs.
Water enough so that the plant receives about one inch of water per week. These trees need a lot of water, according to information published by the National Gardening Association, and container plants may need even more water than plumerias planted in the ground. Still, do not over-water, or root rot will develop.
Fertilize your plumeria every other week with a fertilizer high in phosphorous (10-20-30) during the growing season (spring through summer). Apply the fertilizer according to the directions on the label for the size of your tree.
Monitor the tree for common insect pests such as mites and scale. Treat with an insecticidal spray if necessary.
