Plumeria, also called frangipani, is a tropical plant native to Mexico, Central America and Asia. It grows as a small tree with gracefully angled branches that reach up to 25 feet tall. When your plumeria will bloom depends on the age of the tree, the season of the year and the amount of light, water and fertilizer its had.

About Plumeria

The plumeria tree bears elongated oval leaves and attractive flowers that come in a variety of colors, from white to yellow to fuchsia pink. Because plumeria is a plant that grows in tropical and sub-tropical regions, ensure that you imitate the warm, humid conditions to allow your tree to grow and blossom. Plumeria is hardy down to 33 degrees Fahrenheit. Protect the tree with mulch and landscape cloth if temperatures remain below this for several days. Plumeria can also be ground indoors under growlights. The pot should be large enough to act as a ballast so the plant does not tip over as it grows taller.

Plumeria Care

Plant your plumeria in an area that gets full sun for at least half the day. Plant in soil that drains well. If necessary, add organic material like peat moss or compost to assist drainage. Water generously during dry periods. Withhold water during the plant's dormant period, from December through March. Plumeria requires fertilizer that is high in phosphorus (the P number on the fertilizer bag). Fertilize every two weeks during the growing season and not at all in the dormant season. Spray weekly with insecticidal soap if pests are present. Prune broken or misshapen branches from the tree at any time of the year, although winter is the best time.

Plumeria Bloom Times

Generally, small plumeria seedlings will not bloom until the tree is three years old, but they may bloom sooner if conditions are right. Plumeria will bloom throughout the summer months in the northern hemisphere if given the basic conditions that they need for blossom production. Pruned branches may see a delay in blooming. Mature, established trees withstand pruning without a reduction in blossom production. Plumeria trees will drop leaves and rest in between bloom periods.

Blooming Problems

If your Plumeria does not bloom, move the tree to a location with more sunlight. Increase fertilizing with a high-phosphorus plant food. Water the tree as soon as the surface soil becomes dry. Plumeria also need repleshment of micronutrients like copper, boron, magnesium, calcium and sulfur. Plant supplements with these additional nutrients that are available at garden centers and plant nurseries.
