What is the best fertilizer for plumeria?
The quick answer is to look for a fertilizer that is high in phosphorus. This will help it grow those beautiful flowers that we have come to love so much about Plumeria plants. If you use plant food that is high in nitrogen it will grow to be tall and lengthy which isn’t what we want.

How to choose the right fertilizer for plumeria
Caring for plumeria is fairly easy and requires little effort compared to some flowering ornamental, but fertilizing the plants is an important aspect of care to ensure abundant, healthy blooms.
Fertilizers add nutrients to the soil, replenishing what the plant has depleted from the environment over time.
There are fifteen essential for proper plant growth: nitrogen, phosphorus, potassium, calcium, sulfur, magnesium, sodium, boron, chlorine, manganese, iron, zinc, copper, molybdenum and nickel.
They are classified based on the three main elements that are needed in much higher amounts than the others – nitrogen, phosphorus, and potassium – to allow consumers to easily compare one fertilizer product to another.
Nitrogen is listed first on the fertilizer label since it is considered the most key nutrient needed for plant growth. Its main responsibility in the plant is regulating vegetative growth.
Nitrogen is assimilated in the plant into amino acids, the building blocks of protein; it is also a major component of chlorophyll and helps to keep foliage green, and nitrogen is necessary for many of the plant’s enzymatic reactions.
Phosphorus is a structural component in DNA and RNA (the genetic building blocks within plant cells) and is needed for root growth and flowering.
Potassium works more indirectly in plants than nitrogen and phosphorus. While it isn’t a component of any plant parts, it functions by activating the enzymatic reactions that occur, making it imperative for the overall health of the plant.
What Do Plumeria Flowers Need?
When fertilizing plumeria plants, it’s imperative to pick fertilizers that are higher in phosphorus than nitrogen or potassium. A high nitrogen fertilizer will help promote a healthy plant, but it will spur vegetative growth causing the tree to become tall and leggy.
Fertilizers higher in phosphorus will promote blossom development, which is the end goal with plumeria.
There are many fertilizer options available for purchase, including both conventional fertilizers or organic products.
An all-purpose fertilizer geared towards a wide range of plants or products specifically formulated for flowering plants can also be just as effective.
Lastly, both granular or liquid formulations can be used to promote great looking flowers.
These options allow gardeners to choose products that fit their budget, and gardening philosophy.
Plumeria plants – as well as other tropical flowering ornamentals – have many fertilizers formulated specifically to their needs making it somewhat easier for the homeowner to find a suitable product.
When looking at plumeria options water-soluble fertilizers should have a phosphorus content greater than 50 in the N-P-K ratio, granular fertilizers should be higher than 20.
This will help to facilitate the most blossoms on the plant.
