Plumerias are tropical plants grown for their traditional Hawaiian lei blossoms, which are used in garlands and bouquets, and for their exquisite scent. Plumerias are also known as frangipani plants.
In addition to their alluring aroma, one of the primary factors contributing to their popularity is that they are resistant to a wide range of pests and need the use of high-quality fertilizers to flourish and improve their aroma.
The ideal fertilizer is the one that has a greater concentration of phosphorus than nitrogen and potassium. In addition, the best fertilizer for plumeria plants will include a variety of extra macro and micronutrients.
Plumerias are plants that have sturdy roots when they are grown in their native hardiness zones and are cultivated there. Because of the confinement, it may be difficult for them to bloom in pots, even in a tropical setting. The best fertilizer for Plumeria should have both macronutrients and trace elements, such as zinc, iron, manganese, and boron.
Micronutrients include calcium, magnesium, and sulfur. Furthermore, macronutrients include trace elements. They all positively impact plant health, notwithstanding the differing degrees to which they are included in a given formulation.
The Best Fertilizers That Are Most Effective For Plumeria
Phosphorus is essential for the growth of plumeria plants, which is why the middle number on fertilizer labels is given such importance. Phosphate-rich fertilizer should be given to your plumeria plants in order to encourage them to flower. In addition, you need to stay away from fertilizers that contain a lot of nitrogen since the first number on the packaging represents that component.
You should search for a component that has a healthy NPK ratio and high-quality individual parts. Fertilizing a garden on a recurring basis, on the other hand, might result in the accumulation of acid in the soil at levels that are potentially hazardous.
If the nitrogen content of the plant’s food is low, the diet will not stimulate the development of the plant’s leaves. The following are examples of some of the most effective fertilizers for Plumerias.
1. Flower Fuel 1-34-32 – Bloom Booster by Element Nutrients
For your plumeria, this is one of the best alternatives, despite its higher cost. This formulation is low in nitrogen, making it ideal for flowering plants like your plumeria. As a result, your plumeria will be able to focus more on producing flowers rather than growing leaves as a result of using this formulation.
Because it is water-soluble, it is beneficial to the plant throughout its whole life cycle, from the smallest cuttings, which may be grown in water, to the largest bushes.
Flower Fuel is a bloom fertilizer that is totally soluble in water and is designed specifically for use in hydroponic systems. It may be used in any soil, coco, hydroponic, or aeroponic system with any base nutrient, including all major two-part and three-part fertilizers.
Aeroponic systems are not compatible with this product. That is the one and only disadvantage: it is very concentrated.
Over 40 different kinds of flowers and plants go into the creation of flower fuel. These potent fertilizers include all of the trace elements that are necessary for the growth of healthy plants and are available to the gardener.

2. Scotts Turf Builder WinterGuard Fall Lawn Food
Scotts Turf Builder WinterGuard Autumn Lawn Food is best sprayed in the fall. To ensure a more vibrant colorful plumeria, it grows strong and deep roots. This slow-release granular treatment helps feed your plumeria over the winter months since roots continue to grow during dormancy. As a consequence of summer’s heat, dryness, and activity, lawns are damaged and need nutrients in the fall to fix them.
This is a fantastic choice for anybody who wishes to be more accurate in addressing seasonal plumeria needs without having to put in too much effort to learn about the different species of plumeria they have.
Despite this, sandy soils may not hold as much nutrition as other types owing to the higher chance of leaching.

5. Humboldt’s Secret Flowering Flower Stacker
This fertilizer is suitable for use in the cultivation of any plant. Your plumerias are covered with an incredible number of blossoms. Even newly harvested transplants might stand to gain from using the 0-7-5 formula. Due to the fact that it is liquid, it will not harden into a crust on the soil, which will prevent your plumeria from properly absorbing nutrients.
Because it is of hydroponic quality, you may use it to start new plants from cuttings in water. This would work well for a plant kept indoors. Only one of these little bottles may provide at least 29 gallons of the finished product. The mild nutritional profile and the convenience of the little bottle make it an excellent choice for a plumeria that is grown in a container.
However, the lack of nutritious value is the most significant downside. It’s possible that this is too light for a plant that’s used to being fertilized with a heavier substance, in which case you should look for something more substantial.
- NPK ratio: 0-7-5
- Liquid fertilizer
- High phosphorus and potassium content
- Is high in nutrients with b1
- Improve yields by up to 30%
Direction for Usage:
After shaking the bottle, measure out between 3 and 8 milliliters for each gallon of water. Pour Flower Stacker into a full watering can or reservoir and swirl to completely blend. For best results, apply to the root zone and feed with each or every watering starting in the third week of flowering.

6. Nelson Plumeria Plant and All Flowering Tropical Food
Nelson has long been regarded as the most superior plumeria feed available on the market due to its 5-30-5 NPK composition, exceptional slow-release granules, and one-time annual application. There’s a good reason why it’s been around for such a long time.
However, it’s the plumeria feed that sells the most. The usage of this NPK fertilizer, which has a ph. of 5-30-5, is very beneficial to the cultivation of plumeria flowers.
The NutriStar from Nelson is effective for tropical plants since it modifies the soil under perfect growing conditions. Iron has an important role in the formation of chlorophyll and the process of respiration in plants.
Last but not least, calcium plays a role in the formation of the cell walls of plants. In spite of the fact that it is designed specifically for plumerias, the inappropriate use of this inorganic fertilizer has the potential to cause damage to the plants.
There is a possibility that both youngsters and pets will pose a danger.

Frequently Asked Questions:
Depending on the kind and quantity of fertilizer used, it is suggested to fertilize once every two to four weeks throughout the growing season. For MiracleGro, you only need to apply for it once a month. For granular fertilizers, you should do so every six weeks.
If your Plumeria isn’t producing leaves, it might be a sign of water or nutritional stress. Pre-dormancy or faux dormancy may occur in plumerias and other succulents if they are underwatered or deficient in nutrients. This means that the plants will stop blooming and begin to lose their leaves.
A well-balanced time-release fertilizer may be used for overall plant health, although a higher phosphorus content can help with flowering. Despite the fact that this is one of the reasons why Plumeria hasn’t bloomed in a few years, you should prune these plants in the winter.
Cuttings of Plumeria will benefit from the application of rooting hormone as soon as the cuttings have been taken, but they should not be fed with anything other than water until the roots have been established. It is best to wait two weeks after transplanting Plumeria cuttings in the soil before fertilizing them.
It is best to avoid fertilizing Plumeria in dry soil for two reasons,
You run the danger of wasting your feed since dry soil does not retain water. If the soil is dry, then the plant’s roots will absorb nutrients more quickly since they will be parched. However, this might be harmful to the plant.
Using a phosphorus-rich fertilizer can help Plumeria develop stronger buds that will stay on the plant for a longer time if treated regularly throughout the year. You should stop watering only when the Plumeria begins to set its leaves in the autumn. During the winter, Plumeria should get no nutrients at all.
Your Plumeria needs phosphorus-rich organic liquid fertilizers once the blooms have faded and the plant has gone dormant, but keeping proper drainage will help you keep a consistent feeding schedule for your tropical plants. Rock phosphate, which Mother Nature has generously supplied for us to use without cost, is one of the best fertilizers for plumerias that can be purchased.
In order to appreciate these blooms that Plumeria produce, it is essential that you provide them with regular feedings, use high-quality potting mix and fertilizer, and ensure that they get enough water.
