This formula does not only target the flower, but it also improves the quality of the soil.

Unlike Miracle-Gro and Dr. Earth, this product has more nitrogen content than phosphorus. We may have suggested that you choose products with more phosphate content, but this does not fall behind its competitors. If you are planning to plant your plumerias outside, this could be the right pick.

Another advantage that you will get from this solution is your plant’s capacity to surpass dry weather. With a weekly application of this fertilizer in the summer season, you can maintain the beauty of your garden.

You do not need to wait for long to see obvious results. After a while, you will observe a few positive changes to your seeds or dying plants.

Keeping Your Plumerias in Check – Buyer’s Guide

You must remember a few things when gardening plumeria. While it is not a high maintenance flower, it deserves to be treated like the rest of your girls. Here are four tips to guide you when growing this flower in your backyard. 

Plumerias Need Enough Sunlight

There is a reason why plumeria is a tropical plant. It needs enough sunlight so that it can photosynthesize and reproduce properly. This flower-bearing plant needs at least five hours of direct heat from the sun. However, you should avoid exposing it to heat for longer hours because it will dry your flowers. Moderation is the key so that your flowers will bloom at its optimal capacity. 

Potting Plumeria Is Essential

It would be best to put your plumeria in a pot. Please make sure that the size is enough for it to grow its roots and absorb water. You must also ensure that the pot has well-drained soil. Keeping it wet all the time may cause moisture and produce toxins that are harmful to your plumeria. Overhydrating your flowers will kill it in no time. 

Use Fertilizers With Enough Phosphate Content

If you read the earlier parts of this article well, you may have learned that phosphorus is the key element for flowers to bloom with freshness and vibrancy. That is why you have to check the NPK content of your plant food. According to experts, water-soluble fertilizers should have at least 50g of phosphorus, and granular fertilizers should have at least 20g. Supplementing your soil with inoculants that facilitate phosphorus production may also be helpful. 

Weather Affects the Amount of Water Needed

You have to give more water to your plumeria during sunny seasons. It is the time when these flowers start budding. Thus, hydrating it will affect its growth rate. However, please be careful not to water it at an enormous amount. You can skip watering or pour a little amount for it to get by during the cold weather. 


Conclusion

As we end this article, please do not forget what you have learned about taking care of your plumerias. Fertilizers come in different ingredients, and what matters is that you got the right amount of phosphate and measurement in your potted plants. As spring and summer are coming, it is time for you to begin seeding them so that they will fully bloom in the tropical seasons. 

We highly suggest that you try to use Miracle-Gro’s product when feeding your plants. It does not need a lot of maintenance, and the price is reasonable enough for its effectiveness. You can also check other brands if you are looking for other elements not found in our recommended item.

Growing flowers in your garden is a fulfilling activity once you see them bloom. It may be challenging to maintain, but products in the market would help you do the task correctly. With proper research, you shall be equipped with enough knowledge on how to improve your gardening skills. 


FAQs (Frequently Asked Questions)

What is NPK?

There are three essential elements that plants need when you grow them. NPK stands for nitrogen, phosphorus, and potassium. NPK’s amount may vary from one fertilizer to another. Since we are dealing with plumerias here, a tropical plant, it is best to ensure that your NPK has a higher phosphorus content. That is the middle number in this formula. If the solution has more nitrogen, you can expect to have taller plants with lesser bloom.

Can you grow plumeria indoors?

Yes, you can grow plumeria indoors. However, it would help if you kept in mind that this plant needs enough sunlight to survive. Even if you are only living in a dorm, find a spot where it can absorb enough sun for at least five hours a day. After that, you can keep it in your room and feed it with some fertilizers. It would be best if you do not forget to water it as well. Sunlight, water, and air are the main elements that keep a tropical plant alive. 

What are the nutrients needed by a plumeria plant?

There are sixteen elements that a plumeria needs to survive. They are classified into two major groups, which are the mineral and non-mineral elements. Hydrogen, Oxygen, and Carbon are examples of the latter. They are found in the water content that you give to your plants. The other 13 are further divided into micro and macronutrients, which are found in the soil. They include the NPK, Calcium, Magnesium, Manganese, and Zinc, among others. With the right fertilizer, you will get all these elements to help the growth of your plumeria.
