Proper care entails adequate sun and appropriate watering

Raise Healthy Plumerias

Plumeria is a beautiful tropical flowering plant that has a wonderful fragrance.

Frangipani trees grow throughout warm exotic spots around the world. The traditional Hawaiian lei is made from its flowers. Also known botanically as Frangipani, you may grow them in your U.S. landscape if conditions are warm enough.

Some grow them in containers and bring them indoors for the winter so they can enjoy the beautiful, fragrant blooms outside from spring through fall.

This plant makes a wonderful addition to any home and does not necessarily need to be grown in a tropical environment as long as you provide your plumeria the right care and fertilization. 

Nutrients Requirements

Frangipani plants require a lot of phosphorus to promote blooms over foliage growth. Fertilizers that have too much nitrogen, it will result in a lot of foliage, but will not result in adequate flowering – this is why we recommend an N-P-K ratio of at least 1-3-1.

Oftentimes, they may benefit from even more phosphorus such as a 1-4-1, 1-5-1, or even 1-6-1.

Acidic Soil that Drains Well

Plumeria do not need to be grown in the tropics, but they do need the correct type of environment.

If possible, have a well-draining soil that is slightly acidic. This way, you can mimic its natural environment as closely as possible. If you are growing your in a pot, make sure that the pot has draining holes so that the roots are not sitting in excess water. Remember, while water is necessary to maintain its homeostasis, too much water can be just as bad for a plant as too little water. Excessive water and watering is oftentimes the reason that owner’s have difficulty keeping their plumerias alive.

Ideal fertilization will have high phosphorus content

Sun Exposure

As you might imagine, plumeria plants require a decent amount of sun exposure. I recommend at least 6 hours of full sun exposure per day. These tropical plants do not tolerate cold very well. For this reason, putting your plant in an area with full sun or in a south-facing window is ideal to allow optimal growth and to promote blooms.

Bottom Line

Again, I recommend buying the Grow More Hawaiian Bud and Bloom. You will get healthier and bigger blooms with optimal nutrients. If you buy any old fertilizer at your local gardening store, you may not realize that your plumerias are not getting the ideal nutrients until it is too late.  You cannot go wrong with any of the products above.
