Key Takeaways

  • Plumeria grows well in the spring and summer months. Hence, for healthy and new growth of the plant and flowers to bloom, it is important to keep it away from the hardiness zone.

  • For full growth of the plant, you have to make sure to avoid any type of pest infestation, or tip rot, and avoid growing during the dormant period, that is during winters.

  • To encourage plumeria growth during winter, you need to provide the plumeria winter care, like preparing the soil with the best quality potting mix.

  • Along with the potting mix, add peat moss to intensify the acidity and oxygenation.

You know well that plumeria is a tropical plant. The roots of Plumeria are found in central and South America.

Here in this article, you will get to know a detailed account of how to grow plumeria indoors. The necessary elements required for the healthy growth of plumeria indoors are enough sunlight, regular watering, and planting the plant in healthy soil. Apart from that, keeping an eye on the growth of plants by providing them supplements like, potting soil, fertilizers, etc also helps the plants to grow and blossom nicely.

Light and Temperature Requirements of the Plant

Like any other healthily growing plant, the plumeria plant also requires proper light and adequate temperature for growth. We know that plumeria is a summer plant that grows in the early spring season. For a Plant to grow plumeria flowers are very beautiful, so it is important to provide it the bright light and fresh soil for producing fragrant flowers.

Bright Sunlight

Because plumeria is a tropical plant, they do not fare well in cold areas. For some of us, this simply means putting potted plumeria trees in a sunny window, but for others, it can be a little more difficult to meet the lighting needs of the plumeria that are in bloom.

Plumeria really enjoys a position that is bright and sunny and a few meters away from a window that faces south. Your natural inclination when growing potted plumeria flowers is to give them as much light as they can receive, but keep in mind that humidity in hot weather increases with distance from the equator. 

A plumeria can avoid stem rot, avoid root rot, and fend off spider mites with just aeration and warm temps. Any longer than six hours a day in direct sunlight will exacerbate some of these issues with plumeria trees. Ideally, they actually like light that is diffused via other plants, such as hanging tropicals that soak up the strongest heat and let sufficient sunlight through for your frangipani.

For better growth of Plumeria, it is recommended for the plant to have full sun. Full sun is defined as 6–8 hours a day of uninterrupted, direct sunshine. This entails planting indoor plants within a meter of a south-facing window.

Perfect Temperature

Plumeria Indoor

As far as temperature is concerned plumeria plants grow best in USDA zones. Plumeria plants are intolerant to winters or low temperatures. The maximum minimum temperature plumeria plant can bear is about 10 degrees centigrade. If the temperature crosses the limit then the parts exposed to the falling temperature may die.

The best-suited temperature for planting plumeria plants indoors is between 65 degrees to 80 degrees Fahrenheit or 18 to 27 Degree celsius. If in case the temperature falls below 10 ゚C then the plant will go dormant and start to go dormant and start to drop its leaves.

Protecting Plants from Extreme Temperatures

Plumeria requires a lot of care. They need frequent fertilizing as well as strict monitoring to avoid illnesses and pests including blacktip fungus, mealybugs, and spider mites. But during the winter, this can be even more challenging because, when grown outside of their native tropics, they require serious attention to avoid root rot, stem rot, frost damage, and branch dead wood, all of which can either completely kill the small trees or prevent them from flowering regularly the very next year.

It’s essential to winterize plumeria for a strong plant in the spring. Winterizing is the practice of properly preparing your sensitive plants for winter, not merely moving them.

If the temperature falls below 50F, plumerias won’t be able to recover from the harm caused by the frost. They ought to be over 60F, and if possible, even 75F. Overwintering plumerias that are cultivated inside is simple.

Cut back any unhealthy, diseased, or damaged growth, clear the area around the plant’s base of fallen leaves, and suspend watering for a few months. They will become dormant and stop developing as the days get shorter in the winter. In the spring, they will spontaneously start to grow afresh.

Watering and Fertilizing the Plumeria Plants

Taking care of plumeria is neither too easy, nor too difficult. The gardeners need to know the right quantity of water and fertilizers to be provided to the plant outdoors and indoor plants.

The same is the case with fertilizers. When growing plumeria indoors, you need to provide fertilizers to the plant every two-four weeks. good quality fertilizers help to grow plumeria faster.

Mid-fall is the best time to cut back on watering, and after the plants go into dormancy for the winter, fully cease. Once springtime arrives and fresh growth starts to develop, start watering again. A fertilizer with a high phosphate content, such as 10-30-10, will support plumeria flower blossoming. A surplus of nitrogen will only promote rapid leaf growth and minimal blooming.

Watering Schedule for Plumeria Plants

There is no such fixed watering schedule for plumeria plants. What is to be kept while taking care of the plants is to keep a check that whether it has moisture in the soil or not. Never allow the plant to run out of moisture ever.

After it dries out, totally soak the pot until the water flows through the openings at the bottom of the pot.

Best Soil for Plumeria Plants

Growing inside is frequently simpler because you may occasionally swap out the dirt. Like many other plants, plumerias require a lot of drainages. This commonly enters potted plants through the holes drilled at the bottom of the pot. But, putting an additive to the containers as well as the garden might assist lower the possibility of saturated soil from powerful storms.

For a planted Plumeria plant, add a bottom layer of fine tiny pebbles before filling the container with soil. A great, loam with a little acidity tends to be preferable, as this kind is open, well-draining, and has abundant organic matter.

The organic matter doesn’t merely fuel your plant between Plumeria fertilizer treatments. It also stimulates earthworms and other organisms, which help aerate the soil.

Common Issues with Planting Plumeria and Solutions to it

In a dry climate, particularly during the summer season, plumerias are often not afflicted by most fungal infections. Yet, these frequent illnesses can emerge during the milder winter months, particularly if the soil is left wet or your plants are overwatered. Some fungal infections are also possibly contagious in young-rooted cuttings.

Pali Plumies - Common Diseases in Plumeria and Proper Preventative  Treatments


Plumeria is one of several plants that can get rust diseases or rust fungus. Rust is generally somewhat particular about the hosts it may live on. Many rusts include several types of tiny spores.

Such variants allow the fungus to live throughout the year on one parent and for part of it on another, infecting two completely distinct plants.

Plumeria rust is a fungal infection that has become well-known for its noticeable, granular, yellow-orange blemishes on leaves. The presence of yellow, orange or reddish-brown granular abscesses on the foliage, stems, or buds of the diseased plant can always be identified. 

These pustules release spores that are then spread to nearby healthy plants, where they cause new infections, by splattering rain or air currents.


If it has a significant head start, Black Tip Fungus is exceedingly difficult to manage. Black Tip can show up throughout the course of the year, although it often attacks in the early summer and the fall. Black Tip Fungus prefers gloomy, damp, and chilly environments. When the circumstances are ideal, they may almost appear overnight and grow exponentially.

If left unchecked it will destroy the growing tips of established trees, and kill totally a little plumeria. As the weather warms up after Black Tip has destroyed the growing tips on a mature plumeria, Black Tip will disappear. The blackened tips will calluses and separate at that point.

The plumeria will then start to spread out again as if it had been clipped. When a tree grows a lot of new branches, it’s not always terrible, but if it does it frequently, it will be difficult to get your plumerias to blossom.

Solutions to the Issues

1. Search for Longhorn Borer Symptoms

Look for little holes seeping a dark material on the plumeria stems. During winter pruning, remove any branches that are twisted or shriveled by punching these holes at the base.

2. Look for Black Mold

Leaves with white or black dots may have a dual issue. Whiteflies may congregate on the underside of leaves and exude a sticky material, which then promotes the growth of black sooty mold. Both of these issues may be solved with fungicide treatment and insecticidal soap.

3. Check for Cutworms on the Plant.

Slugs and snails prefer to attack one region at a time and leave slime trails behind them, but cutworms will eat any portion of the plumeria plant. Dursban or diazinon applied to the soil will stop cutworms in their tracks. Diatomaceous earth can be used to discourage snails and slugs.

4. Look for Pill Bugs and Aphids.

Keep an eye out for any parts of the plant which appear to be coated with any unusual chemicals. Sticky coatings on plants are sometimes an indication of insect activity. A garden hose spray of water helps flush off aphids.

5. Maintain a Clean Yard

Periodically rake up trash from the tree as appropriate housekeeping procedures aid in the prevention of illnesses and issues.


To conclude the article, it can be said that Plumeria is both an indoor and outdoor plant. All that it needs for proper growth is natural light, adequate drainage, and good quality fast draining soil that is rich in coarse sand.

Also, for the growth of various colorful flowers like white flowers, you should provide adequate fertilizers and maintain well-draining soil.
