Plumeria ~ A Beautiful Plant to Add in Your Garden

Commonly called Frangipani, plumeria is best known as the flowers in Hawaiian leis. Plumeria flowers are fragrant and waxy. Their leaves are green, long and leathery. You can grow them as small trees, shrubs, or houseplants.

Growing in a container is ideal and makes it easy to move indoors in cold weather. For optimum flowering, plumeria plants should have a full sun, all day. However, with a half-day of direct sun, they will still produce vibrant blooms.

We explain what it takes to grow plumerias and provide a step-by-step guide on how to care for them.

Plumeria

Plumeria is native to Central America, Venezuela, and Mexico. It’s a member of the Apocynanceae (dogbane) family and is related to periwinkle and oleander.

It grows best in USDA hardiness zones 9 – 12 though you can grow it in other zones with enough sun and proper care. Frost is the biggest concern with growing plumeria.

Whether you grow a plumeria tree or a plumeria plant, they both result in highly fragrant flowers. The USDA’s Forest Service considers all parts of plumeria to be toxic. 

You can grow these plants in the form of a bush or an ornamental tree. Of the many species and varieties, most are deciduous though some are evergreen.

How to Grow Plumeria

When it comes to learning how to grow frangipani plants, there are important requirements that you need to meet and keep in mind, such as:

  • Climate and Temperature

If you live in a colder region, you’ll want to grow your frangipani plant in a container. If you plant them directly in the ground, you can dig them up and pot them in the fall. When winter comes, you can continue growing them indoors. 

If you live in an area with moderate winters, in growing zone 9 or higher, you can keep plumerias outdoors in the winter. Pay close attention to frost warnings. When necessary cover them with frost cloth, or bring them inside for the night.

  • Soil

One thing that you need to be aware of is that plumeria can thrive in soil with slightly acidic pH. Use a fertilizer high in phosphorus. Do not use fertilizers that are high in nitrogen as this can result in few blooms. Fertilize plumerias every other week during the summer until the end of summer so new growth has time to harden off before the winter. 

When planting them in a container, you need a coarse-textured potting mix that has the ability to drain water very well.

Consider using either perlite, cactus mix, or even good old fashioned sand as one of your choices. The mix will be enough to keep the plumerias well-hydrated and fed as you care for them in the winter and a controlled environment.

  • Sunlight

The Hawaiian leis plant also requires enough sunlight. These plants should have at least six hours of sunshine to thrive. The more direct sun, the better.

Planting plumeria in containers enables you to move them in areas with full sun. Also, remember that the amount of sun varies by season. As such, plan to move it as needed. 

How to Propagate Plumeria

Before planting plumeria cuttings, which we explain below, you’ll need to propagate them. Planting them is fairly easy, but it’s important to follow the process.

You’ll want to propagate your plumeria cuttings a week before you put them in the soil. The cuttings also need to be hardened. Below are the two simple steps on how to propagate plumeria.

Get the Cuttings

To acquire cuttings, you can either take them from an existing plumeria plant or cut a deep notch in an area where you plan to make your initial cuts. Cuttings should measure between 12 and 18 inches long.

Allow Them to Harden

Once cut, you’ll want to give them a week to harden. The reason is you want to lessen the incidents of infection and promote root growth. Alternatively, you can store the frangipani cuttings in a place with plenty of shade and air circulation.

Keep them there for an entire week and remove them when the time comes to plant. During this time, you’ll want to watch for the cut ends to ensure they are hardening.

If there are soft ends, you’ll want to make the necessary cuts until you see white wood. After you’ve made the cuts, reset the time clock for a week. Keep monitoring them as you normally do.

The sooner the plumeria cuttings harden, the better. While a week is a typical wait time, it could take close to a month or more for them to harden, depending on the cultivar.

How to Plant Plumeria Cuttings

Once you’ve propagated the cuttings and have them go through the hardening process, it’s time to plant them. Here’s what you’ll need for this process and what you should expect beyond that:

Prepare Soil

Mix two-thirds of perlite and one-third potting soil. Make sure you have a container large enough to hold it. Alternatively, if you live in a warmer climate, consider the idea of planting plumeria directly into the ground.

Dip and Sink the Cutting

To make roots grow faster, use a rooting hormone. Dip the cut end and sink it into the potting mix. You’ll want them to sink halfway down. If you need additional support for the cuttings, you can use stakes.

Water

Once planted, water the plumeria cuttings. They should do just fine for a few weeks after. Overwatering them will hinder their growth and can cause them to rot.

Wherever you plant plumeria, in a container or in the ground, be sure they are in an area where you know they’ll get plenty of sunlight. Expect the cuttings to form roots within 60 to 90 days.

Plumeria Care Guide

Even if you know how to plant plumeria cuttings, they will not thrive without proper care. The good thing is caring for plumeria is minimal. Here’s the simplest way to care for plumerias:

Water Them Regularly

As mentioned, watering the Hawaiian leis immediately after planting is a must. After the initial watering, you want to make sure you water it every two to three weeks. It’s best to let them dry out between deep waterings.

Keep in mind, the plumeria plant will dry faster if planted in containers. If that’s the case, adhere to the “every two weeks” rule. Water deeply, and then let it dry. Otherwise, if you planted it in the ground, three weeks should be good enough.

Taper off watering into fall. Stop watering completely in winter when plumeria is dormant.

Apply Fertilizer

If you want to promote your Hawaiian leis plants’ best possible growth, you’ll need a fertilizer high in phosphorus. You should begin to fertilize them at the first sign of growth.

  • Fertilizer Type

There are plenty of time-release fertilizers that you can use to release nutrients over the course of a six- to nine-month period. If you use a time-release fertilizer, you can apply it once or twice a year, depending on the timing.

Otherwise, you can use any kind of fertilizer compatible with plumeria. While finding a fertilizer, you’ll want to keep away from those with high nitrogen content. It will make the Hawaiian leis weaker when fully grown. They won’t bloom as well.

Be sure to stop adding potash to the soil when plumeria buds appear. A good fertilizer combination to keep in mind is 10-30-10. Normally, fertilizers with these numbers will contain a high amount of phosphorus, but lesser amounts of nitrogen.

  • Application Frequency

Apply fertilizer every two to three weeks beginning in the spring and continue up until September at the latest. You must stop fertilizing at least 45 days before the dormant period.

Re-Plant and/or Store Them During Colder or Winter Months

Hawaiian leis plants will not survive in winter conditions. On nights when frost is imminent, it will threaten their chances of survival greatly. Have a plan for the winter before you plant plumeria bushes.

If you live in a frost-prone climate, even in planting zones 9 and 10 can experience freezing temperatures, you’ll need a plan to protect the plumeria trees. You have a few options.

  • If planted in the ground

Cover the frangipani bushes to protect them from the frost, or dig them up and pot them to remove indoors. In some parts of the country, the weather could get cooler by the end of August or early September.

Since plumerias are dormant in the winter, you don’t have to water them nor provide them with sunlight. As for where you should store plumeria plants, you have plenty of options.

You can use your greenhouse, garage, or a section of your basement since these places could provide the plants with sufficient conditions. So long as the storage temperatures are 50 degrees or above, they should be fine.

  • If planted plumeria in a container outdoors

Plan to move the existing containers inside. Overwinter potted plumeria indoors. Be sure to move plumeria indoors when temperatures will be below 40 degrees F.

  • If planted in a pot indoors

Keep your frangipani plant in it’s container indoors year round and treat it as a houseplant. You can grow plumeria plants indoors all year.

Insecticide

The best time to check for insects is before re-planting the plant into the ground around springtime. Regarding insects to watch out for, plumeria can attract scale and nematodes.

Spray the plumeria bushes and trees in the spring. Continue to inspect them regularly. Refrain from spraying insecticide if they are in direct sunlight or showing signs of dehydration.

Use year-round spray oil since it will work around the clock to kill insects and eggs. Avoid using products with synthetic chemicals since they may harm your plants. Apply as needed or periodically as a precautionary measure to eliminate the eggs.

Strengthen the Roots

At the first sign when your Hawaiian leis plants are “waking up” from dormancy, it would be a good time to give them a boost (weather permitting).

You’ll want to soak the plumeria roots in a container of water mixed with a root activator and bio stimulate. It will strengthen the roots, so they are well-fed while in the ground.
