The Plumeria genus is a member of the dogbane household and is native to tropical America. From Florida to Brazil and the Caribbean Islands, these engaging small timber depart an enduring impression on the summer time panorama.
Over time, Plumeria timber have been naturalized in a lot of Asia, together with the Pacific Islands. With a whole bunch of sorts unfold over 12 species, every selection has a singular and delightful colour mixture and a perfume all its personal.
They’ve engaging succulent branches that assist sprays of enormous, engaging depart and bouquets of fragrant flowers on the finish of every department.
Their progress behavior varies between species, with most timber rising between 1’-2’ per yr. They’re very receptive to pruning, so that they make great container vegetation in climates the place they should be introduced indoors for the winter.
Plumerias are deciduous small timber or shrubs. Throughout the plant’s dormant interval, which coincides with the drought season in its native panorama, Plumeria drops its leaves. It wants little to no care in any respect throughout dormancy till the plant begins one other progress cycle.
The dormant interval coincides with winter within the Northern Hemisphere, making this an incredible indoor/out of doors plant in colder climates. The tree might be moved indoors within the chilly climate and wishes minimal tending till the climate warms.
Plumerias start to develop in spring, branching from the information the place the leaves and flowers have fallen. Each 1-2 years, these vegetation will develop new branches, and it’s on the ideas of those branches that they are going to develop flowers. Plumeria at all times blooms on the most recent wooden and sometimes flowers earlier than new leaves develop.
The sleek, gray trunks of those vegetation are skinny and versatile, making them get up nicely to robust winds. As soon as mature, they’re very arduous and sturdy.
Their most important sensitivity is to chilly and moist climate. This will doubtlessly harm the plant’s root system, which is prone to fungal root rots that thrive in cool, damp circumstances.
Plumeria leaves are lengthy and ovate with typically rounded however often barely pointed ideas. They’re closely veined and have a shiny, waxy heaviness.
These leaves are good inexperienced and develop in clusters that type on the ends of the most recent branches. The expansion behavior provides this tropical plant a palm-like look.
Plumerias might be pruned into completely different shapes, which additionally determines the density of their foliage. It’s attainable to have a tree that has very dense foliage or one which has extra staggered branches.
Plumeria’s flowers are the true star of this present. The blooms seem in a cluster on the ideas of every of the most recent branches, typically blooming earlier than any leaves seem. Plumerias usually bloom from late spring till early fall. Nevertheless, in very heat climates, they’ve been identified to bloom year-round.

Whereas there’s not one constant scent that may be assigned to those flowers, they’re practically all aromatic.
These beautiful timber have been naturalized in lots of tropical landscapes and are highly regarded in Hawaii, the place they’re the signature flower from which leis are constructed. The attractive Calcutta Star selection is claimed to be probably the most aromatic of all of the Plumerias and has a robust and spicy scent.
Propagating Plumerias is an attention-grabbing matter. The method of propagation is nearly too straightforward to be true. Whereas they are often grown from seed, propagation from cuttings is mostly very profitable, so there’s little motive to propagate in some other method except you are feeling so inclined.
Had I not witnessed firsthand the simplicity of propagating Plumerias from cuttings, I’d hesitate to say this. Whereas I’m going to share some ideas for making certain the success of your endeavor, I’ve actually snapped a department off of one in all these timber, popped it right into a pot filled with soil, and ended up with a full-grown tree in a matter of three years.
In brief, propagating Plumerias from cuttings is nearly foolproof, however listed here are a number of recommendations which will assist give your Plumeria a head begin.
- Select a sturdy department from the mother or father tree. A department of about 1’-2’ is good and might be eliminated with out corrupting the form of the tree.
- Disinfect a pointy knife or software for slicing and sever the department from the mother or father plant. Attempt to lower it flush with the supporting department.
- Apply powdered sulfur to the cuts to forestall fungal or bacterial invaders.
- Take away all flowers and foliage besides for 2 leaves and permit the tip of the department two weeks to callus over.
- You may wrap the tip in plastic wrap or depart it uncovered in a damp local weather.
- As soon as the tip has callused, fill a pot with a rough mixture of potting soil and sand or pumice.
- The potting medium must have good drainage, as Plumeria is prone to root rot.
- Place the department lower aspect down into the soil about 2” deep and water in.
- Chorus from watering once more till the department sprouts new leaves.
- Transfer the pot to your required location and permit the plant to acclimate.
- As soon as the slicing is firmly rooted, you may transplant it into the bottom or a bigger pot and revel in your new plant.
Rising Plumeria from seeds isn’t far more sophisticated than from cuttings. The seeds needs to be soaked in water in a single day and planted in a cactus combine or different coarse combined soil, fats finish down.
Give your seeds a little bit of water, and they need to begin exhibiting up inside 1-3 weeks. That’s it! Then, merely let your plant develop till it’s about 1’ tall and transplant it to its closing vacation spot.
I need to embody a be aware on grafting due to some thrilling practices that produce great and distinctive timber.
As a result of every tree has its personal flowers distinctive to the variability, it’s attainable to graft branches from completely different varieties onto the identical rootstock to provide a tree with different-colored flowers on completely different branches. The impact might be fairly breathtaking.
Rising Plumeria is simple each in containers and within the floor in case your local weather permits it. They’ve related must succulent vegetation and tolerate a spread of soil and lightweight circumstances.
Plumerias make great decorative timber that add colour and perfume to the setting through which they’re grown.
Planting Depth and Potting Wants
If you’re planting within the floor, it has very modest wants by way of soil. For those who stay in a local weather the place Plumeria can develop outdoor year-round, likelihood is good that your soil has a good quantity of sand in it, which makes for good drainage.
In case your soil may be very dense, clay-heavy, or compacted, it’s possible you’ll need to amend the soil with some coarse sand.
Plumeria timber want barely acidic soil. A pH of 6.5 or decrease will make this plant blissful as it’s going to be sure that the vitamins within the soil can be found for the Plumeria’s use. Ensure to decide on a spot with good drainage. Soggy Plumeria roots can result in root rot which is often deadly to the plant.
Dig a gap as deep and large as the basis ball, situate your Plumeria within the gap, and fill in any remaining area with the soil you beforehand eliminated. Water in in order that the soil is moist however not overly moist.
For those who stay in a local weather the place the temperature falls to freezing, Plumerias will should be introduced inside within the winter, and they also will should be grown in a container.
As a normal rule, select a pot that’s one gallon per foot of tree peak. It will give your tree some room to develop with out being repotted yearly. Use a cactus potting combine or a combination of soil with coarser components added, and ensure to make use of a container with good drainage.
Plumerias are light-loving vegetation. They like to obtain 6-8 hours of direct solar. It’s preferable that these hours happen within the morning and that the tree receives some respite from the solar in the course of the hottest hours of the day.
When grown in hotter climates, Plumeria can tolerate being planted partly shade, notably within the afternoon. Plumeria ought to get a minimum of 6 hours of direct solar day by day.
When grown indoors, these vegetation should be in shiny gentle for a lot of the day, as they won’t flower with out sufficient daylight. A south-facing window is a superb spot for a Plumeria within the northern hemisphere!
A newly planted Plumeria needs to be watered very sparingly. The roots needs to be allowed to dry out between waterings, which is able to encourage root improvement as they’ll begin looking for out their very own water supply additional down. Plumeria roots nonetheless do want entry to oxygen to develop, and being in soil that’s compacted or waterlogged will complicate this.
As soon as leaves start to develop, watering might be elevated to a few times weekly for an out of doors plant. These vegetation needs to be watered deeply in order that they’ll retain the water to retailer for drier climate.
When Plumerias lose their foliage and go dormant in winter, you may stop watering altogether. Plumerias don’t want further water whereas dormant.
Mature Plumerias are higher off being underwatered than overwatered. Of their native setting, these vegetation are accustomed to durations of wet climate and durations of drought. In consequence, they can retailer water and might tolerate a little bit of neglect.
When planted outdoor, they are going to be fantastic with out watering throughout instances of normal rainfall.
In summer time, if there was a scarcity of rain, and your Plumeria is wanting wilted or the leaves are turning brown on the edges, it most likely must be watered. The trunk and branches of an underwatered Plumeria will lack rigidity. This will result in the looks of the entire plant drooping.
Local weather and Temperature
The best temperature vary for a Plumeria is 65°-80°F. Nevertheless, they’ll tolerate plenty of warmth, and temperatures right down to 40°F is not going to do any actual harm.
Temporary temperature dips into the 30s are typically not dangerous, however Plumerias can not tolerate extended temperatures near freezing.
Plumeria blooms are signaled by a rise in water, daylight, and warming temperatures in spring. They’re tropical vegetation, so that they like warmth and daylight, and so long as they get common rainfall, they are going to look their greatest in the course of the warmest months.
Plumerias do greatest in a minimum of 50% humidity throughout progress durations. In case your Plumeria is stored indoors, utilizing a humidifier or misting it frequently will hold it blissful.
Watch out to solely mist the foliage and never the flowers. Misting the flowers will make them extra weak to the fungus Botrytis.
There are differing factors of view on fertilizing Plumerias, various from as soon as per week to solely within the fall in preparation for dormancy. Someplace within the center might be the very best observe.
I like to recommend fertilizing as soon as monthly to 6 weeks from spring by way of fall with a bloom-boosting fertilizer. Including an Epsom salt answer as soon as monthly, on a special week out of your fertilizer, will assist reinforce cell partitions, making the plant stronger in addition to rising the variety of blooms produced.
Pruning and Upkeep
Plumerias are very resilient and might tolerate arduous pruning higher than most timber. If, for some motive, you need to begin over together with your Plumeria, you may prune all of it the best way again to about 1’ tall, and it is going to be simply fantastic.
Causes for doing this might embody desirous to reshape the tree totally or thicken the limbs up if too many have been eliminated.
Generally, when doing routine pruning to take care of the scale and form of the tree, pruning is greatest accomplished in winter or very early spring. It will keep away from interrupting the blooming cycle. Pruning additionally encourages new progress, which is fascinating in the course of the rising interval, however not a lot when the tree is dormant.
Utilizing sterilized instruments, trim off any overgrown branches, leaving about 1” of the department on the base to encourage extra branching. For those who intend to propagate your cuttings, lower them at an angle so that there’s loads of area for roots to develop. Slicing at an angle additionally helps to forestall the pooling of water and wards off tip rot.
Lifeless and diseased branches might be trimmed off at any time of yr. It’s best to take away broken branches as quickly as you discover them, permitting the plant to redirect its vitality to new progress and eliminating the potential of any illnesses current to unfold.
All elements of the Plumeria plant are poisonous, together with the sap. This sap, which the tree will excrete when it’s lower, may cause irritation to the pores and skin.
Because of this, it’s best to put on gloves and lengthy sleeves when pruning this plant. The plant may be very bitter tasting and usually unappealing to animals, so it’s not as harmful as different poisonous vegetation.
