Do you have a hoya plant? If so, then this blog post is for you. We will discuss how to care for your hoya plant and the best practices to keep it healthy and happy. Hoya plants are great because they don’t require too much attention, but that doesn’t mean that they can fend for themselves! Your plants need love, just like any other living thing in your home – and we’re here to give them some of our time!

Hoya Plants

Hoya Origin

Hoya plants, also known as Wax Plant have been around for centuries. The plant originally comes from Asia but it can be found in most of the world today. Hoya is a broadleaf evergreen shrub that grows up to about 15 feet tall and wide with colorful leaves on long stems which grow straight out perpendicular to the ground or curve gently downward as they mature.

These beautiful flowers are grown primarily indoors since many species do not tolerate cold temperatures well outside their native environment (usually tropical) and need bright indirect light year-round. This means that you must provide artificial light sources during the winter months when natural sunlight is lacking or filtered through clouds or windows.

Number of Species

Hoya plant care is a bit more complicated than other house plants because there are over 125 species of Hoyas. The number one rule for all Hoya Plant Care is to avoid overwatering your hoya and always allow the soil to dry out before watering again. This will prevent root rot, which can kill your Hoya quickly.

Hoya Classification

Hoya plants are members of the four-o’clock family and cacti. Like many other succulents, Hoyas need a lot of sunlight in order to survive. They also like airflow so they do well near an open window or door.


The flowering varieties of the hoyas need bright light with some direct sun, but not too much or they may get scorched. The non-flowering ones need filtered sunlight only; an east-facing window is perfect for them.

They can also grow under fluorescent lights, as long as these are close enough so that their leaves do not burn. A little warmth might help: artificial heating pads will allow you to place your plants anywhere and maintain a stable temperature all year round – just make sure there’s no chance of water leaking onto electrical outlets!

Watering Your Hoya

When it comes to watering your hoya, there are a few things you need to know about how often and when. The basics of this plant are that they love water and humidity – which means rain or high misting will be the perfect amount for them depending on where you live!

If these aren’t possible in your house then try using an automatic mister set up near the plant with plenty of room around it so it doesn’t get too wet. It’s best not to have any plants directly under a window as well because direct sunlight can dry out roots from overexposure.

Try setting up some lights nearby instead so those won’t be affected by direct light either during the daytime hours. Lastly, don’t forget to water your hoya weekly, or if it’s really dry outside let the soil get almost bone-dry before watering again.

When you’re transplanting a hoya plant from outdoors to indoors, make sure that the temperatures in both places are similar! If they differ too much there can be problems with humidity and temperature so try adjusting them both to be similar.

Potting Your Hoya

You will need a pot that is at least 12 inches deep. The roots of the plant are very invasive, so be sure to use a container with enough depth to allow for its growth. Use an appropriate soil mix or create your own by combining equal parts peat moss and well-mixed compost (a ratio of one part each).

Fill the pot with your soil mixture, and then place the plant in it. Position the hoya so that its crown is just below the surface of the mix. Then lightly press dirt around it to hold it securely.

The best time for repotting a Hoya Plant is during warm months when they’re actively growing. Once you’ve repotted your Hoya Plant, water it and place the plant where it will receive full sunlight.

If you have a pot with drainage holes in the bottom, be sure to use this type of container for repotting during dry months to avoid overwatering.

While we don’t recommend keeping an ornamental hoya inside, if your home is too cold for a Hoya Plant, try placing it near an east-facing window. If you’re unable to place the plant in direct sunlight or outside, use fluorescent lighting and feed weekly with a dilute general-purpose fertilizer diluted by half (one-quarter strength).


The soil that your Hoya plant is in needs to be a light, well-draining potting mix. If the soil holds too much moisture and water doesn’t drain through it easily, then you have chosen the wrong type of potting mix. You can buy commercial potting mixes at garden centers or nurseries, or simply make your own. Mix one part of sterilized organic potting soil, one part of builder’s sand, and two parts perlite to create your ideal Hoya plant growing media.


A good rule of thumb is to fertilize your hoya at least once a month. The easiest way to do this is by using the liquid fertilizer that comes with it when you purchase it from a nursery, but you can also use time-release pellets or an all-purpose plant food (that says specifically on the label “for potted plants”) which contains nitrogen, phosphorus, and potassium.

You should fertilize your hoya at least once a month with a liquid fertilizer that comes packaged with it when you buy it from the nursery (or time-release pellets or all-purpose plant food). The best way to do this is by following these steps:

Let’s go over how to fertilize your hoya:

  • Pour water into the pot up to about one inch from the top.
  • Use a liquid plant food at least once per month, but do not overfeed it! If you are using fertilizer granules or pellets that require watering in with soil, use them every two months instead of monthly.
  • Fill the pot about halfway with water.
  • Add fertilizer to the top of the soil, following package instructions for how much is needed (usually once every two months). Allow it to soak in and then add more water if necessary so that you’ve reached a total amount of one inch from the top.
  • Put your pot in a sunny spot with good air circulation and enjoy!


A Hoya doesn’t require a lot of humidity, but they do need to be watered with room-temperature water. If you want to increase the humidity around your plant, misting it regularly is an easy way to achieve this goal. Be careful not to overwater them though! They like moist air and soil, but too much water can make them die.

Another way to increase humidity is by placing your Hoya near a steamy bathroom or kitchen window provided the plant has enough light and ventilation in that area of the house.


Your Hoya Plant thrives with a temperature between 18-35 degrees Celsius (around 65-95F) and humidity at around 60%. This is roughly equivalent to the temperatures that you’ll find in most of North America, Europe, China, Japan, and so on.

The higher end of this range is generally what your plant will thrive in. If you’re worried about your plant wilting, ensure that it is getting plenty of water and shade when the sun gets too strong for a while.


To keep your plant healthy, you need to prune it. When the plant is young and has not been flowering for a year or two, cut off all of its branches. Do this every one to three years (depending on how fast they grow). You should do this so that the plant will have more energy in producing blooms.

You can also prune mature plants if they have grown too large for their containers. Just be sure to cut off only the branches that are touching the ground or hanging over other plants, as these will not flower again.


Hoya plants are propagated by layering stem cuttings. In order to layer a cutting, first find an area on the mother plant that has roots growing down from it into the soil and trim off any leaves up high so they don’t get in the way of burying this new cutting.

You want as much healthy root on the cutting as possible to ensure a good start. Next, cut off at least three nodes from this area of healthy roots and trim them back about an inch or two all around.

Now you have your layered stem cutting with plenty of root material below is ready to be buried in the soil. Make sure that there’s enough room for the cutting in the pot or container you’re going to be planting it into. You can usually bury cuttings about two inches deep, but measure your height and go with whatever is most appropriate for your plant.

Once it has been buried up to its final depth, water thoroughly until soil settles around the new stem at its proper level. Make sure not to cover more than three nodes on this stem.

You want that part of the plant healthy so that if a secondary branch does grow later, there will still be plenty of leaves high enough above ground where they won’t get damaged by sun or rain damage.

Situate the potted cutting as close as possible to an area of sunlight (most Hoyas thrive best when they receive at least eight hours of direct sunlight a day), and be sure that the pot is able to drain well.

To avoid root rot, it’s important to water your new Hoya cutting regularly but sparingly. Every five days or so should suffice, just enough for the soil to become moist again without being saturated with too much moisture which can lead to mold growth and other illnesses in plants like these.

Remember also that Hoyas are sensitive creatures who thrive on consistency when you water them: watering once every five days will provide them with a sense of stability they need if they are going to survive their first weeks as houseplants! You may find yourself wanting more frequent watering than this, however, depending on how warm your home is and how bright your bathroom lights are.

Pests and Disease

Pests and disease can be a problem with Hoyas because the plants are often grown in such close proximity to one another. It is important to check new imports for signs of pest infestation or diseases before they’re planted among established Hoya collections. The following pests have been reported:

There are no reports of fungal, bacterial, viral, or parasitic infections affecting Hoya as far as we know. Allergic reactions from contact dermatitis may occur if you come into contact with the sap while pruning; this rash usually resolves on its own after exposure ceases but it’s best to wear gloves when handling any part of the plant (including leaves) since your skin will become more sensitive over time.

We do not recommend using Hoya plants directly on bare skin or in any area where exposure to the sap will occur. We recommend wearing gloves when handling Hoya leaves since contact with the plant can cause a heightened sensitivity to sap over time.

Hoyas are toxic and should not be ingested by humans; we do not sell them for this purpose nor provide information about how to use them as an ingredient for foods or drinks that people consume.

In addition, because Hoyas have historically been used as a folk remedy and because they produce white latex-like sap containing cardiac glycosides, it is important to consult your doctor before using these plants if you’re pregnant (or trying), nursing someone who’s pregnant, taking prescription medications of any kind including herbal remedies, or are suffering from heart disease.

Troubleshooting Your Hoya Plant

One of the most common problems gardeners have is that their hoya plant has stopped blooming. We’ll look at some reasons why this may be. If a plant doesn’t get enough light, it can cause many issues within the plant’s physiology and growth in general.

The leaves will grow large but appear yellowed or plucked off from stress caused by too much shade on them and not enough sun to produce food for themselves through photosynthesis. Hoya plants like bright indirect sunlight which provides warmth without scorching rays difficult to control with other types of window treatments such as blinds or curtains.

If your hoya is receiving insufficient amounts of light then you should move the pot closer towards an eastern window if possible (morning sun) or a western window (afternoon sun).

Why Are The Leaves Turning Brown?

If your Hoya Plant’s leaves are becoming brown, it is most likely due to overwatering or too much water sitting on the surface of the soil. To remedy this problem you may need to repot your plant into a larger pot with fresh potting mix and allow more air circulation around the roots by pruning some of the root tips.

Why Are The Leaves Turning Yellow and Drooping?

If your Hoya Plant is drooping and its leaves are turning yellow, it may be due to a lack of water or improper watering practices. You might need to stop fertilizing so as not potentially damage the roots with too much nitrogen and start using a fertilizer that specializes in potassium-rich nutrients instead.

Growth Habit

Hoya plants are typically grown as a vine that clings to trees or other structures. The vines can grow up to six feet long and needs lots of space in order for the plant to thrive properly. Hoya plants usually have large clusters of flowers all at once, but they are not always flowering because it is an evergreen plant.

Hoya leaves

The Leaves are glossy, green, and usually heart-shaped. They can grow up to six inches long with some reaching eight inches in length. The hoya plant is a slow-growing flowering vine that thrives indoors as well as outdoors.

Hoya stems

The stems on a Hoya are typically long and thin. They need to be kept moist but not wet for the best growing conditions. Holding water in the hoya pot is ideal because it will ensure that there are no dry spots on the soil, which can lead to root rot or other issues with your plant’s health.


Blooming Hoya plants generally require the following conditions:

  • Sunlight, but not direct sunlight. They can also grow in low-light situations provided they are given a window of at least six hours each day.
  • Temperature range between 65 and 90 degrees Fahrenheit (18 to 32 degrees Celsius).
  • Humidity around 50% or higher.
  • Plenty of water, but not enough to form pools on the potting soil’s surface. However, do be careful when watering in that too much water can lead to root rot which will kill your plant. It is recommended to read the care instructions for your specific type of Hoya Plant, as they differ in care requirements.

Types of Hoyas

Hoya Carnosa

The Hoya Carnosa is a tropical plant originating from the Philippines. It has large leaves and blooms with star-shaped flowers in reds or purples surrounded by yellow petals. The flowers are quite fragrant, like honeysuckle or lychee fruit.

Hoya Carnosa

This type of hoya will grow well indoors year-round; they have the advantage of not requiring a lot of sunlight, and they’re also fairly easy to care for. Unlike other types of hoya plants, this one should be watered more often than every couple of weeks; by watering regularly with lukewarm water you’ll encourage good blooming as well as healthy foliage growth.

Hoya Pubicalyx

There are many different types of Hoya Plants, but the most common is called the “Hoya Pubicalyx” or “Tropical Wax Plant.” This type of hoyas originates in India and Sri Lanka.

In its natural habitat, it grows on tree branches near riversides or on rocks or cliffs.

Hoya Sexangularis

In the wild, Hoya Sexangularis can be found on trees in the forests of Malaysia. In addition to being a climbing plant, it is also known as a “leafless flower” because its flowers are not visible until after pollination and fruit production.

Hoya Sexangularis

It’s most famously recognized for its ornate leaves that have unique patterns like no other plant.

Hoya Curtisii

The Hoya Curtisii is a species of flowering plants in the family Apocynaceae. This vining plant grows well in USDA zones nine and ten. The most distinguishing feature for this type of hoya is its thick, leathery leaves that range from dark green to deep purple on the vine’s aged stems.

Hoya Curtisii

It does not produce any flowers or fruit but produces an extensive root system that can grow up to two meters long.

Hoya Krimson Princess

Hoya Krimson Princess care is a beautiful and easy-to-care-for houseplant. The genus of Hoya is ”Apocynaceae” with the species name being ”Krimson Princess.”

Hoya Krimson Princess

They are found in India, Southeast Asia, Queensland Australia as well as parts of China.


Hoyas require very little care in order to thrive as houseplants! They need only be watered an average of once every five days or so (but feel free to water them more frequently if you want!). The pot needs to drain well when watering and they also do best with some indirect light on a day-to-day basis. They should never have direct sunlight because it might burn their sensitive leaves. Keep these tips in mind for your new Hoya cutting or plant they may just live long beyond any expectations you had for them!
