Hoya Curtisii Care: Hoya Curtisii, a compact, trailing species, is found in Thailand, Malaysia and the Philippines according to the University of British Columbia.
It is scientifically known as Hoya curtisii, but it can also be called a Wax Flower and Porcelain Flower.
Hoya curtisii are members of the Apocynaceae family.
The small spade-shaped leaves are green with silver accents. They can be cared for once or twice per season.
Flowers tend to be in clusters, are fragrant, and can come in a variety of colours from light yellow to green/yellow.
This is a small, pretty plant that can be placed in a pot or hanging basket.
It looks great in an outdoor garden or terrarium, as a groundcover in areas that are hot and humid.
Hoya curtisii Care
A well-draining mix of succulent soil or cactus mixed with perlite is required to care for Hoya curtisii. Once the top 2″ has dried, water the plant. Maintain a temperature of 65-75 degrees Fahrenheit (18deg-24degC). The best humidity is above 50%. In spring and summer, fertilize once per month with a balanced liquid fertilizer
Hoya curtisii Care Guide
Hoya Curtisii can grow well in any quality, fast-draining soil.
Because they are epiphytes, their soil needs to be very well-drained.
I love to use succulent soil or a good cactus mixed with perlite.
Two parts soil and one part perlite are all I need to care for my Hoya curtisii. They work great!
Hoya curtisii thrives in bright indirect light, but not direct sun as with many other plants.
They do, however, benefit from some sunlight for a few hours every day, unlike many other plants.
My hoya curtisii maintenance involves moving the plant into direct sunlight for at least two to three hours every day. It thrives.
Hoya Curtisii Watering
Water Hoya curtisii starts at the top, once the top 2 inches of soil are completely dry.
Between watering, I let the top two inches dry completely.
They are more drought-tolerant than others and prefer to live in a bit of dryness.
They hate wet feet, and if I overwater my hoya curtisii, it will let me know that it is unhappy.
Hoya Curtis’s best care is to soak the soil fully once it has dried and then let the water drain out through the holes at the bottom.
Hoya Curtisii plants thrive in temperatures between 65 and 75 degrees Fahrenheit (18deg-24degC) during the day and 60 degrees Fahrenheit (16degC) at night.
Keep them warm, and do not let their temperature fall below 50 degrees Fahrenheit (10 degrees Celsius).
They prefer tropical environments and are considered tropical.
Hoya Curtisii Humidity
Keep the humidity at least 50% for Hoya curtisii.
Hoya curtisii are plants that come from Thailand, Malaysia, and the Philippines. They thrive in humid environments.
My plant likes to have its leaves misted regularly, but not too often. If you live in very dry areas, a humidifier is an important part of Hoya curtisii’s care.
They’ll tolerate it, but they will thrive in a dry environment.
Hoya Curtisii Fertilizer
Fertilize Hoya Curtisii once per month in spring or summer with a liquid fertilizer.
Fertilizing is one of the most important aspects of Hoya curtisii’s care.
For indoor plants, I use a complete fertilizer that contains both macro and micronutrients.
I fertilize once per month during the growing season, and perhaps once to twice during the dormant period.
These plants are fed 1/4 teaspoon of the powder per gallon of water. I get excellent results.
You can also mix organic compost with the soil before it is planted. Then, add organic compost to the soil in the spring as the plant enters its growing season.
A stem cutting is the best way to propagate Hoya curtisii.
It is best to do it in the summer, or early spring.
Place the cut in a glass of water, or in a glass that has some moist soil.
The roots will quickly grow and can then be placed in a container.
Your Hoya curtisii will reach an average height of 2 to 3 inches and a width of 12 inches at maturity.
These plants are compact and small, making them a great choice for urban dwellers who live in tight spaces.
Potting and repotting
My Hoya curtisii always has a good quality, fast-draining pot. A ceramic pot or hanging basket are my favourites.
These small trailing plants are best suited for the hanging basket.
Hoya curtisii loves to be slightly root-bound. It is best not to put it in a larger pot than its roots.
Although they can be kept in the same pot for quite some time, like all plants, eventually they will need to move.
Only transplant one pot to ensure proper Hoya curtisii growth and care.
If your plant is more than four inches tall, you should move it to a six-inch container.
This is a small groundcover plant. It can be prone to problems with insects such as aphids and mealybugs. spider mites and fungus gnats.
These bugs can be controlled by watering properly and making sure that the leaves are not soaked later in the day.
My Hoya curtisii plant care includes spraying the leaves with insecticide soap twice a year: once in the spring and once in mid-summer.
If I don’t have any insecticidal shampoo, I apply neem oil to the leaves. It seems to work well.
Hoya curtisii Propagation Steps
Let’s get a little deeper into propagation.
- It is best to wait for the spring or summer to propagate plants.
- Take care of your plant. When you are trimming or shaping your plant, it is a good time to propagate it. You only need to cut the stem below the point where the air roots are growing. It is easy to see on Hoyas and there are many air roots to choose from.
- Use sharp scissors to make precise cuts on stems you intend to propagate. The node is the point where the aerial root or leaf grows from the stem. You should ensure that your cuttings have a stem. Also, make sure the leaves and stems are vibrant in colour.
- Place the cut ends in a small container of water or a mixture of soil and water. You can also propagate using wet moss. Make a mixture of water and moss by soaking the moss. Place the cut pieces in the moss. Be careful not to break them.
- After the cuttings have established strong roots, you can transplant them into small pots filled with soil and perlite. Two months is a good time to place the cuttings in water.
Another option is layering.
Layering propagation refers to the attachment of the new growth to the parent plant until it develops new roots.
This is done by securing the stem at the node in the soil alongside the mother plant.
After the roots have reached maturity (usually two to three months), you can remove the plant from the pot by using a sharp knife.
It can be planted directly in a new container with 2 parts soil, and 1 part perlite.
My experience shows that a typical cutting will yield a full-sized, blooming plant in less than two years.
Tips and Tricks for Hoya Care
It is important to keep your Hoya curtisii’s humidity levels in mind when caring for them.
My plant thrives when there is a humidifier. This can be used during the winter months, or all year round if my plant is new.
A plastic bag can be used to keep moisture in a cutting by covering it with a plastic bag in the form of a tent.
To test the soil’s moisture, you should dip your finger in it before watering a Hoya Curtisii.
Root rot can be very serious in these plants if they are under-watered. Make sure that your plant is at least partially dry before watering again.
I wait until the topsoil has dried at least 2 inches. I then water the soil until the water runs out through the drainage holes.
Hoya Curtisii’s can be difficult to grow, but they are beautiful flowers.
It responds best to misting water on the leaves every morning and being in direct sunlight for many hours each day.
Leave the stalk after the flowering is over. Sometimes, the stalk will produce more flowers than the original one.
The stalk can be removed by the plant, which will make it use its resources to produce a new one. This may slow down any further blooming.
Hoya curtisii will not flower if it is placed in a larger pot than its root system can handle.
A flowering plant will only produce the best results if it is not too root-bound.

They are generally not toxic to people or animals, but a cat or dog will throw up if the leaves are eaten. All my plants, except cat grass, are kept away from my pets.
Do I need a humidifier to care for my Hoya Kurtisii?
You don’t need one if you live in a humid or naturally moist environment. You might need one if you live in a dry climate. My environment is humid and dry in the winter. I use a humidifier only during winter. Most plants thrive in an environment similar to their native habitat.
