Hoya Curtisii


Hoya curtisii is part of a lovely and easy-to-grow family of plants. If you have little room, this is the perfect plant for you.

The spade-shaped leaves have lovely silvery variegation. Wax Plant is the common name for this plant, but any Hoya can be dubbed a Wax Plant! Hoya Curtisii is its scientific name, although it’s also known as a Wax Flower or Porcelain Flower by others.

Green/yellow to light crimson flowers appear in groups and have a pleasant fragrance. In a hanging basket or a conventional pot, it’s a cute tiny plant that looks great. As a ground cover in warm and humid locations, it also looks great in an outdoor garden or terrarium.

How to take care OF Hoya Curtisii

Care instructions for hoya curtisii are provided below –


Plants like Hoya Curtisii thrive in bright light, but not in direct sunshine. Unlike many other plants, they do, however, benefit from a few hours of direct sunlight.

Keeping them in low light is likely to prevent them from flowering. Generally, they can endure direct sunshine as long as it’s bright.

The only exception to this rule would be if you live in an area that receives a lot of direct sunshine.


Hoyas place a high value on watering. Overall, they are drought tolerant and prefer to dry out between waterings rather than be constantly watered.

Whenever I water my plants, I make sure that ALL of the soil is wet. Allow the surplus water to drain out of the pot by using a drainage hole.

Make sure you’re keeping an eye on the dirt, and use your finger to gauge how much it’s dried out. At a minimum, allow the top 1-2 inches of soil to dry out before planting. However, if you do allow the soil to dry out, be sure to rehydrate it afterward. It’s not that difficult!

Hoyas, on the other hand, require well-draining soil to thrive.


Hoyas are epiphytes by nature, and as a result, they require potting mixes that drain very well. As for my Hoyas, I like to use a combination of the following ingredients.

In addition to the succulent or cactus mix, add 1 part of either perlite or 1/4′′ pumice. You’re ready to go when you’ve mixed everything well.

Pumice is my preferred material for Hoyas, but it depends on what I have on hand. In the absence of that, perlite is a good substitute. In either case, your Hoya will benefit from great drainage and be able to dry up in a reasonable length of time.


Fertilizing is one of the most crucial aspects of Hoya Curtisii care. A full fertilizer with macro and micro-ingredients is also used for indoor plants.

Every month during the growing season, and maybe twice during the dormant season, we fertilize. A quarter teaspoon per gallon of water is used to feed these plants, and the results are fantastic.

Also, you can plant the soil with compost and then add organic compost to the top as soon as it starts growing.


At 65-75 degrees Fahrenheit (18°-24°C) during the day and 60 degrees Fahrenheit (16°C) overnight, Hoya Curtisii plants thrive.

It’s important to keep them warm and not allow their temperature to dip below 50°F (10°C).

This species is found in the tropics and prefers a tropical climate.


Considering that your hoya curtisii is a tropical plant, it prefers to be kept moist at all times. To keep your plant happy, sprinkle it with water or use a humidifier if you’re not a fan of humidity in your home. Aim for a humidity level of 50 percent or higher.

Flowering Tips and Guide Hoya Curtisii

To bloom, you may require more than one of these criteria.

  • There is evidence that this plant needs more light than other Hoyas to flower. You’ll need at least a half-day of direct sunlight to let the blooming process move ahead quickly and efficiently.
  • If you have a rootbound plant, it will also encourage your flowering plant to grow. Hoyas prefer tighter pots in general.
  • Temperatures in the evening that are somewhat cooler (but not below 50F) will also encourage blossoming.
  • In the winter, a dry rest period of 4-5 weeks may also be beneficial. While it’s important to keep a check on your Hoya to make sure it doesn’t suffer too much, it should be OK!
  • Cut off the wasted blossom when your plant blooms! The petals will fall off on their own, but the plant will keep whatever is left. After a few years, your plant will rebloom in the same area.

A guide to the propagation of Hoya curtissii

Stem Cutting

To propagate a Hoya Curtissii, stem cutting is the simplest method.

During the summer or early spring, we’ve found that it’s the greatest time to undertake this type of work. Water or very moist soil can be used to soak the cutting.

A few weeks later, the cutting can be transplanted into a pot.

Take a closer look at the process.

  • Propagation is best done in the spring or summer, as is the case with most plants.
  • Verify that your plant is in good condition. When you are pruning or shaping your plant, it’s a fantastic opportunity to propagate it. Cut the stem below the node where the air roots are growing to propagate it. Air roots are easily spotted on Hoyas, which offer a large selection to pick from.
  • Make clean cuts on the stems you wish to utilize for propagation with a sharp pair of scissors. The node is the point at which the leaf or aerial root emerges from the stem’s center. Inspect the stem and leaves of your cuttings to make sure they’re healthy and brilliant in color.
  • In a tiny jar of water, or a watery mixture of soil and water, place the cut ends. Another technique is to use wet moss to proliferate. Assemble your watery mix by soaking the moss and pouring some into the container. As you do this, take caution not to harm the clippings.
  • Transplant the cuttings into tiny pots with soil and perlite once they have robust roots. A suitable time to do this is two months after the cuttings have been placed in water, according to my observations.


It is also possible to propagate by layering. As a result of layering propagation, the new growth remains linked to the parent plant until it develops roots.

At the node of the stem, you’ll need to secure it to a piece of dirt next to the mother plant’s roots.

With a sharp knife, cut the new plant in half and gently remove it from the pot once the roots have grown (two to three months). In a new container with 2 parts soil and 1 part perlite, plant it directly. In my experience, the average clipping will yield a full-sized, blooming plant in two years or less.


Hoya Curtisii: Frequently Asked Questions


As a rule, they are not toxic to animals or people, but cats and dogs ingesting them will vomit because their digestive system cannot break down the leaves. All of my plants, except cat grass, are kept away from my pets.


From seeds, a Hoya Curtissii can be propagated into a new species. The best time to propagate is during the growing season.


There’s no doubt about it, Hoya Curtisii needs humidity. To get the best results, you’ll want to imitate the circumstances in South East Asia. Unlike in the tropics, you don’t need significant humidity for this plant to thrive.


The trailing nature of Hoya Curtisii makes it ideal for a shelf, where it can truly create depth to your display. If you have a south or west-facing window, you should place your Curtisii there as well. They prefer intense light and thrive in warmer climates.


However, a Curtisii is a good plant for beginners because it is easy to care for. If you’re a beginner, our best suggestion is to not overwater this plant.
