How to Grow Hoya Pubicalyx

H. pubicalyx, also known as the wax plant, is a beautiful and easy-to-care-for houseplant. Native to Southeast Asia and the Philippines, it is a climbing or trailing plant that can reach up to 10 feet in length. The leaves are dark green and glossy, and the flowers are pink. Hoya pubicalyx is a relatively slow grower, but with proper care, it can bloom multiple times a year.

Here are some tips for growing the wax plant indoors. 


If you’re looking for a fast and easy way to propagate H. pubicalyx, stem cuttings are the way to go. 

First, choose a healthy stem that has at least 2-3 nodes (the small bumps where leaves are attached). Next, using a sharp knife or shears, cut the stem just below a node. Once you have your cutting, strip off any lower leaves so that only the upper leaves remain. Finally, place the cutting in a well-drained potting mix and water lightly. 

Keep the soil moist but not soggy, and in 6-8 weeks your cutting should have rooted and be ready to transplant.

Another method of propagation is by leaf cuttings. Again, choose a healthy leaf and cut it off at the base, near the stem. Dip the cut end in rooting hormone and plant it in moistened potting mix. Place the pot in a warm, bright location and keep the soil moist but not soggy. New plants will emerge from the soil shortly. 


When it comes to soil type, H. pubicalyx prefers well-drained, sandy loam soil that is high in organic matter. The soil should also be slightly acidic, with a pH level between 6.0 and 7.0. If you are unsure about the pH level of your soil, you can test it using a soil test kit. 

Once you have determined that your soil is suitable for Hoya Pubicalyx splash, be sure to water it regularly and fertilize it every two weeks during the growing season. 


Wax plants are relatively easy to care for, but they do require regular pruning in order to keep them looking their best. Here are some tips on how to prune your H. pubicalyx.

Start by trimming back any long or leggy stems. This will help to encourage new growth and prevent the plant from becoming too top-heavy.

Next, remove any dead or dying leaves or stems. This will help improve air circulation and prevent disease from spreading.

Finally, cut back any stems that are crossing or rubbing against each other. This will promote better growing conditions and allow the plant to fill out evenly.

With just a little bit of effort, you can keep your H. pubicalyx looking healthy and beautiful all year round!

Hoya Pubicalyx, or Wax Flowers, are beautiful, easy-to-grow houseplants that are known for their clusters of small, waxy flowers. If you’re thinking about repotting or transplanting your Hoya Pubicalyx, there are a few things you need to keep in mind. 

First, choose a pot that is only slightly larger than the current one. H. pubicalyx doesn’t like to be pot-bound, but too large of a pot can lead to root rot. Second, use a well-draining potting mix. A mix of peat moss, perlite, and sand is ideal. Third, water your plant thoroughly before repotting or transplanting. 

This will help to prevent shock. And finally, be careful not to damage the roots when you’re repotting or transplanting. With a little care, your H. pubicalyx will thrive in its new home.

How to Care for Hoya Pubicalyx

Most hoya plants are easy to grow, but the H. pubicalyx can be a bit more challenging. This article will provide Hoya Pubicalyx care tips so that you can enjoy its beautiful blooms.


During the growing season, you should water your H. pubicalyx regularly to keep the soil moist but not soggy. Allow the top 1-2 inches of soil to dry out between watering. 

During the winter months, reduce watering to once or twice a month, allowing the soil to almost dry out between watering. If you notice that your plant is wilting or the leaves are turning yellow, this is a sign that it’s not getting enough water. 

Give your plant a good soak and then allow the excess water to drain off before returning it to its spot.


This plant is relatively easy to care for, and will thrive in most home environments. However, it is important to provide the plant with the ideal amount of sunlight. Too much sunlight can scorch the leaves, while too little sunlight will cause the plant to become leggy and produce fewer flowers. 

The best way to ensure that your Pubicalyx gets the ideal amount of sunlight is to place it near an east- or west-facing window. This will provide the plant with bright, indirect light throughout the day.

Temperature and Humidity

If you’re thinking of adding a H. pubicalyx to your home, it’s important to create an environment that mimics its natural habitat. These plants prefer warm temperatures and high humidity levels. 

During the day, the ideal temperature range is between 70 and 85 degrees Fahrenheit. At night, the temperature should not drop below 60 degrees. 

As for humidity, aim for a level of 60-80%. If your home is particularly dry, you may need to invest in a humidifier. 


Fertilizer is an important part of plant care, and H. pubicalyx is no exception. Like all plants, it requires nutrients to thrive. 

A well-balanced fertilizer will provide the necessary minerals for healthy growth, including nitrogen, phosphorus, and potassium. However, it’s important to be careful not to over-fertilize, as this can damage the roots and leave the plant vulnerable to pests and diseases. 

When applying fertilizer, be sure to follow the manufacturer’s instructions to ensure that your H. pubicalyx gets the nutrients it needs without being overloaded.

Pest and diseases

While H. pubicalyx is generally a low-maintenance plant, it can be susceptible to pests and diseases. Common pests include mealybugs, aphids, and spider mites. Fungal diseases such as powdery mildew and leaf spot can also affect the health of the plant. To prevent problems, it is important to maintain proper watering and humidity levels and to regularly inspect your plant for signs of pests or disease. 


Mealybugs are small, wingless pests that feed on the sap of plants. They are often found in clusters on stems and leaves, and they can cause yellowing, stunted growth, and leaf drop. 

Mealybugs can be difficult to control because they reproduce quickly and they often hide in hard-to-reach places. 

However, there are a few things you can do to get rid of mealybugs. First, isolate any infected plants so that the bugs don’t spread to your other houseplants. Then, gently wash the bugs off with a solution of soap and water. 

You can also try using an insecticidal spray or placing sticky traps around the plant. 


Aphids are small, pear-shaped insects that can cause damage to houseplants. They feed on plant sap, which can weaken the plant and make it more susceptible to disease. 

Aphids can also spread diseases from one plant to another. There are a number of ways to prevent and deal with aphids on houseplants. One way to prevent them is to avoid overcrowding your plants. 

Aphids thrive in crowded conditions and can easily spread from one plant to another. Another way to prevent them is to keep your plants healthy. Healthy plants are less likely to be attacked by aphids. If you do find aphids on your plants, there are a number of ways to deal with them. 

You can remove them by hand or with a soft cloth. You can also spray them with water or an insecticide. If the infestation is severe, you may need to discard the affected plant. By taking some simple precautions, you can help prevent and deal with aphids on your houseplants.

Spider Mites

Spider mites are tiny pests that can cause big problems for houseplants. These pests feed on plant sap, and their feeding can cause leaves to turn yellow, brown, and brittle. 

Spider mites are especially fond of succulent plants, but they can infect any type of houseplant. To prevent an infestation, it is important to inspect your plants regularly and quarantine any new plants before adding them to your collection. 

If you do find spider mites on your plants, there are a few things you can do to get rid of them. One option is to spray the plants with water to knock the spider mites off. You can also try using a powerful vacuum cleaner to suck up the spider mites. 

For more persistent infestations, you may need to use a pesticide. Be sure to follow the instructions carefully and only use pesticides as a last resort. 

Powdery Mildew

Powdery mildew is a fungal disease that appears as a white or gray powder on the leaves of affected plants. While powdery mildew does not usually kill plants, it can cause them to become stunted and weakened. If left untreated, it can also spread to other houseplants. There are a few simple steps that can be taken to prevent powdery mildew from developing in the first place. 

Make sure that your plants have adequate airflow by spacing them out appropriately and avoiding overcrowding. Second, water the plants at the base rather than wetting the leaves. Finally, remove any affected leaves as soon as possible to prevent the fungus from spreading. 

If powdery mildew does appear, it can be treated with a number of different products, including fungicides and home remedies.

Leaf Spot

Leaf spot is a common problem that can affect houseplants. The spots are usually caused by fungal or bacterial pathogens that enter the plant through wounds in the leaves. These pathogens can quickly spread, causing extensive damage to the plant. 

Left unchecked, leaf spot can cause the leaves to fall off, leaving the plant vulnerable to other pests and diseases. There are a few simple steps that gardeners can take to prevent and deal with leaf spot. 

First, it is important to water plants at the base rather than from above. This will help to reduce the amount of water that splashes onto the leaves, which can spread pathogens. Secondly, gardeners should avoid using anything that might damage the leaves, such as sharp equipment or chemicals. 

If possible, use sterile tools when handling the plant. Finally, if leaf spot does occur, it is important to remove affected leaves as soon as possible. This will help to prevent the spread of the disease and give the plant a chance to recover.
