Hoya Pubicalyx Care: A Guide to Caring for Your Hoya Plant

There are many plants that can be found in homes and offices throughout the world. One of these plants is the Hoya Pubicalyx plant, which has a beautiful flower on top of it. If you have one in your home or office, then this article will provide you with information about how to care for your Hoya plant so that it thrives.

Hoya Pubicalyx

Biology of the Hoya Pubicalyx

Hoya Pubicalyx is a vine-like plant that comes from the rainforest of East Africa. It’s found in forested areas and usually grows up in tree trunks or on rocky cliffs.

The scientific name for Hoya Pubicalyx means ‘pubic hair’ because it has pubescence (fine, downy hair) on the underside of its leaves.


A Hoya plant is succulent, and as such requires soil that can hold water. The best option for most people is to use cactus/succulents mix or potting soil mixed with sand. If you are not sure which type of soil your plants need, try using the standard all-purpose mixture unless there are specific instructions from the manufacturer of the potting mix otherwise.

Watering Your Plant

Keep the soil consistently moist during both active growth and dormancy, but be careful not to overwater your plant or allow it to sit in water for too long of a time period (waterlogged roots will rot). The most common cause of hoya death is root rot so make sure you always check that there’s at least one inch between the surface of the potting mix and the top of the pot.

If you notice any signs with browning edges on leaves, this could indicate overwatering or dry air; adjust accordingly by giving slightly less light exposure, using more frequent mistings when needed, adjusting humidity levels if necessary, etc.


These plants are not cold tolerant and should be grown in a warm environment. Temperatures below 50 degrees Fahrenheit will kill the plant quickly. HOYAS like to absorb heat and light from lamps or sunlight through their leaves (called phototropism), so they’ll need an east-facing window for at least six hours of direct sun exposure per day.

The best way to avoid drafts is by planting your Hoyas close enough that you can use these windowsills as a natural buffer between them and any air currents coming off walls or heating vents nearby. If this isn’t possible, using insulated panels on the draughtiest areas may help save the plant’s life…

Light Requirements

Hoya plants enjoy lots of natural light indoors. Try to find a spot that faces plenty of sunlight, but avoid placing them in direct sun or they may burn and shrivel up.

It is best to keep the plant on the south side window, where it will get filtered sunshine during the winter months as well as an abundance of summertime rays.

Natural window light should be sufficient for most houseplant hoyas if placed within 18 – 24 inches from the windowsill with indirect exposure (not too much shade). The leaves are sensitive to extreme heat and dry air; therefore use caution when choosing your indoor location (i.e., don’t put a hoya near a heating duct). They can tolerate low light conditions as long as they are kept moist.


This hoya plant is a low-light houseplant that likes to be semi-dry during the winter. To prevent over or under watering, use an organic fertilizer every other month in spring and summer, and once per year in the fall/winter.

We like to recommend using Dyna Gro’s Biological Grower’s Special Formula 13-13-13 (this can be found at your local nursery) for these plants because it provides them all of their necessary nutrients while being environmentally friendly. Just apply according to package instructions on the label. It will only take about two teaspoons each time you fertilize this type of hoya plant.


Humidity is very important for the Hoya, so it’s best to use a humidity tray and keep your plant on top of that. This will allow for more condensation to build up inside the pot and help maintain moisture levels in the soil. You can also mist or spray water onto the leaves when they are dry (once per week) but be mindful not to overdo this as you might damage plants with sensitive skin.

Pruning and Upkeep

Pruning should be done in the spring – as new growth starts sprouting from buds on the stem. It is best performed towards the end of February when temperatures start getting consistently above 60 degrees Fahrenheit (16ºC).

Cut back only about one-third at each cut; this ensures that air and nutrients can still get to all parts of the plant. This also fosters branching out with more stems for future flowers.

When cutting off any dead or damaged leaves use sharp scissors or clippers, never break them off by hand- they’ll remain attached and sap energy from the plant. This process should be done once a year, in order to keep your Hoya Pubicalyx healthy and beautiful!


Blooms on this plant are not always the same color as those at its base. The bloom stems grow from nodes called “crowns” that form on older leaves near the plant’s center and then lengthen outwards, bringing with them new leaf buds which will eventually turn into blooms.

These crowns can be removed by pinching or cutting–at least every few months for plants in the active growth phase to ensure they receive plenty of light for their future blooms.

Potting Soil

The potting soil or dirt should be a sterile, well-draining, and well-aerated mix. This means the pots will dry out faster but roots won’t rot as easily. You want to use quality commercial soil that has been sterilized with steam for good rooting results.

The pot should have holes in it so air can penetrate its surface area where bacteria could grow if they are present in the container. A bottom drain hole is also crucial because this allows excess water to escape over time which prevents root rot from happening too quickly like when overwatering occurs often by accident (especially if you live in an apartment).

Hoya Pubicalyx plants love high humidity environments and require some amount of watering daily, especially if they are growing in a low light location.


Hoya plants are propagated by cuttings. To propagate a Hoya plant, take the cutting and place it in an appropriate rooting medium so that the end of the cutting is slightly above ground level. Planting time is dependent on temperature-it’s best to wait for winter or early spring when temperatures are cooler because they help promote root growth.

Growing From Seeds

Growing from seeds is the most popular way to grow Hoyas. It takes a long time for plants to mature, but it’s worth the wait because once they are ready you will have even more Hoya varieties than when starting with an established plant.

The best thing about growing from seed is that you can place your bets on which traits or colorations might be carried by each new generation of plants and then choose accordingly. This method also allows less experienced growers who may not yet have acquired all their desired strains (including valuable rare ones) to still produce them without having to purchase cuttings from other collectors in order to reproduce them.

How To Germinate Your Seeds:

  • Fill up glass jars or plastic containers with soil.
  • Place the seeds on top of the surface and cover them up to a depth of about one centimeter.
  • At this point, some growers prefer to place their seedlings under fluorescent lights for 18 hours per day while others will keep them in indirect light such as underneath cabinets or near windows during periods when they are not harvesting sunlight – preferably at least 14 hours per day (if you have no choice but to use artificial lighting).
  • It is important that once your plants start sprouting, they should be placed outside within a week so that there is enough time for the plant’s roots to grow stronger before winter sets in. Many people find it easiest just to put their trays directly outdoors once all chance of frost is past.
  • When the seedlings are ready, they should be placed outside in a shady place for at least one hour per day to help them adjust gradually and get used to their new environment.

Common pest and diseases for Hoya Pubicalyx

There are many pests and diseases that will affect a Hoya Pubicalyx plant. The most common pest is the spider mite, which can cause damage to leaves as well as webs on plants.

Whiteflies infestations can be devastating for new growths or branches of older plants. Mealybugs also like to attack the foliage but only leave behind small spots instead of webbing. One disease you may find is powdery mildew, which grows over your leaf surface and blocks out any light from reaching its lower areas; this leads to dead patches at its base with brown spots throughout.”

Frequently asked questions about Hoya Pubicalyx care

Q: What’s the difference between Hoya Pubicalyx and other Hoyas?

A: The leaves of Hoya Pubicalyx are covered in tiny hairs that produce a velvety texture, which is why it was named after the Latin word for “pubis”, meaning hair covering the genital area. Its flowers have prominent stamens or male reproductive organs.

Regular care with watering will help to maintain its glossy appearance by keeping its surface free from dust particles or mildew buildup. It grows best at room temperature so avoid placing near windowsills where cold air may combine with direct sunlight to dry out any moisture on the plant’s surfaces.

Q: How do you care for your Hoyas?

A: Hoyas can be planted in just about any well-drained soil mix or potting media that contains appropriate fertilizer as needed to maintain healthy growth. The type of pot used will depend on how big the plant gets when it matures. Q: Can my Hoyas go outside? (Hint) Yes! They need full sun exposure to thrive and grow properly. If they’re not getting enough light, then water them less often because too much water can rot their roots over time.

A: Hoyas need full sun exposure to thrive and grow properly. If they’re not getting enough light, then water them less often because too much water can rot their roots over time.

Q: I have a Hoya Pubicalyx plant that has a lot of brown leaves around the edges what do I do?

A: It sounds like you might be watering your plants too frequently or are overwatering them in general. Cut back on how often you are giving it any additional water from now on and check for signs of wilting if after being without extra moisture for more than two weeks there is no improvement – see below! Anything else may also cause leaf discoloration such as lack of sunlight, so be sure that your plant is getting enough sunlight.


Hoya plant care is easy, but it does take a little bit of time and attention. Hoya plants are perfect for those that want to add color into their lives without having to worry about other issues like watering or sunlight. This post has covered the basics of how to grow your hoya in an ideal environment so you can enjoy the beauty these flowers offer year-round!
