Hoya Princess is a hardy plant with stunning succulent-like foliage. This plant has beautiful variegation and the new leaves oftentimes come out with pink variegation. This plant produces blooms that have a chocolate fragrance which is why many people desire this plant.

Hoya Krimson Princess main care tips.

  1. Water. Hoya Krimson Princess should be watered every time the soil dries out. You’ll know when the plant needs water when you try to fold the leaves into a taco. If the leaf can easily fold into a taco, it’s time for a water.
  2. Light. This plant prefers bright indirect sunlight and can even tolerate some direct light. I keep my Princess under T5 Barrina plant grow lights.
  3. Fertilizer. Fertilizer during time growing season and pause during the dormant (typically acwinter) months.
  4. Humidity. This plant prefers higher humidity. I keep my Princess in a greenhouse getting 60%-80% humidity. However, I keep a plant similar to it (Hoya Queen) in regular household humidity (30%) and it’s also doing great.

Here’s what to do to keep your Hoya Krimson Princess thriving.


Hoya Princess prefer bright indirect light and can also be grown under plant grow lights.

I keep my Princess under plant grow lights and they are relatively close to the plant grow light, which means they are getting bright light for roughly 12 hours a day. I find this keeps the variegation and pink color stable.

A plant quite similar to this is the Hoya Queen. I keep my Hoya Queen in a south facing window and it’s happy there. It’s hanging from the ceiling and gets filtered sunlight.


Hoya Princess likes to be watered when the soil is almost dry.

You can tell when this plant needs water by performing the taco test. A houseplant enthusiast online (that I cannot recall the name of) came up with this test. You simply try to fold the Hoya Princess leaf in a taco shape. If it can easily fold into a taco shape, your plant needs water. If the leaf doesn’t fold into a taco shape, your plant has enough water still.

Hoya’s are some of the easiest houseplants in my opinion and don’t need a strict watering schedule.

When watering your Hoya, make sure to aerate the soil with a chopstick. Break up any compacted soil. In nature, worms and insects do this naturally and make it so soil isn’t so compacted. When soil is well aerated, the roots receive more oxygen and get an even distribution of water.


Hoya’s prefer well-draining soil. These plants don’t like to be kept wet or sit in compacted, dense soil.

If you want to repot, you can keep things easy by using equal parts cactus mix, perlite, and orchid bark.

I’m pretty lazy when it comes to replanting plants. For example, I bought my Hoya Princess a few months ago and still haven’t repotted it. It’s thriving in the soil mix it came with from the houseplant store I bought it from. I prefer doing this anyways because it gives the plant a lot of time to get used to my home and its new growing conditions.

If you don’t want to make your own houseplant mix, you can buy pre-made mix like Fox Farm Ocean Forest. This houseplant mix has a blend of high quality ingredients that contain the best ingredients for your plants.


Hoya Krimson Princess do well in homes between the temperatures of 65°F to 90°F (18°C to 32°C).


Hoya Princess need fertilizer just like any other houseplant.

Use a natural or synthetic fertilize to give your plant the nutrients it needs. If you choose to use a synthetic fertilizer, dilute the recipe in half because synthetic fertilizers are quite strong and can kill your plant. With organic, natural fertilizers, you don’t have to worry about diluting the recipe because the fertilizer isn’t nearly as strong as synthetic fertilizers.

Most houseplants go dormant in the winter and this gives the plant time to rest. This means you don’t have to fertilize your plant in the winter and it’s actually recommended you don’t.

However, you might live in a place like I do that doesn’t experience the winter season at all. I find most of my houseplants grow year round and many of them do not go dormant, so I fertilize most of my plants year-round.

I like to use to Liqui-Dirt. Liqui-Dirt is an all purpose plant food that gives your plants all the nutrients they need to grow healthy.


Hoya Princess prefer higher humidity but can be easily acclimated to normal household humidity.

For example, I keep my Hoya Princess in a greenhouse but I keep my Hoya Queen in regular household humidity and it’s doing great. However, I do find that Hoya’s grow a lot faster in high humidity environments.

If you need help increasing humidity, here are my best tips.

  • Put high humidity plants together in a group. When you group high humidity plants around each other, this creates a humid microclimate. The plants will continue to release moisture around each other through transpiration.
  • Place a pebble tray underneath your high humidity plants. I purchased small rocks at a hardware store and placed them on a planter tray. Place your planter on the tray. Put enough water in the tray until it hits the planter bottom and the water will evaporate around the plant.
  • Purchase a humidifier and run it daily near your houseplants
  • Place high-humidity plants in your bathroom. I place certain high humidity plants in my shower and they’re thriving.


Propagating a Hoya Princess is simple. The easiest method is taking a cutting that has both leaves and a stem.

Root the stem in water and you’ll soon see roots growing. Once you see visible roots about 2 inches long, move the plant to your preferred substrate.

Place your cutting in bright indirect light and not in a dark corner. This will speed up the rooting process. You should see root development in about one month.

You can also take cuttings of the leaves with a petiole and place the petiole in water, but I find this to be a process that fails most of the time.

Common pests

Hoya Princess is known for being susceptible to mealybugs. This is why it’s important to use a pest preventive and regularly check your houseplants for pests before the problem gets out of control.

If you find mealy bugs on your houseplant, quarantine the plant immediately. Keep away from all other houseplants. Grab a q-tip and 70% rubbing alcohol and gently wipe off any sign of mealy bug.

Other pests drawn to the Hoya Princess include scale and aphids. These pests can hurt your plant which is why prevention is key.

To help prevent any pest infestations on your plant, her are my best tips.

  • Regularly check your plants for pests. This is also a great time to clean your plants.
  • Keep your plant looking healthy by cutting off dead foliage.
  • Use a natural or synthetic pest preventative to keep pests at bay.
  • Quarantine new houseplants for two weeks before bringing them around your other houseplants.

If you find a houseplant has pests, quarantine the plant away from your houseplants. Clean the plant with an organic or nonorganic insecticide.

I use Bonide Systemic Granules on my plants as a preventative. All you do is sprinkle the systemic granules on top of the soil and let it do its magic. This product is extremely effective for fungus gnats.

Bonide Systemic Granules are a great way to get rid of unwanted pests.

Common issues

Brown tips: If your Hoya Princess has brown tips, you may be overwatering your plant. Cut back on water and only water when the plant feels very light. Or use the fun taco method test that will help you figure out when to water.

Yellowing leaves: If your Hoya Princess has yellow leaves, you may be overwatering or the soil doesn’t have proper drainage. If the soil doesn’t have proper drainage, repot and use equal parts cactus, orchid bark, and perlite. You can also move your Hoya Princess to a semi-hydroponics like leca or lechuza pon.

Curly leaves: If your Hoya Princess has curling leaves, it’s either due to overwatering or underwatering. I know, helpful right. This is why many people move this plant to leca or lechuza pon.
