Hoya Carnosa Krimson Queen is the perfect plant to add to your home if you want a beautiful hanging plant. This is an easygoing plant that will thrive in your home with these key caring tips.

Hoya Carnosa Krimson Queen plant care tips.

  1. Water. Water 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. If you hang this plant, make sure that the top of the plant gets sunlight.
  3. Fertilizer. Fertilizer during growing season and pause during the dormant (winter) months. I fertilize every watering (once a week) but you can choose to do bi-weekly or once a month.
  4. Humidity. This plant prefers humidity ranges of 30%. I have mine in a room with less than 30% humidity and it is very happy.

Now let’s dig a little deeper so you know how to make sure your plant not only survives bu thrives in its new home.

Light

Hoya Carnosa Krimson Queen thrive in bright indirect sunlight. It’s important that the top of your plant gets sunlight, so if you’re hanging this plant, put it in an optimal spot where the entire plant is getting bright indirect sunlight.

These plants can even do with some direct sunlight, but not hours on end. If you give your plant at least an hour of direct sunlight, you may get lucky enough to see some blooms.

I have my Hoya Carnosa Krimson Queen hanging in a southwest facing window and she’s a happy girl.

If you don’t have sufficient lighting, you can use plant grow lights. I use T5 Barrina grow lights and have them on a timer running for 13 hours a day.

Water

Water your Hoya Carnosa Krimson Queen when the soil is dried out. Hoya’s are very easy when it comes to watering because you can feel them and know if it needs a watering using the taco method. You may have heard of the taco method, if not, I’ll tell you.

The taco method is simple. Grab a leaf gently and try to fold it into a taco. If the leaf folds into a taco pretty easily, it’s time for a good thorough watering. If you cannot fold the leaf into a taco shape, your plant does not need water yet.

These plants are drought tolerant and amazing for beginner indoor gardeners because they’re almost impossible to kill.

I always water my plants using filtered water from our reverse osmosis system. I do not use tap water due to the chlorine and fluoride properties as this can damage the plant. This goes for most houseplants in general.

When watering your Hoya, make sure to aerate the soil using 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, it can get more oxygen and even distribution of water.

Soil

Make sure your soil mix is well aerated by using perlite, coco coir or orchid bark. Hoya Carnosa’s do not like to feel wet and are even quite prone to root rot if it’s sitting in water.

Think about how you would pot your cacti and succulents, it’s quite the same for this Hoya variety.

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

I purchased my plant in a 6 inch pot and still haven’t repotted it. My plant is thriving and doesn’t need to be repotted yet. I get most of my houseplants at a local independently owned plant shop and trust the soil recipe they use.

If you want to repot your plant, a high quality potting mix is Fox Farm Ocean Forest. This potting mix contains a blend of high quality ingredients perfect for houseplants.

Temperature

Hoya Carnosa Krimson Queen’s do well in any home that is between temperatures of 65°F to 90°F (18°C to 32°C). Do not place this plant near drafty areas like vents, windows, or doors.

Fertilizer

If you are using a non-organic, synthetic fertilizer, it’s always recommended to dilute the recipe in half because of how strong the N-P-K ratios are. If you are using an organic fertilizer, you typically do not have to worry about diluting the recipe because the N-P-K ratio is so low.

When using fertilizer, make sure to pause during the dormant months. Your plants are resting and do not need fertilizer during this time. Your plant is dormant if it is no longer growing new leaves.

Depending on where you live, your plant will be dormant at different times. For example, I live in the desert and find that my plants rarely go dormant so I feed fertilizer year-round.

I love using Liqui-Dirt. This is basically liquid gold in the plant world because it makes plants grow like crazy.

Humidity

Hoya Carnosa Krimson Queen prefer humidity levels above 50%, but like I mentioned earlier, my plant is in a cacti room that isn’t very humid at all, yet she is thriving.

If you need help increasing your house’s 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.
  • Mist your plant. Depending on where you live you may not need to mist. I live in a very dry climate so I choose to because anything helps.
  • Place high-humidity plants in your bathroom. I place certain high humidity plants in my shower and they’re thriving.
Use a hygrometer to check the humidity around your plants.

Propagation

Propagate a Hoya Carnosa Krimson Queen by cutting off the stem with a couple of leaves on it already. Hoyas do not have nodes like most plants and instead can grow roots anywhere on the stem.

Place your cutting in water or soil. If kept in water, do not get the leaves wet as they can rot easily. If kept in soil, keep the soil a little moist throughout the propagation process.

I recommend cutting a couple of stems to increase your chances of rooting. Place both cuttings in the same water and this will increase the chances of rooting hormone working on the cuttings.

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.

As you can see below, I’m trying to propagate my Hoya Carnosa Krimson Queen with a leaf cutting. It has not been successful so far, so I do not recommend it. Go the stem route.

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. Check your plant regularly as mealybug larvae are very small and you may have missed them.

  • Regularly check your plants for pests. This is also a great time to clean your plants.
  • Cut off dead leaves.

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

I use Bonide Systemic on my plants as a preventative and Captain Jacks to kill pests. I spray the plant outside and wipe down the leaves and stems with rubbing alcohol. Make sure to check all of your other plants as it is easy for pests to spread.

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

Common issues

Brown tips: If your Hoya Carnosa Krimson Queen 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.

Curly leaves: If your Hoya has curling leaves, it’s either due to overwatering or underwatering. I know, helpful right.
