Hoya Krohniana, a rare and uncommon wax plant, has small, heart-shaped leaves with silver markings. It’s also known for its long, vining stems that make it attractive to hang baskets.
It comes in various forms so that you can hear its name mixed with these subspecies.
- Hoya krohniana Eskimo (or Super Eskimo)
- Hoya krohniana Silver (or Super Silver)
- Hoya krohniana Black Leaves
Hoya Krohniana, an epiphyte, has thick leaves that retain water. This allows the plant to withstand lower humidity and dry periods.
It does not have succulent-like leaves. It can be watered like a succulent, but the care of the plant’s other parts is different.
Hoya Krohniana Vs Hoya Lacunosa – What’s the difference?
The Hoya Krohniana’s comparison to the Hoya Lacuna is one of the most common things people say about it.
They look very similar in their growth patterns, so it’s not surprising that there is sometimes confusion. Their long stems and small leaves are the reason for this confusion. You can notice the differences in their foliage if you put them next to each other.
The Hoya Krohniana leaves are heart-shaped, while the Hoya Lacunosa leaves are oval. The leaves of the Hoya Krohniana are more rigid than those of the Lacunosa, which are more flexible and pliable.
Similar to their flowers, the Hoya Krohniana has larger blooms. Despite this, they are very similar. They both look great in hanging baskets.
Hoya Krohniana Care
Hoya Krohniana light requirements.
Light is essential for the Hoya Krohniana. A well-lit area is the best place to keep the Hoya Krohniana indoors.
It’s most happy with indirect light, from medium to bright. It should be kept away from direct sunlight and very strong light.
The plant can tolerate about 1-2 hours of direct sunlight per day, mainly if it is morning sun. If you leave it longer than that, you are putting the plant’s health at risk.
It is vital to provide enough light to your plant to allow it to blossom. A low light level or lack thereof will reduce the likelihood of your plant flowering. Give the Hoya Krohniana at most 5-6 hours of sunlight each day.
Artificial lighting can also be used if you don’t have direct sunlight. You can grow the plant well under grow lights. Keeping the bulb at least 2 inches away from the plant is essential as it can cause damage.
The most crucial difference between grow lights and natural light is how much exposure the plant requires. Artificial light doesn’t cover the same color spectrum as sunlight, so the plant needs at least 10-12 hours of artificial illumination daily.
Hoya Krohniana Temperature
The Hoya Krohniana is a Filipino-based product. It is located in Southeast Asia. It is located in Southeast Asia, as in many other countries. It has tropical weather that is very hot and warm.
December and February are the coldest months of the year. During this period, there is no snow, and temperatures drop to 60 degrees.

It would help if you kept it out of the cold, including any air conditioners or drafty areas close to an open window.
The plant can be grown outdoors in USDA Hardiness Zones 10, 12, and 12. It can be grown outside for up to 365 days per year in these areas. Below 55 degrees, the plant should be brought indoors.
Hoya Krohniana Humidity
The humidity is another aspect of the Philippine weather. It can vary from moderately high to very high, depending on the season and whether it rains.
The humidity at its lowest level is 55%. It can rise to as high as 85% on a rainy day. The humidity should remain between 60% to 75% for the most part.
The humidity level of the Hoya Krohniana is 60% or higher. It can tolerate lower humidity levels due to its thick leaves, which store water.
They are similar to succulents but distinct from them. Don’t treat your Hoya Krohniana in the same manner as succulents. To avoid brown, crispy, or dry leaf tips and edges, keep humidity between 40% and 50%. This indicates that the humidity is too low.
If you live in the desert or an area with very dry air, it is smart to mist your plants regularly.
You can also keep the humidity up by placing the pot on a tray of pebbles or grouping it with other plants.
How Often Do You Water Hoya Krohniana?
The plant can withstand dryness due to its thick leaves. This allows you to have some flexibility if you forget to water. The best way to water Hoya Krohniana’s Hoya Krohniana soil is to let it dry completely before adding water. When the leaves are a little wrinkled, it’s time to water them.
After that, water the pot until it is moistened. This will ensure that roots receive enough moisture as long as the soil has been saturated.
Allow the soil to drain completely, ensuring no water remains in the container. This will stop roots from swimming in water they don’t like.
You should throw away any water in the saucer underneath the pot. The soil will absorb it back eventually. Hoya Krohniana should not be overwatered as it will not tolerate excessive water. It will also tell you if it is having trouble with this, such as dropping its leaves.
Weather plays a vital role in how frequently you water. Make sure to adjust your routine according to the season.
Watering your garden will be done approximately every seven days in the summer. Winter will drop in frequency to about once every two to three weeks.
Hoya Krohniana Potting Soil
Hoya Krohniana needs light, well-drained soil. To avoid overwatering, any excess moisture will quickly drain. The soil’s loose texture will also allow for good air circulation, which is important because epiphytes like to breathe.
For best results, maintain soil pH between 6.0 and 7.0.
It is essential to ensure that your Hoya Krohniana soil has some drainage. This can be achieved with perlite, pumice, or vermiculite.
These are the potting mixtures I have used with my plant. I keep it simple, so I limit the number of ingredients to two or three per recipe.
- 2 parts peatmoss to 1 Part perlite
- 1 part potting mixture with 1 part orchid blend and 1 part perlite
- Mix 1 part potting soil with 1 part succulent & Cactus.
- 1 part coco coir, 1 Part potting soil, and 1 part perlite
- 1 part potting soil, 1 part orchid bark
Here are a few to help you get started with ingredients that you already have. You can also experiment with several of them to find the one that works best in your home.
You can also buy African violet soil or well-draining succulent dirt if you don’t want to make your mix. Both will work well for your plant.
Hoya Krohniana Fertilizer
Hoya Krohniana can be a light feeder, so don’t overfeed it. It is important to feed it plant food, as it will grow faster.
If you use standard houseplant food, you can either weaken the fertilizer or reduce it to half strength. The plant isn’t very fussy about the type of fertilizer you use, but it will be more sensitive to the nutrients you provide.
One month is the best time to feed your plant. It doesn’t have to be fed during winter.
Switch to an Orchid Bloom Booster once your orchid starts to bloom or is about to bloom. This fertilizer has more phosphorus, which aids in flowering.
The latter, however, has more nitrogen, which encourages leaf growth and development. After the blooms have stopped, apply the bloom booster.
Hoya Krohniana Pruning
Hoya Krohniana’s long vine stems are well-known for their small, delicate leaves. It is easy to hang, drape or use as a plant hanging from a basket or a pot.
You can also leave the vines alone, allowing them to grow longer. The prettier the plant looks, the longer it is.
It is also a natural climber, so you can train it to climb a trellis and other wires. These structures will be held by the plant thanks to small aerial roots. It takes time for the Hoya Krohniana to get longer because it is a slow-to-moderate grower.
However, a light pruning is a great way to keep it neat, and in shape you want.
It is important to remember that the peduncles should not be pruned after the flowers have died. This is because Hoya Krohniana (and all hoyas) will make their blooms from old peduncles.
These flowers must be regrown before they can flower again. This could result in you missing a whole growing season of blooms.
How to Propagate Hoya Krohniana
Stem cuttings are the best way to propagate Hoya Krohniana. You can also grow it from seeds or through air layering.
Because it has many stems, this method is the most popular.
Stem propagation allows you to root cuttings in soil, water, or sphagnum. Although each method works differently, they all aim to achieve the same goal: let the cuttings grow roots.
You can therefore choose the way that you want.
How to propagate Hoya Krohniana stem cuttings
- It is best to propagate the plant in early spring or early summer.
- Begin by cutting a stem measuring 4-6 inches in length with at least 1 or 2 nodes and some leaves.
- To expose the nodes, remove the lower leaves.
- Place the cut in well-draining soil (1 % peat, 1 % perlite) that has been moistened. To keep the soil moist, you must water it regularly. Avoid overwatering the soil so that it becomes wet and soggy.
- Place the plant in partial shade in a sunny spot.
- Let it be, and don’t try to change it.
The same steps can be used to propagate the cuttings in sphagnum-moss. You will need to replace the potting mixture with sphagnum moss.
- Water propagation, on the other hand: Place the cut in a glass with water.
- The stem should be submerged so that the nodes are underwater. Keep the leaves above the water. You should remove any leaves that have fallen into the water. They will eventually rot.
- Water should be changed once per week. It is important to keep the water clean and fresh. The plant will get enough oxygen, and no pathogens can grow.
- Within 3-4 weeks, you will see roots starting to develop.
- You can plant the roots once they reach at least 2 inches in length.
How to Transplant or Repot Hoya Krohniana
Because Hoya Krohniana’s root system is not extensive, it is an epiphyte. This means that it may take some time to fill out a pot.
The plant also enjoys being tied to a pot. It will bloom more easily if it is kept in a pot.
This is why you will see Hoya Krohniana underpotted.
Many growers won’t report for more than 2-5 years, sometimes even longer.
It is best to move the plant to a bigger container if it becomes too tight in its pot or if it starts to grow uncontrollably.
Select one that is at least 1-2 inches larger in diameter. Avoid jumping up to more than one size, as this can increase the likelihood of overwatering. It also decreases the possibility of flowering due to its looser nature.
Are Humans, Cats, and Dogs At Risk?
No. No. However, it is important not to allow pets or young children to ingest any parts of the Hoya Krohniana plant.
Although the stems and leaves aren’t poisonous, they can cause stomach discomfort or nausea.
Troubleshooting & Problem Solving
Why isn’t the Hoya Krohniana flowering?
Because only mature plants can bloom, it takes time for Hoya Krohniana flowers to become fully grown. The plant must mature for at least two years before producing flowers.
It is crucial to provide enough light to bloom once it has reached that point. It will be more likely to flower if it is kept root bound.
The Hoya Krohniana is susceptible to pests; the most common are mealybugs. However, spider mites and scale can also be an issue.
These bugs feed on the sap of plants. It is important to identify them early to prevent them from eating the plant’s nutrients and water.
Because these insects can reproduce quickly, it is crucial to do this. If left alone, they can quickly become a full-blown infestation, which can be more challenging to eradicate.
The first-line defense is often to stray them away with water. You can use neem oil and insecticidal soap to get rid of any remaining. It would help if you got them all, as the adults may lay eggs to restart the cycle. Eggs that are left behind by leaves will hatch and become more eggs. The cycle continues.
It would help if you were careful about excess moisture regarding diseases. This can lead to root rot, which is the most serious of all diseases.
You can reduce soil moisture and let the soil dry out before adding water. This will eliminate the possibility of these pathogens becoming a problem.
