Hoya Fungii: Ultimate Grow & Care Guide

Hoya fungii is an excellent choice if you want a plant that flourishes with very little care. The plant has good pest and disease resistance, and it can survive even when neglected.

Thus, if you are a newbie or are someone who has killed a lot of plants, start with Hoya fungii. It is a perfect plant for you.

This being said, I do not mean that you can expect your Hoya fungii to thrive on any condition. They have a specific care regimen that you should follow.

Here are the parameters and ideal conditions you need to maintain for Hoya fungii.

Parameters Favorable Conditions
Sunlight Medium bright indirect sunlight
Watering Once in a week or 15-20 days in winter.
Temperature 50 to 77 degrees Fahrenheit.
Humidity 50% or more
Potting Mix Well-draining, chunky, coarse, nutrient rich soil mix
Soil pH6.1 to 7.5
Fertilization Monthly fertilization with nitrogen and phosphorous fertilizer or a balanced fertilizer
Pot Type Terracotta or coconut husk pot, 1-2 inches larger than the rootball

Pruning Prune only dead, damaged, and unmanageable parts
Repotting Once in 2-3 years
Propagation Via stem cuttings and seed germination
Common Pests Mealybugs, Aphids, and Spider mites
Common Diseases Bortyris Blight, Sooty mold, and Root rot

1. Adequate Sunlight and Proper Location

Hoya fungii adores a plethora of indirect sunlight. Hence, the best location for it will be an eastern-facing window reflecting morning sunlight.

However, you can keep them within 1-3 feet from a southern or western facing window.

But, ensure that it does not receive prolonged afternoon or midday sunlight. Harsh sunlight causes dying yellowing and browning of leaf margins.

It is best to provide Hoya fungii with 7-10 hours of dappled light.

Sunlight for Indoor Plants

Do not deprive them of light, as low light causes drooping and wilting of leaves while reducing the photosynthesis rate.

Reduction in photosynthesis hampers other physiological functioning of the plant.

Besides, it produces smaller leaves in low light, and the plant experiences stunted growth.

Pro Tip: Rotate the plant once in 10-15 days to obtain balanced growth and to avoid bending of the plant.

Tips to Improve Lighting Conditions

  • If you are growing them indoors, provide 70-80% of the full light intensity. For outdoor settings, provide 30-40% of the full light intensity.
  • Avoid direct sunlight and grow them under shades for outdoor settings.
  • Protect your plant from direct rays. You can block them using a light curtain.
  • Do not shift Hoya from a brighter location to a low-light place.
  • Use artificial light if your place has low light intensity. It is also beneficial to use artificial lights during winter as light intensity is naturally low.

If you are using artificial grow lights, ensure to provide your Hoya fungii with about 7-10 hours of full-spectrum light.

Besides, keep them within 20-30 cm from the light source.

2. Moderate Watering

Hoya fungii adores soil moisture but remember; they do not like to bathe in a pool of water. I consider watering my Hoyas once the top 2/3 inches of the soil is dry.

So, it would be best if you water your Hoya fungii plant once a week in summer and about 15-20 days in winter.

The most common problem many plant parents face is over-watering. Factors like temperature, pressure, and moisture alter a plant’s watering requirements.

There are a couple of methods to check your plant’s water requirement.

Simply insert a stick 2-3 inches deep in the soil. If it comes dry, water the plant thoroughly; else, wait for a couple of days for the soil to dry.

Next, you can lift your pot. Does it feel light? If so, it might be an indicator that the soil is dry, and you need to water them. Generally, dry soil is lighter compared to wet.

But, if these hacks do not ring your bell, you can always use a moisture meter. It gives you accurate readings to quickly figure out the watering requirements of your plant.

On rare occasions, moisture meters might give an error reading. It is because its reading is largely affected by the salts content in soil mixes like pumice, perlite, barks, and charcoal.

Signs of Watering Issues

In most cases, both under-watered and over-watered Hoya fungii show similar signs.

Generally, it is accompanied by yellowing, limping, drooping, wilting, and foliage discoloration.

But, on closer inspection, you can easily find out the underlying cause. If the leaves are limp and mushy along with sudden wilting, it is likely that your plant is over-watered.

Overwatering the Snake Plant

Over-watering blocks the tiny air pockets in the soil and thus causes anaerobic activities. Such bacterial growth causes root rot and a foul smell in the soil.

In contrast, the leaves of underwater Hoya are dry, crispy, and contain brown-yellow patches, especially along the leaf’s edge.

Tips to Water Hoya Fungii Properly

  • Water your Hoya fungii according to its requirement rather than following a tight schedule.
  • Always water them thoroughly until the water does not run out of the drainage holes.
  • Use either tepid or room temperature water for Hoyas.
  • Reduce the watering frequency to half during winter.
  •  Use salt-free water as high salt content damages the plant’s root.

3. Warm Tempetarre

Based on their instinctive character, Hoya fungii adores slightly warm temperatures.

It is ideal for providing your Hoya fungii plant with a temperature of about 65 – 75Fahrenheit. 

Hoyas are irresistible to cold and hot stress. So, be mindful that you do not expose them to temperature extremities.

Extremely hot temperature above 80F causes stunted growth, yellowing and discoloration of leaves, excessive moisture loss from leaves, and quick-drying of soil.

Since Hoyas are adapted to grow in high humidity and consistently moist soil, it is always best to avoid high temperatures and sunny locations.

Besides, Hoya needs a slightly warm temperate to bloom. If your plant is experiencing temperature stress, there is a high chance of them not blooming.

You might have noticed that Hoya fungii produce flowers from spring to autumn when the temperature is perfectly warm.

Likewise, cold stress can cause the freezing of water present in the cells. It exerts high pressure and might also cause rupturing of cells.

Such severe damage to the cell causes sudden wilting, hindrance in physiological processes, and sometimes even the killing of the plant.

Tips to Maintain Ideal Temperature

  • Always protect Hoya from heat stress. You can save them from harsh light that intensifies the temperature stress by preventing direct sun rays.
  • You can counterbalance moisture loss resulting from high temperatures in Hoyas by increasing humidity.
  • Consider buying frost blankets and heating pads to protect plants from cold.
  • Similarly, you can insulate the plant from cold. Add mulch such as dried grass and straw on top of the soil to prevent temperature loss.
  • Avoid drafty areas and heating and cooling vents like radiators and heaters.
  • Using a greenhouse and terrarium to keep the Hoyas is an excellent way to protect them from cold.
  • Never leave your Hoya fungii outdoors during cold nights.

Did you know artificial grow lights are helpful in maintaining temperature besides light?

Interestingly, a LED light of about 500 w is capable of producing about 1,877 heat BTU per hour.

4. Moderate to High Humidity

Hoya fungii naturally thrives well in high humid areas. So, consider growing them in an area supporting about 70% of the relative humidity.

However, there are no hard and fast rules for Hoyas’ humidity. They can grow in an average indoor humidity of about 50%.

Nevertheless, it is always best to maintain high humidity for their best growth.

Low humidity brings problems such as shriveling, curling, browning, and crisping leaves. Prolonged low humidity might as cause drooping and wilting of stems in Hoya fungii.

Note: High humidity might also cause bacterial and fungal infections in the plant. Maintaining high airflow protects the plant from mold and other fungal infections.

Tips to Maintain Ideal Humidity for Hoya Fungii

  • The most effective method to maintain high humidity is using an electric humidifier. It is slightly costly compared to other ways; however, it is always best to invest in a humidifier if you own many plants.
  • Mist leaves in a frequency of 3-4 days in the morning. Avoid misting of leaves during the evening and at night.
  • Next, you can group your plants. But, I do not generally opt for this method as it increases the chances of spreading pests and diseases.
  • Alternatively, you can use the wet pebble tray method. It maintains humidity as the water in the tray evaporates.
  • Similarly, place the plant in the kitchen and bathroom as the humidity is naturally high.

5. Well-Draining Soil

You need a suitable base for your Hoya to thrive best. Avoid using regular garden soil or any other soil that retains high moisture for a more extended period.

Hoya fungii is a semi-succulent plant; hence, poorly draining soil makes them vulnerable to root rot.

Consider using fast-draining, coarse, chunky, nutrition-rich soil for Hoya fungii that retains optimal water while draining the rest out.

If you seek commercial mixes, use any cacti and succulent mixes and orchids mix combined in equal portions.

But, if you want to have your ideal soil mix for hoya fungii, here is the recipe you can follow.

  • Mix 1 part of all-purpose soil or orchid mix
  • 1 part of perlite
  • 1/2 part of coco coir or peat moss
  • 1/3 part of coarse sand
  • 1/3 part of organic compost.

Alternatively, you can mix barks, charcoal, rice husk, dried leaves, and grass to make the soil light and porous.

The following important factor in caring for is soil pH. pH regulates the rate of nutrient absorption and also filters toxins.

Thus, maintain an ideal soil mild acidic to neutral soil pH of about 6.1 to 7.5.

6. Monthly Fertilization

Is your Hoya fungii dull, leggy, discolored, wilted, and drooped? Well, it is plausible that the plant lacks nutrients.

Plants need all types of nutrients for their proper growth. It is essential to supply your Hoya fungii with both macro-nutrients and micro-nutrients for proper growth.

Using either a balanced fertilizer with 10-10-10 or a blooming fertilizer rich in phosphorous like 7-9-5 is best for Hoya fungii.

I generally use organic fertilizers for all of my plants as it is does not deplete soil quality. But, you can always go for synthetic fertilizers.

Besides, you can use nutritional boost solutions to encourage plant growth.

Mix  5ml of nutrition in 1 liter of water and spray it all over your Hoyas. It supplies the plant with essential boots to produce new and healthy foliage.

Tips to Fertilize Hoya Fungii Properly

  • Water the plant before fertilizing them as it enhances better nutrition absorption.
  • Always dilute the strength to 1/4th or half before using them.
  • Avoid spraying fertilizer on foliage and stems. Apply it only to the soil.
  • Fertilize the plant only during the growing season. Avoid fertilization during winter.

Avoid over-fertilizing your Hoyas. Every time you fertilize your plant, it absorbs essential nutrients and leaves salt residue in the soil.

That accumulated fertilizer salts burn roots and leaves, altering the soil pH.

How to Treat Over-Fertilized Hoya Fungii?

If you see root burns and burns along the margin of newer foliage, your plant is probably over-fertilized.

The simple and the most effective method to treat over-fertilized plants is to drench them in a pool of water.

Unhealthy Tradescantia Tricolor
Leaf Burn Due to Over-fertilization

Take a shallow container with tepid salt-free water and place the plant into it. Leave it for about 15-30 minutes for the salts to flush out.

Now, take the plant out and leave the soil to dry. Repeat the process as necessary but ensure that the soil dries in between each repetition.

In this method, the tepid water absorbs salts content from the soil through osmosis.

If the plant is severely impacted, you can counteract the harm sustained by using 1 gram of Osmcote 14-14-14 or Nutricote 13-13-13.

But, only use this procedure as the last option to treat them.

7. Potting and Re-potting

Although it may appear that selecting the right type and size of pot for your Hoya fungii is unimportant, it is.

You do not want waterlogged soil around your Hoya roots. Hence, avoid using a large pot as it takes longer for water to dry up.

Also do not get stuck to a smaller pot as it chokes your Hoya fungii’s roots. I use a 1-2 inches larger pot than its root ball.

While talking about the potting material, I generally prefer terracotta or coconut husk pot, especially a hanging one.

Nonetheless, you can use any of the materials as per your feasibility.

Re-potting Hoya Fungii

Hoya fungii loves to be slightly root bound, so you need not to re-pot the plant frequently.

I re-pot my Hoya fungii once in 2-3 years. Besides, I also consider re-potting them if there is root rot, high soil compaction, nutrients depletion, and extreme root-bound.

Generally, Hoya fungii show some tell-tell signs when it requires re-potting.

The symptoms include roots poking out of drainage holes, yellowing, limping, and drooping of foliage, smaller-sized newer leaves, and stunted growth.

Steps to Re-pot Hoya Fungii

  • Water your Hoya fungii thoroughly 8-10 hours before re-potting to enhance the root structure and help it adjust to a new environment.
  • Take a clean pot about 1-2 inches larger than the older pot.
  • If you use an older pot, soak them in a vinegar solution for about 30 minutes. Afterward, rinse and dry it.
  • Now, uproot the plant from the older pot.
  • Inspect for signs of root rot; if there are any, prune them, and dip the roots in a fungicide. Leave it in the air to dry.
  • Then, layer a few pebbles followed by soil. Place the plant at the center of the pot.
  • Next, fill the remaining space with the fresh potting mix.
  • Water the plant thoroughly and leave it in a bright space.

Note: The plant might limp and droop for a couple of days due to transplant shock. If you provide it with a favorable environment, it will revive naturally within a couple of days.

8. Rare Pruning

Pruning boosts bushier growth; if your plant is leggy, prune it as it enhances sideways growth.

Hoya fungii is not like other plants that require to be pruned regularly.

Similarly, you can consider pruning its dead, damaged, infested foliage or stems. You definitely do not want dead and damaged parts imbibing the plant’s energy.

Likewise, you can prune them to keep them a manageable size.

Consider pruning them once the flower stops blooming.

Pro Tip: Avoid pruning in the flowering season, which is spring and summer, as you might chop its buds.

The flowers of Hoya originate from peduncles protruding from the same stem junction every year, so you need to be cautious while pruning them.

Thus, I recommend not pruning flowers until they stop blooming completely.

Besides, pruning them before the blooming stops might delay and affect flowering next season.

Is Hoya Fungii Toxic?

It might chill your ears to hear that Hoya fungii are non-toxic to humans and pets.

Feel free to let your children and pets play around the plant without fear.

However, be careful of its milky sap as it might irritate. Besides that, there is nothing to be afraid of, Hoya fungii.

Hoya Fungii – All About the Growth Rate

The Hoya fungii is a beginner-friendly twining, compacted vining plant with semi-succulent characteristics. It grows moderate to fast depending on the environment where you grow them.

As a vining plant, it is generally ideal for growing in hanging baskets as its leaves create a beautiful cascading effect.

In its native environment, it climbs along with trees and over rocky surfaces.

It reaches a length of about 20 feet(6m) or more in the wild. However, you can expect it to grow almost 12 feet in an enclosed environment.

Hoya fungii is grown for its leaves that trail down with cascading effects and beautiful flowers.

Hoya Fungii Foliage and Flower

Its leaves are oval-shaped, velvety, fuzzy, and green with darker green veins and flecks. The leaves can reach about 9-16cm in length and gain about 6-9cm.

Besides, the Hoya fungii plant produces small flowers that grow in clusters forming a semi-spherical shape.

Its flower is similar to that of Hoya carnosa in pinkish-white patterns with a deep red center.

The flower has a sweet aroma during its flowering season in the warmer month, especially from October to April.

You can also expect to bloom them throughout spring and even in summer.

Propagation Method for Hoya Fungii

Multiplying your plants is always a good idea, whether let it be for you or gift someone. Besides, you can always create your Hoya edifice.

Propagating Hoya fungii is not a difficult task at all. You can quickly get new plants through cuttings.

But, if you are looking for more fun and adventurous method, you can harvest seeds and germinate them.

As all seeds are different, you might get plants with different traits than the mother plant.

The best time to propagate Hoya is in spring or summer when the plant is actively growing.

1. Propagating Hoya Fungii via Stem Cuttings

It is my favorite method of propagating Hoya fungii. I find this method relatively more straightforward, faster, convenient, and successful compared to others.

Here are the steps to follow for stem propagation of Hoya fungii.

  • Sterilize all of your instruments before propagation.
  • Also, ensure to take a sharp instrument that can give clean cuts lessening stress to plant.
  • Now, inspect for a healthy stem free from diseases and pest infestation.
  • Choose a slightly older and matured stem for best results rather than a new one.
  • Now, divide the stem strand into as many cuttings as you like. But, make sure that each cutting is 3-4 inches and has at least two nodes and 2-3 leaves. Also, make cuts 1 inch below the leaf node.
  • Leave the cuttings in the air for callous formation for a couple of hours.
  • At this point, you can use rooting hormones or cinnamon power to enhance rooting and prevent bacterial and fungal growth. But, the step is entirely optional.
  • Now, you can propagate the cuttings either in water or in soil.
  • Simply insert the cuttings in the soil such that one node is inside the soil. Water the plant thoroughly and leave it in a brightly lit space.
  • For water propagation, take a clean jar filled with water. Dip the cuttings in the water and watch the roots sprout.
  • Also, ensure to change the water in 4-5 days.

Generally, your cuttings will likely start producing roots within 4-6 weeks. You will have a well grown baby plant within 2-3 months.

2. Propagating Hoya via Seed Germination

The method is slightly complex compared to stem propagation.

It involves pollination of seeds and timely harvesting; hence you need more patience and effort to propagate Hoya fungii via seeds.

Pro growers generally use it to obtain hybridized species as all seeds bear different characteristics.

Here are the steps to propagate Hoya fungii via seed germination.

  • Leave your plants outdoors for a couple of days when it starts blooming. Its flower attracts pollinators like bees, butterflies, etc.
  • After successful pollination, the flower will bear seed pods, from where you can gather its seeds.
  • Otherwise, you can buy Hoya fungii seeds directly from commercial markets.
  • Take a seedling tray or any other shallow container and fill it with seed starter mix.
  • Layer some of the wet peat moss on top and place the seeds on top.
  • Spray water on top of the seeds. It helps prevent the flying away of seeds and seeds to peat moss.
  • Now, you can create a greenhouse effect for faster germination.
  • Otherwise, simply leave it in a warm and humid area and bright space.
  • You can see the seeds sprouting within a week.

Common Problems in Hoya Fungii

Like other house plants, Hoya is prone to common problems like pests and disease infestation.

Generally, these problems are the by-product of growing them in a poor environment.

Hence, maintaining a conducive environment helps protect your Hoyas from such issues.

1. Common Pests Infestation

Your beautiful Hoya fungii might sometimes catch common pests like mealybugs, aphids, and spider mites.

Immediately isolate your plant if you find any signs of infestation to prevent spread.

Besides, you might sometimes be troubled by red spiders, grasshoppers, slugs, snails, and rodents if you are growing your Hoyas fungii outdoors.

Mealybugs– These are small spa sucking insects that cover the plant with their waxy secretions.

If you see tiny white-cotton-like bumps, especially on the undersides of your leaves, that’s mealybug.

Mealybugs

Aphids– These are tiny grey or black-colored insects that covers leaves and stems. They cause stunted growth, curing, and wilting of foliage.

Besides, they secrete honeydew, which makes your plant hub to mold spores, leading to various types of fungal infections.

Spider Mites–  These tiny inspects occur on the underside of leaves and are responsible for discoloration, speckling, and white webbing on your Hoya foliage.

Treatment Measures

  • Knock off mealybugs by spraying a homemade mixture composed of 1 part rubbing alcohol, four parts water, and a few drops of dish wash soap.
  • Similarly, wipe off its foliage with cotton balls or a sponge soaked in diluted rubbing alcohol.
  • Another effective way is applying neem oilinsecticidal soaps, and horticultural oils to the entire plant.
  • A strong jet of water can toss off insects like spider mites.
  • Have a regular inspection of your plants for early diagnosis and treatment.
  • To prevent the spread to other plants, quarantine your Hoya fungii.

Preventive Measures

  • Check the plant for pest infestation before buying it.
  • You can use a commercial Aphid-free potting mix.
  • Avoid watering the plant when the soil is fully saturated.
  • Always use clean, sterilized instruments while pruning and propagating.

2. Horticultural Diseases

The top-notch enemy of Hoya fungii is fungal and bacterial diseases. As these diseases result from a poor environment, you can prevent them from occurring using the simple care tips stated above.

1. Bortyris Blight

Causative Agent- Botrytis cinerea

It is also called grey molds for its grey appearance. The species is notable for damaging buds, blooms, leaves, and bulbs.

First, it causes dark irregular brown patches on leaves, stems, and flowers, which, if left untreated, grow larger.

It turns the affected parts mushy in their final state, leading to the falling off the parts. Besides, abnormal growth and browning of flowers are also due to it.

2. Sooty Molds

Causative Agent – Saprophytic Fungal Organisms

Sooty molds are generally caused by pest infestation in your plant. Pests like aphids and scales produce a sticky substance known as honeydew that attracts sooty mold spores.

These molds hinder plant form from conducting photosynthesis, covering the entire leaf surface. Besides, it also causes wilting, drooping, and limping of leaves.

If the leaves of your Hoya fungii are covered with tiny black substance all over the surface, that’s sooty molds.

Note: The Sooty mold fungi are producing stalks (conidiophores) to launch their spores into the air.

3. Root Rot Diseases

Causative Agents- Phytophthora, Pythium, and Rhizoctonia spp.

Prolonged waterlogged soil or high soil temperature above 60°F might be vulnerable to your Hoyas as it might bring root rot.

Root rot in Hoya is accompanied by yellowing, drooping, and sudden wilting of foliage. Besides, the roots, stems, and leaves turn mushy and foul order comes out of the soil.

Treatment Measures

  • To avoid further spread, cut off affected parts using a clean, sanitized pruning instrument.
  • Soak a sponge in soap water and wipe off sooty molds.
  • Similarly, you can spray diluted seaweed fertilizer to treat sooty molds.
  • For root roots, it is ideal to report them in a fresh well-draining potting mix after pruning and applying fungicide.
  • To treat Botrytis Blight, spray fungicides containing Copper captain, mancozeb, sulfur, Chlorothalonil, maneb, and thiophanate methyl to the entire plant.

Preventive Measures

  • Do not overhead water and mist the leaves at night.
  • Isolate infested plants from other healthy plants.
  • Spray your Hoya with fungicide twice a year.
  • Always pair high humidity with good airflow to prevent fungal diseases.
  • Use clean, fresh well-draining potting mix.

Hoya Fungii Vs. Hoya Carnosa

It is quite right to get confused between Hoya fungii and Hoya carnosa.

Trust me; they look so similar that some vendors sell them under the same name.

The most identifiable feature of them is their flowers. You might find the flowers of Hoya fungii slightly larger than that of carnosa, but the difference is very insignificant.

So how can you identify Hoya fungii from Hoya carnosa?

Inspect their leaves. The leaf of Hoya fungii is broader and slightly round, whereas that of Carsona is narrow and slightly pointed at the tips.

Similarly, the veins of Hoya fungii are more prominent compared to Carnosa.

Conclusion

Hoya fungii will fill your space with its sweet aroma and splashy green tropical vibe.

Moreover, its non-toxic and low maintenance nature makes it one of the best plants for news and pet owners.

Just check in its light, water, nutrition, and humidity requirements, and it will blossom, spreading beauty to your space.
