Anthurium Clarinervium Plant Care

Anthurium Clarinervium Plant Care



Using the right soil for an Anthurium clarinervium plant is super important. It’s as important, if not more, than everything else in this care guide.

The Anthurium clarinervium has very special soil requirements.

Loose and well-draining soil are a must-have. Anthurium clarinervium plants need serious and quick drainage. They’re prone to root rot and other conditions caused by too much water and moisture.

They also need acidic soil between 5.5 pH to 6.5 pH.

Orchid bark potting soil mixes are the best choice for these plants. We have the perfect potting soil mix recipe.

  • Douglas fir bark
  • perlite
  • sphagnum moss

All you have to do is mix the three ingredients. There should be more perlite and sphagnum moss than bark. The best ratio is 5 to 1.

The perlite retains water. Since you’re not using average potting soil, you need a material that holds onto some of the moisture.

Check the soil you’ve chosen for your Anthurium clarinervium plant. When you have the soil mix in the pot, pour water on it. Watch how the water drains through the soil and the plant pot. Make sure it’s draining as fast as it should be.



The right lighting can make or break your new plant. Anthurium clarinervium plants are picky and sensitive.

Keep your Anthurium clarinervium plant away from direct sunlight.

This means keeping it away from windows with direct sunlight coming through. Don’t sit it under any grow lights either.

Direct sunlight can burn and scorch your plant. It’s very sensitive to the sun and heat.

Filtered sunlight is the easiest option. A great way to gain filtered sunlight is to place the plant on an east-facing window. A north-facing window works as well.

Anthurium clarinervium plants need at least indirect light. They thrive with medium-light in brightness.



Watering an Anthurium clarinervium plant is a lot like watering other houseplants. You don’t want to over-water the plants but you don’t want to dehydrate it either.

Over-watering your plant can cause nasty root rot. Root rot rots the entirety of the roots until the plant dies. It’s important to make sure you’re using a self-draining pot.

Not giving your plant hydration starves it from that much needed water. It also stops it from going through photosynthesis.

During the growing season, you want the soil for the plant to be moist. Don’t water it until the first two layers of soil are dry.

You can test the moistness of your plant by pushing your finger through the soil. The soil should be dry up to your second knuckle.

Keep in mind, Anthurium clarinervium plants have exposed roots because they’re epiphyte plants. Exposed roots dry out faster than the roots of other plants.

You add the warmer seasons on top of that, your plants need watered more. So, you’ll be watering your Anthurium clarinervium plant about three times a week.

Outside of the growing season, you don’t need to water your plant as much. The soil retains water easier during the colder months.

Be careful, it’s easy to over-water your plant during the dormancy period. You’ll only need to water your plant twice a month at this point.



The right temperature for an Anthurium clarinervium depends on the time of year.

For the growing season, the temperature for the plant needs to be between 64F (18C) to 70F (21C). This is the best range for the best growth.

In the hottest of conditions, the plant can thrive in temperatures up to 85F (29C).

For the rest of the year, the plant can take temperatures down to 54F (12C). But it shouldn’t drop any more than this or your plant will freeze.



Anthurium clarinervium plants love high humidity. The humidity should be at least over 60%. But 80% is the best for this plant.

High humidity speeds up the plant’s growth. The leaves (and veins) will turn a brighter and green.

There are a couple of methods you can use to create high humidity for your plant.

The easiest way to create humidity is by using a humidifier in the same room. There’s no work or serious upkeep.

If you don’t want to spend money on a humidifier, we get it. They can get expensive. There is a less pricey option to try out.

For this method, you need pebbles and a tray. Fill the tray to the top with the pebbles. Then add water to the tray until it’s just under the pebbles. You don’t want the water to cover them.

Now, all you have to do is place your plant pot on top of the pebbles. As the water evaporates, it creates humidity. That humidity goes straight to your plant.



Fertilizing an Anthurium clarinervium plant varies on the season. These plants don’t need as much fertilizing as most other plants do.

When the growing season hits, you have to fertilize the plant about every two months. The rest of the year, you fertilize it once or twice altogether.

Always use half-strength indoor plant fertilizer. It should have a high amount of phosphorous in it. The phosphorous needs to be higher than all the other elements.

Mineral salt buildup can be an issue with an Anthurium clarinervium plant. To prevent mineral salt buildup, you need to flush your plant’s soil every three or four months.

Flushing the soil is pretty simple. You run water through the soil for about two or three minutes.

The running water is running through any built-up mineral salt from fertilizer.



You can propagate your Anthurium clarinervium plant in two different ways. You can do this through root division or even using stem cuttings.

Below we’ll go over both types of plant propagation.



When it comes to the growth of an Anthurium clarinervium plant, it all depends.

But on average, Anthurium plants grow between 15 and 25 inches.

As for the width of an Anthurium clarinervium plant, it can grow between 15 to 40 inches. Again, it depends on the species.

The leaves of these plants grow between five to 12 inches in length.



You should re-pot an Anthurium clarinervium during springtime.

And you shouldn’t re-pot your plant unless it’s too big for the pot it’s in. Or you’re trying to promote its’ growth.

For this plant, that’s about every two or three years.

Re-potting an Anthurium clarinervium is pretty easy. It’s like re-potting any other houseplant.


Anthurium Clarinervium Propagation Steps

The exciting aspect of propagating an Anthurium clarinervium is that you have options.

You can choose whatever option is easiest for you, root division or stem cuttings. We’re going to go over both methods and break them down.


Using Root Division

  1. First, you need to remove the Anthurium clarinervium plant from its’ pot. This is so you can get to the roots. Be careful as you pull your plant out of the soil. You don’t want to damage any roots and it’s easy to do.
  2. Rinse the soil from the roots. Be gentle during this process. Make sure the faucet or hose you’re using isn’t on full force.
  3. Now that you cleaned the roots, you can see them. It’s time to remove some of the roots to create a new Anthurium clarinervium plant. You need to pull some of the roots apart, from the original plant. Again, be very gentle while you do this.
  4. Let the divided roots sit out on a paper towel so they can dry. It should take about 12 to 24 hours.
  5. In the meantime, you should get your pot and soil ready. Try out our soil recipe above for your new plant. This way you know the soil is going to drain water quickly enough.
  6. Once the roots dry, it’s time to plant them in the pot. Plant them like you would any other plant. Dig a small hole in the soil that’s big enough for the roots. Place the roots in this hole and pat the soil around them so they’re almost fully immersed.
  7. All you do now is treat your new plant like you would any other Anthurium clarinervium plant. Water it when the first two layers or first two inches of the soil is dry. Make sure the plant is getting light but avoid direct sunlight.


Using Stem Cuttings

  1. Your first step is to get the stem cutting that’s going to produce your new Anthurium clarinervium. This is a tricky task because you have to have the right size of a stem cutting. And the easiest time to get the stem cutting is when you’re pruning the plant. The cutting needs to be two to four inches in length with at least two leaves. Make sure you’re cutting the stem cutting above a leaf node.
  2. Now you have to cure your stem cutting. Curing the cutting means that you’re allowing a callous end to form. Why is this important? Callous ends promote healthy growth. To cure the cutting, lay it out in a warm (but not hot) room. It needs to sit out for five to seven days to create a strong calloused end.
  3. As your stem cutting cures, you should get your soil and pot ready. Self-draining pots are one choice for Anthurium clarinerviums since they need quick drainage
  4. When your stem cutting dries, you can now plant it. Use your finger to make a small hole in the soil. It only needs to be big enough for the stem cutting to fit. Place the cutting in that hole.
  5. If your stem cutting can’t support itself, you can tie a straw to hold it up.
  6. Your last step is to treat it like you did your original Anthurium clarinervium plant. Place it in indirect sunlight and water your plant two to three times a week.


Anthurium varieties

There are tons of Anthuriums to choose from, outside of the Anthurium clarinervium species.

The species listed below are some of our all-time favorites.


Anthurium magnificum x crystallinum

This Anthurium variety happens to be our number one favorite. It’s one gorgeous plant with pinkish or reddish leaves. The plant stands out from most other houseplants.


Anthurium andreanum

Anthurium andreanum is another gorgeous plant with pink leaves. The leaves are heart-shaped and waxy. Plus, there’s a flower that comes through the leaves.


Anthurium scandens

This plant is a climbing vine plant. Unlike other species on this list, the leaves on an Anthurium scandens plant don’t grow very large. They’re small leaves, only growing up to five inches in length.


Anthurium veitchii

The Anthurium veitchii is also known as the “King Anthurium”. These are large plants. So, you need a big room to grow one of these. The leaves alone can grow up to four feet in length.


Anthurium magnificum

The Anthurium magnificum plant has large round leaves instead of elongated leaves. The white veins contrast against the dark green leaves.


Anthurium watermaliense

This plant is also known as the black Anthurium plant for obvious reasons. The leaves look black but they’re a deep purple in reality. The plant is perfect for anyone who loves dark things.


Anthurium warocqueanum

Since there’s a “King Anthurium”, there must be a “Queen Anthurium”. This species has super long velvety leaves. The Anthurium warocqueanum plant’s leaves can grow up to six feet tall.


Anthurium pachyneurium

The “Big Red Bird” Anthurium plant has leaves that grow up instead of down. These leaves have a zig-zag pattern around the edges. It also has a very short stem. In bright light, the plant turns red.


Common Problems with the Anthurium Clarinervium

Since the Anthurium clarinervium needs such high humidity, it’s a hot spot for all types of pests.

It’s important to always check your plant for plant pests no matter what. If you bring new plants into your home, check them before you do so.

One common pest problem comes from mealybugs. Mealybugs are strange and creepy looking bugs. They look like they’re covered in a cottony substance.

This outer coating holds onto moisture so the bugs don’t overheat or dehydrate.

They also excrete a waxy substance as they feed. This is the waste from feeding. It sticks to the plant as they move about.

According to the University of Maryland, the waxy excretion leads to black sooty mold.

Mealybugs feed on the sap of your Anthurium clarinervium plant. This means they steal the nutrients and water your plant needs to thrive.

Mealybugs cause a wide list of problems for your plant. This can include yellow or droopy leaves or even stunted growth.

In extreme cases, mealybugs can even kill your plant. This only happens in a plant with a long time infestation of the bug.

Another common pest for Anthurium clarinervium plants are spider mites. Spider mites are arachnids but they’re often confused as insects.

These eight-legged pests are oval-shaped. Most of them are translucent with two dark spots at their rear ends. The dark spots are where waste builds up from their feedings.

Like the mealybugs, spider mites steal the sap from your plant. This prevents your plant from going through photosynthesis so it can feed itself.

Since spider mites reproduce quickly, it doesn’t take long for an infestation to grow. The bigger the infestation, the worse the consequences for your plant.

The last common houseplant pest is the brown scale insect.

Brown scales lack armor or a protective covering to help them out. They’re oval-shaped and have long antennas. They’re also wingless.

Brown scales use their needle-sharp mouths to pierce through your Anthurium clarinervium plant. This strange mouth also allows them to suck up the sap. It’s as if their mouths are a straw.

With brown scales feeding on your plant, it’s going to lose its’ vibrant colors and healthy glow. Instead, the plant starts to droop and wilt.

It’s very rare for a plant to die from a brown scale infestation. The infestation has to get pretty bad to get to that point.

There are several natural ways to rid your Anthurium clarinervium plant of pests. Neem oil is always a great alternative to chemical pesticides.


Tips for an Unhappy Anthurium Clarinervium

Anthurium clarinervium plants are particular. You need to make the plant feel like it’s in a tropical jungle. You need to copy its’ natural habitat.

Otherwise, it can result in an unhappy plant. But that’s not the only factor that can create an unhappy plant. Either way, tips for a sick Anthurium clarinervium plant can come in handy.


Your Anthurium Clarinervium Plant’s Leaves are Turning Yellow

If your Anthurium clarinervium plant’s leaves are turning yellow, it’s stressed out. In most cases, this means your plant has moisture or water stress.

You’re either over-watering your plant or you’re under-watering it.

Check the soil of the plant. The soil shouldn’t be saturated. If you’re over-watering, you need to water the plant less.

Often, the first thing plant owners do in error when they see yellowing leaves is to think the plant needs more water.

But often, it is the exact opposite. Overwatering can cause less oxygen to get to the root system.

Basically, the oxygen pockets in the soil get replaced by water. The first parts of the plant to show signs of this are generally the leaves, which will begin to turn yellow.

The soil shouldn’t be bone dry either. Add some water and keep an eye on it. 

Now, f you are following the watering schedule in this guide, under-watering is less likely to be the reason your plant’s leaves are yellowing.

But if you are not, the leaves will yellow quickly. The soil needs to be consistently moist, not oversaturated, but lightly damp.


Your Anthurium Clarinervium Leaves Have Brown Tips

Anthurium clarinervium plants have brown tips if they aren’t receiving the humidity needed.

The thing to remember about tropical plants is that you need to mimic their natural habitats. Otherwise, they’re not going to thrive like you want them to.

One area to be accurate about is the high humidity for the Anthurium clarinervium plant.

As we stated earlier, the humidity for an Anthurium clarinervium plant needs to be at least 60%. But if you want optimal growth, the humidity should be around 80%.


Your Anthurium Clarinervium Plant’s Foliage is Dull

Anthurium clarinerviums with dull leaves and veins aren’t getting the light needed to be healthy.

Another major symptom of your plant lacking light includes slow or stunted growth.

When the plant isn’t getting the light it requires, it’s not able to go through the photosynthesis process. In other words, the Anthurium clarinervium plant isn’t able to create all the nutrition it needs.

Since you don’t want to use direct light on your plant, you have to be careful about fixing the situation.

Your best choice when it’s low on light is to put it in your window. But avoid your south or west-facing windows.

Stick to north or east-facing windows. It will get sunlight but not direct sunlight.


Anthurium Clarinervium Cultivars

There are several cultivars of the Anthurium around. You’ll find dozens for sale in garden centers and online. Even within the Anthurium Clarinervium you can see variety.

This is however generally caused by a hybrid activity, rather than a different variety in itself. These hybrids often result in slightly different variations in terms of leaf pattern, size and appearance.

If you prefer the leaves to be richer, darker and deeper green you can go for example for the Anthurium Clarinervium “Dark form”. 

Also known as the Anthurium Clarinervium Tarantula, the deeper green on the leaves leads to more prominent looking marking.

This mutation of the standard plant also results in more dramatic leaves. If possible, try to get your hand on one of these for a striking appearance in your house.

Look for the plant being marketed as “dark green” or “dark form” in order to land yourself one of these. If you have a standard version of the plant, you may not notice much difference in the beginning.

It is only when the plant matures that you will reap the benefits of your decision and be rewarded with deep green leaves. Would be great to get one of each and compare them as they grow!
