ow do we care for Anthurium Clarinervium? These delicate, beautiful aroid plants are their happiest in bright, filtered sunlight and adore moist, well-draining soil. They require good watering once the topsoil is dry, to be fertilized in the growing season, and kept in humid conditions of 60% or more.
I’ve certainly seen our fair share of beautiful foliage, from notches and holes to trailing vines, multicolored hues, and beautiful blooms.
And the Anthurium Clarinervium is one of the most exquisite of all, with beautiful yellowy-white veins seeping through the deeply lobed shaped-heart leaves and forming a stunning pattern along the edges.
In this guide, I’ll uncover the ultimate Anthurium Clarinervium care guide including how to grow and propagate them.
I’ll look at how to take care of anthurium plants, their requirements for temperature, water, fertilizing, indirect sunlight needs, and much, much more. So, without further ado, let’s begin.
Native to Chiapas, Mexico, the Anthurium Clarinervium, also known as Velvet Cardboard Anthurium, is an aroid that forms part of the Araneae species.
Along with the ever-so-popular group of plants like the Monstera, Alocasias, and Philodendron varieties.
These perennials thrive on rocky landscapes and in sun-flecked forests. Caring for these plants is similar to many other tropical plants, provided you give them the right soil, water, and light they need.
During winter and fall, these plants’ growth slows down, and they won’t require any fertilization. By adding fertilizers during these colder months, you could end up damaging your plant.
Its moisture requirements may remain the same as the warmer months; however, keep in mind that your watering habits should alter according to how dry your plants’ environment is during the colder months.
In addition, in wintertime, the plant should be kept away from any heaters, air conditioners, and strong drafts that could cause damage to your plant’s leaves.
Anthurium Clarinervium’s thrive in filtered, indirect light conditions but not direct sunlight. These plants love the shade, and any prolonged exposure to direct sunlight could potentially burn or scorch your plants’ beautiful foliage.
However, no exposure to any light can also affect your plant’s health.
Situate your plant away from windows with direct daylight shining through. The best place to put your Anthurium Clarinervium is in a room with bright light and humid conditions like your bathroom.
These plants are sensitive to the heat and sun, so a filtered, medium-light bright room is the best way to go to see your Anthurium Clarinervium thrive.
Standing in direct sunlight for an extended period of time might also be harmful to the growth of your plant.
Direct sunlight can scorch the leaves, turning them yellow or making them paler. Your plant could droop or begin to wilt from being stressed.
Anthurium Clarinervium does best in medium-bright, filtered light conditions. However, these plants cannot be without any light at all. You will be able to tell if your velvet cardboard plant isn’t getting enough light by the color of its foliage.
The bright, creamy-white-yellow veins may start to lose their vibrancy. You may begin to notice the plants’ growth has slowed down, or its stems have become leggy.
Velvet Cardboard Anthurium grows best in warm, moderate temperatures of 65ºF to 80ºF. This makes them perfect for most households. If you live in a slightly warmer or cooler place, these plants can tolerate a little leeway.
Contrarily, these plants can tolerate colder weather, but once temperatures drop below 55ºF, these plants may begin to show signs of stress, including wilting or yellowing leaves.
Similarly, anything higher than 86ºF, they’ll start to dry up faster.
Originating from the tropical rainforests of Mexico, the Velvet Cardboard Anthurium plants are accustomed to high humidity. These plants require a minimum of 60% humidity but thrive best in 80% humidity.
Although it’s unlikely that your home’s humidity will be sufficient, there are a few options to help your plant thrive.
You could try placing your plant in rooms that tend to have more moisture, such as the kitchen or a bathroom.
Alternatively, you could group your Anthurium Clarinervium with other plants. Together, plants release moisture into the air, causing their surroundings to become more humid.
Other options for increasing humidity include:
While Anthurium Clarinerviums are often mistaken for plants that are epiphytes (air plants), these plants are actually lithophytes. This means they grow naturally on bare rock or stone as mere support and have no appendage to the ground (they don’t need soil).
These plants grow best in soilless mediums such as bark, moss, orchid mix, or LECA balls. That being said, you can grow them in soil using a fast, well-draining potting mix. And to boost its growth, you can add chunky orchid bark.
Unlike other regular houseplants, these plants grow best on-air more than they do in soil. So, it’s important to ensure you have fast-draining soil which avoids putting them at risk of getting waterlogged.
Velvet Cardboard Anthuriums are picky when it comes to the right kind of lighting, humidity, and the type of growing medium it receives. But it’s fairly low maintenance when it comes to watering and fertilizing.
Anthuriums only require light watering once a week. Although, during the summer months, these plants may need watering up to twice a week, depending on if you’re living in a warmer climate.
As a rule of thumb, you should keep the soil moist during this growing season (spring and summer).
The best time to gauge whether it’s time to water your Anthurium Clarinervium is to check the top 2-inches of the soil. Stick your finger into the soil; if it feels dry then it’s time to water your plant.
Anthurium Clarinerviums don’t like being overwatered or waterlogged. Take a look at some symptoms that may appear if you’ve over or under watered your Velvet Cardboard Anthurium:
- Yellowing leaves with brown edges
- Little to no new growth
- A weak or rotten stem
- Browning edges on the leaf
- Stunted growth
Tip: The amount of light provided, and the season will directly govern the frequencies of watering. If your plant is kept in a darker room, it will require less water as opposed to a plant kept in brighter, sunnier locations.
The best time to prune your Anthurium Clarinervium is in spring or early summer, ideally before the growing season.
Pruning helps Anthuriums keep healthy, and it encourages new growth. Additionally, trimming any leggy stems, older foliage, or dead leaves may help maintain it.
It can also help the plant focus its energy on new growth instead of trying to fix deteriorating ones.
Velvet Cardboard Anthurium doesn’t require too much pruning but be sure to remove any dead or dying leaves.
To preserve as much energy-producing foliage, you can also remove any damaged or discolored leaves and as well as any dead or wilted flowers from the stem.
Fertilizing a Velvet Cardboard Anthurium varies for each season. These pants don’t require as much fertilizing as other plants.
During the growing seasons (spring and summer), you should feed it once every four to six weeks using a balanced formula such as an NPK ratio of 20-20-20.
You can use a houseplant fertilizer (organic or synthetic fertilizer) and dilute it to half strength. While in fall or wintertime, you won’t need to fertilize your Anthurium Clarinervium plants.
Because of its minimal feeding requirements, many beginner gardeners often find themselves tempted to give the plant extra fertilizer to help it grow.
Unfortunately, like overwatering plants, this is bad for your Velvet Cardboard Anthurium and could lead to detrimental effects.
You should aim to dust the leaves of your Velvet Cardboard Anthurium to keep it clean. While you won’t necessarily need to brush or wipe the leaves every day, if you’ve left them unattended for too long, in severe cases, your plants may struggle to photosynthesize.
You could spray or wipe the foliage down from time to time to keep the leaves hydrated and the dust levels down.
Be sure to wipe away dust every now and then using a damp cloth, while supporting the underside of the leaf with your other hand.
Once you’ve noticed your Anthurium Clarinervium roots have started filling the container or starting to circle its pot, it’s time to move it to a bigger pot.
You can expect to repot your Velvet Cardboard Anthurium every two to three years.
Here’s a step-by-step guide on how to repot Anthurium Clarinervium:
- First, remove the plant and root ball from its current container.
- Lightly dust or shake off any excess soil and untangle the roots.
- If you’re dividing the plant (propagating by division), this is where you’ll split off a few sections of the roots.
- Next, fill half the new pot with fresh potting mix.
- Place your plant inside its new container and fill the remaining space with the rest of the soil.
- Water thoroughly and resume watering once the top part of the soil has dried out.
There are three ways of propagating Anthurium Clarinervium plants, namely:
- Stem Cuttings
You can grow new plants from seed, however, this may be the most difficult, and it isn’t very efficient – it also is the longest of the three methods. Propagation by division and stem cuttings is considered the easiest.
For easy propagation, follow these steps to propagate by root division:
- Gently remove your Anthurium from its pot.
- Then shake off any excess soil or dirt and untangle the roots.
- Separate smaller offsets or stems, making sure each root has at least one or two leaves.
- Plant the new roots in a similar potting mix as the mother plant.
- And lastly, water the plant to settle the soil.
Follow these simple steps for successful propagation and learn how to grow Anthurium from stem cuttings:
- Use sterile scissors or a blade and cut 4 to 6-inches from a stem that already has aerial roots.
- Dust the cutting with a fungicide to help avoid any infection.
- Next, dip the end of the root with a rooting hormone.
- Then, use the same soil as the mother plant and plant your cutting into its own pot.
- Lastly, place your fresh cutting in a warm area with indirect, bright light.
Note: “Patience is a virtue.” Cuttings often wilt and take a few weeks to start to stand again.
Anthurium Clarinervium is highly resistant to pest infestations and diseases. However, because they are finicky when it comes to humidity and sensitive to overwatering, these environmental issues can provoke diseases and pests to appear.
Take a look at some of these common problems Anthurium Clarinervium may have and how to deal with each one.
Like many other plants, overwatering is the main culprit of root rot for Anthurium Clarinervium.
Root rot is a fungal disease that’s usually caused by the plant’s roots sitting in wet soil for too long and prevents the plant from absorbing any nutrients. Your plant’s roots will begin to turn mushy and black and eventually die back.
Although overwatering may be a common cause of root rot, there may be other causes, including a fungus or bacterial infection or inadequate drainage.
If you do happen to suspect your Anthurium Clarinervium has root rot, here is what you should do to save your plant baby:
- Firstly, gently remove the entire plant from the soil to inspect the roots and assess
- the damage.
- Next, rinse the root ball and use sterilized scissors to cut away any affected parts.
- Wash the roots thoroughly and dip the remaining healthy roots into a fungicide solution.
- Then, repot your plant into a pot with drainage holes and in fast-draining soil.
- Lastly, place your beloved Anthurium Clarinervium in a bright room with filtered light.
Mealybugs and other insects pose a risk to our precious Velvet Cardboard Anthurium plants. If you do get any pests, use gentle treatments that won’t damage the plant’s leaves.
As tropical plants, Anthurium Clarinervium thrives in dappled to medium light. Naturally, these plants reside under trees and on forest floors.
Anthurium Clarinervium drooping may be a sign of stress and that it’s not receiving adequate warmth, or the temperature is too low.
They may also be experiencing a water, lighting, or disease issue. Other factors could be if your plant is left near a heater making the air drier and causing it to experience low humidity.
Your Anthurium Clarinervium grows best in a humid environment. If humidity is an issue, you could try increasing the humidity around your plant.
Anthurium Clarinervium leaves turning yellow at a rapid rate is a sure sign the plant is feeling stressed. In most cases, it’s either a moisture or watering issue.
You could also check your plant’s soil; the soil shouldn’t be saturated or bone dry. Contrarily, it should not be soggy and wet.
If you notice your Velvet Cardboard Anthurium is developing brown spots on its leaves, this could be a sign they are not receiving the humidity they require.
Keep in mind that these are tropical plants, and you need to try your best to mimic their natural habitats and moisture levels, which is crucial to these plants looking and feeling their best.
As mentioned earlier, Anthurium Clarinervium plants require a minimum of 60% humidity and grow their best at 80% humidity. You could try up the humidity around your plant and purchase a humidity monitor.
A common pest problem amongst many plant babies is spider mites. These are arachnids and are often confused as insects.
These pests are oval-shaped, and most of them appear translucent with tiny dark spots at their rear ends. The dark spots that appear on the leaves are from the mite’s feedings.
Similar to mealybugs, spider mites devour the sap from your plant, thus, preventing your plant from photosynthesizing and feeling. And since these mites produce quickly, it doesn’t take long for an infestation to grow.
To prevent infestations of spider mites, you can keep the humidity levels up around your plant. Spider mites thrive on dry air, so moist air will deter them.
If your beloved Anthurium Clarinervium is suffering from a case of spider mites, you can treat it by:
- Spraying plant-based miticides: There are plenty of products to help deter and get rid of any pests. Some great natural remedies include rosemary spray, cinnamite, and neem oil.
- Prune & isolate: If you suspect your plant has a pest infestation, you should isolate your plant and prune away any visible webbings. Also, you should disinfect the area where your plant was before.
