The Ultimate Guide to King Anthurium Care

I bought the magnificent King Anthurium plant just a year ago, and believe me; it does not need very royal care despite the name.

This magnificent evergreen plant can grow quite large with different flowers and deep green colored leaves up to 6.6 feet with its maturity.

The King Anthurium plant, which has a striking appearance and average size, can also be grown indoors or in greenhouses in a hanging pot.

Despite its exotic look, I can assure you that King Anthurium is minimal maintenance and very easy to care for.

The ideal way to care for King Anthurium is to maintain the humidity high above 60%, the temperature in the range between 59°F and 79°F, avoid overwatering since the plant loves moist soil, fertilizing it every 6 – 8 weeks on average, and pruning it regularly.

If you are growing or planning to grow the King Anthurium, then you have come to the right place. I can share some wisdom on caring for the plant since I have been growing it for a while.

So without further ado, let’s check out the ultimate guide to King Anthurium care.

Ultimate Guide to King Anthurium Care

King Anthurium can be grown both inside or outdoors. You need to follow specific care tips to keep this plant healthy wherever you decide to produce it.

1. Watering Requirements

In general, the King Anthurium does not need to be watered regularly. I wet my King Anthurium only once a week.

However, the watering condition also depends on the type of soil and growing condition that you pick.

Growing your plant in a chunky soil mix and an arid environment will demand considerably more regular watering.

Similarly, you may need to water your plant less frequently if you grow it in a humid environment.

Pro Tip: I suggest you inspect the topsoil for dryness before watering your King Anthurium. If the top 2 inches of the soil are still moist, wait another two or three days before watering it.

Thus, this will assist you in avoiding overwatering, which would otherwise have a detrimental effect on your plant’s long-term health.

2. Ideal Temperature and Humidity

Anthurium Veitchii, a heat-loving tropical plant, thrives in cooler surroundings, and these pendulous plants like temperatures between 59 and 79 degrees Fahrenheit (15 and 26 degrees Celsius).

The plant is unable to withstand the cold. Therefore, if the temperature drops below 59 degrees Fahrenheit, it is recommended that you bring it inside to protect it from the cold damage.

Pro Tip: It is a good idea to put foam plastic under the pot if it’s on a chilly window during the winter.

Similarly, it needs high humidity over 60% and enough airflow. For this, you can also put your Anthurium Veitchii near other plants.

Also, installing a humidifier or utilizing a pebble water tray are other options for controlling humidity.

As a result, your Veitchii will flourish at its best throughout the cooler months.

3. Soil Mix for King Anthurium

King Anthurium does not require soil to grow. Since it is an epiphytic plant, it may also grow on the branches of other plants or trees with ease.

Rain, wind, and debris, such as leaf litter on tree branches, provide nutrients in this scenario.

However, if you want to cultivate the plant in your yard or a pot indoors, you’ll need nutrient-dense, well-draining soil.

You must ensure that your soil has a high drainage capacity as roots can decay if soil holds a lot of moisture.

So, you can enhance the drainage capacity by a potting mix that includes perlite or orchid bark. They aid in the development of the roots by providing favorable circumstances.

Likewise, terracotta pots are the finest choice for King Anthurium because they absorb excess moisture and prevent rotting of the roots.

Therefore, if you opt to plant Anthurium Veitchii on the ground, you won’t have to bother about draining because it will occur naturally.

4. Fertilizer Requirements

These plants develop as epiphytes on other trees and plants, extracting nutrients from them. But, of course, when you’re growing it in pots inside, the soil will be the only source of nutrients for your King Anthurium.

Thus, make sure to fertilize often to keep your plant happy and healthy.

I would recommend you fertilize your plant from March until late September when it is actively growing. And allow the plant to rest throughout the winter months, just as it does in nature.

The ideal fertilizer has all essential elements, such as phosphorus, potassium, and nitrogen, with an NPK value of 9-6.

Also, if you don’t fertilize your King Anthurium correctly, it will have smaller leaves than usual and won’t bloom.

Likewise, depending on the type of fertilizer you use, the frequency with which you fertilize your plant varies.

Having said that, some fertilizers might require more frequent application while others need to be applied every 6 – 8 weeks.

Therefore, switch to a high-quality orchid fertilizer if you want a better outcome and more blooms.

5. Sunlight and Ideal Location

It would be best if you never grew your King Anthurium in the direct sunlight, be it indoors or outdoors.

Exposing your plant to harsh rays will cause the plant leaves to burn. And who wants to ruin the beauty of their favorite plant in this way, right?

However, this also does not imply that you must maintain your plant in complete darkness.

Remember that this plant requires 70 – 85 percent of daily indirect or filtered light exposure for proper growth.

Likewise, if you’re growing it outside, it’s ideal for planting it in a somewhat shaded area.

On the other hand, to protect it from direct sun rays, place it approximately 6 – 8 feet away from a west or south window indoors. Filtered light from behind a curtain can also be effective.

As a result, hanging pots are an excellent choice for your King Anthurium.

6. Flower of King Anthurium

The inflorescences of the King Anthurium are its most distinctive feature and source of uniqueness. In addition, the blossoms of King Anthurium are among the world’s most long-lasting.

The inflorescence of King Anthurium is fashioned like an arrow, and with cream or pinkish colored spadix, the flower spike is leathery and greenish-white.

As the flower is long-lasting, this also implies that glossy color might remain for months after you have brought it from the nursery.

However, if your Anthurium isn’t blossoming while seeming healthy, the situation might get irritating. This might be due to a variety of factors.

So, if you want your King Anthurium to blossom, you’ll need to pay attention to various elements, including lighting, potting mix, temperature watering, and so on.

Even though King Anthuriums may thrive in low-light environments, if you don’t give your plant adequate light, it won’t blossom. So, place your plant in a spot where it will receive brilliant indirect sunlight.

7. Container Requirements

The pots or container requirements of King Anthurium usually depend on the age of the plant.

The majority of King Anthuriums are sold when they are young. You can get this plant from a nursery in plastic pots.

Unless your plant matures, you may keep it in plastic pots or terracotta containers.

However, you must ensure that these containers have enough drainage holes as your plant’s roots will decay if your pot doesn’t have drainage holes.

So, you’ll need to transplant the plant to a new pot after it’s matured.

The ideal containers for King Anthurium are hanging pots because the ceilings are generally in the appropriate hue, and they get adequate indirect light while kept in a bright space.

Also, you shouldn’t put your King Anthurium on the ground because it has huge leaves that can grow to be over 2 feet long. This will thus need ample space to unravel.

Hence, planting King Anthurium in the ground pot will make the leaves bend and, in some cases, even tear. Also, they’ll never be able to recuperate from the harm.

Therefore, to keep your King Anthurium healthy and happy, choose an orchid hanging basket. You can get one in pots and petals.

8. Diseases in King Anthurium

King Anthurium is susceptible to diseases such as pythium, bacterial blight, and bacterial wilt.

You need to immediately isolate your King Anthurium from other plants as soon as you realize that it has been infected by one of these.

The bacterial infection might induce due to excessive leaf damage or because it was unhygienically pruned.

Also, consider properly removing any diseased leaves to prevent infection from spreading.

This bacteria will, hence, limit the commercial production of your plant. And as a result, you must diagnose and treat these diseases as soon as possible.

So, below are the possible diseases, their symptoms, and their solution.

9. Pest Infestations

Talking about pests, you need to always keep an eye out for infections on the underside of the leaves. Pests are a constant problem in King Anthurium, especially when you choose to grow them outdoors.

The most common pests include thrips, spider mites, whiteflies, and mealybugs. Likewise, this plant could also attract aphids and scale insects.

You’ll be able to tell whether these insects have harmed your plant notice brown or yellow patches on plant leaves.

When these pests attack your King Anthurium, your plant will fade and stop producing new growth as a result.

So, it is crucial to learn the symptoms and deal with them as soon as possible.

Thus, to deal with these pests and keep your King Anthuriums healthy, you can use the following.

  • Water and soap
  • Neem oil
  • Spraying water
  • Rubbing alcohol

So, here’s a quick view of the common types of pests, their symptoms, and possible solution

9. Propagation of the Plant

There are two options to propagate the King Anthurium plant: stem cutting and division.

Cuttings can be used to propagate Anthurium Veithii; however, a division is likely to be the most effective method.

So, let’s look at both methods in more detail.

Propagating King Anthurium Through Stem Cutting

Here’s how you can propagate your King Anthurium from stem cuttings using our step-by-step instructions.

  • Finding a portion of the stem with at least two growth nodes is the first step. It will be even better if your nodes possess aerial roots as the propagation will be sped up.
  • The next step is to use the sterilized blades to cut a portion (about 1 inch) of the stem.
  • Fill the plastic containers with perlite or sphagnum moss and insert the stem cutting. Make sure that your plastic pot has enough drainage holes.
  • Place the pot in bright, indirect light in a warm environment.

Propagating King Anthurium Through Plant Division

The division approach is significantly faster than the stem cutting method because you already have a fully developed or semi-grown plant.

Thus, there will be no danger of it not developing.

  • First, remove the plant from its container. You must check the plants once they have been removed from the container.
  • Remove any excess dirt and then disentangle the roots.
  • Now is the time to select a healthy-looking stem and trace its roots. This is the point at which you will detach the smaller plant from the mother plant.
  • Again, to separate the root ball, use a sharp instrument such as a knife.
  • Finally, once you have split the section, place both plants in their respective pots and fill them with soil.

10. Repotting King Anthurium

The spring or summer season is considered to be the best time to repot Anthurium Veitchii. Your plant is actively developing at this period.

Typically, King Anthurium plants are slow growers as it develops a new leaf every three months. And, when the plant is actively developing during these seasons, it will need to be moved to a bigger container.

Hence, you should repot your King Anthurium if the roots start to grow out of the drainage holes in the pot.

The most critical part of securely repotting your plant is choosing the correct container. So, when repotting your Anthurium Veitchii, pick a container that is one size larger than the one it is now in.

Also, King Anthurium despises being submerged in water. However, ironically, it enjoys wet environments as well.

This means you’ll need to pick containers that can hold adequate water while still allowing moisture to escape.

Therefore, pots composed of porous materials such as terracotta and clay are ideal choices. And, of course, don’t forget about drainage holes.

11. Grooming and Pruning

The leaves of the King Anthurium are beautiful and need to be pruned and groomed on a regular basis. Although it is a slow-growing plant, you should prune it on a regular basis to remove older and unhealthy leaves.

You may trim your plant at any time, but it’s best to do it before the growing season begins.

To keep steams from drooping, remove older, dead, or diseased leaves during this operation.

Similarly, you also need to remember that the veins and midrib of King Anthurium leaves may accumulate a lot of dust. So, for cleaning the dust, don’t use any leaf shine products.

Instead, consider wiping both the front and back with a wet cloth.

So, there are a few things you need to be mindful of while pruning and grooming King Anthurium.

  • You need to always consider wearing gloves in the process as the plant might irritate your skin. And, also you will be using sharp knives or sheers, so taking extra precautions will eliminate small possible cuts or wounds.
  • Also, the King Anthurium is prone to leaf bacteria which can harm your plant. So, don’t forget to disinfect your knives and sheers before using them.
  • King Anthurium’s steam is relatively strong. So, to avoid damaging the steam, you should always use cutting tools rather than ripping them out with your hands.

Conclusion

King Anthurium is a magnificent addition to your house. While it might be finicky, you can rest assured, for it will give your room or garden an elegant if adequately cared for look.

In addition, it’s also a plant that requires very little upkeep.

Watering is simple after you’ve got the plant in the appropriate soil and the right spot. The plant also doesn’t need a lot of fertilizer, which means you only have to fertilize it once every three to four months.

Likewise, hanging pots are the finest container for this, and of course, don’t forget to include drainage holes. Also, keep in mind that King Anthurium prefers strong indirect sunshine.

You can plant your King Anthirum anywhere, be it in your living room or your garden.

This guide will help you keep your King Anthurium healthy and happy, and hence you can enjoy its long-lasting beauty for years to come.
