Anthurium Pedatoradiatum – How to Care?

Anthurium pedatoradiatum, also known as Anthurium fingers, is a terrestrial evergreen perennial plant. Unlike other epiphytic or hemiepiphytic (living on other plants or trees) Anthuriums, this one has its roots in the ground.

Except for other facts, the Anthurium Pedatoradiatum is unique for its leaves. These finger-like protrusions are attached to erect petioles and reveal a leaf that looks like a hand!

Most of the Anthuriums originated from the regions of Central and South America. The Anthurium Pedatoradiatum is native to Southern Mexico. Therefore, famed for its classy foliage, people grow this Anthurium as an indoor houseplant in northern America.

Anthuriums

Let us talk about the genus Anthurium.

Anthurium is the largest genus of the Aroid family, Araceae. Housing more than a thousand species of indoor and outdoor herbaceous plants. This genus includes the plants wildly grown for their flowers and leaves.

Most of the Anthurium species are popular because of their blooms, but the Anthurium Pedatoradiatum is praised for its stunning leaves. Due to its terrestrial nature, it is more of a self-heading plant. It only needs a support while propagating or repotting until the roots anchor themselves.

Anthurium Pedatoradiatum — Characteristics

Let us look at the features of the plant.

Height & Size

Anthurium Pedatoradiatum can reach a height of more than a meter. Although most of the epiphytic plants of the family can reach up to several meters. Being a grounded plant, this Anthurium is shorter than the others.

The stems are 2-3 cm thick. Leaf scars are about 2 cm wide. The projections on the leaves of Anthurium Pedatoradiatum can grow up to 20-30 cm in length. The whole leaf gets equally wide.

The height, size, and shape vary from plant to plant. There are hybrids of Anthurium Pedatoradiatum as well. Some of them are dwarf, and some tall. Some of them are broad, while some are slim. If you are a caring expert, you can achieve as many as 13 “fingers” on the leaves.

Leaves

The most fascinating character of the Anthurium Pedatoradiatum is its leaves. These leaves are the primary reason people love these plants. Because of the unique foliage, Anthurium Pedatoradiatum is primarily grown as an ornamental houseplant.

While the mature leaves show their thrilling finger-like projections, the immature ones are heart-shaped. The “fingers” project out when these young leaves get deep incisions while getting older.

You can see all the leaves in the above image. Newly grown leaves usually tend to curl up a little if you are a little offhand with watering.

Flowers

I do not know why I could not find any Anthurium Pedatoradiatum with blooms. There is not even a single picture on Google. However, the flowers in Anthurium Pedatoradiatum are narrow oval-shaped with pointed ends. A yellow-green spathe encloses the spadix of the flower.

The flowers in this Anthurium are 7-9 cm in length. They are not showy, and people usually cut them off to save the plant’s energy. The plant uses this energy to focus on the leaves.

Growth

Unlike other plants that become dormant in winter, Anthurium Pedatoradiatum is an ever-growing plant.

It maintains growth even in non-growing winter seasons. That is why it appreciates a monthly dose of balanced fertilizer. I will elaborate on it further as we go into the article.

Toxicity

Anthurium pedatoradiatum is highly toxic if ingested. It is because almost all Anthuriums contain calcium oxalate crystals in them and can cause pain, swelling, and numbness of the mouth if eaten.

They are noxious to pets and children. You must seek immediate medical help if someone has ingested these kinds of toxic plants. It is best to keep these plants away from pets and tiny humans.

With that said, let us jump straight into our main topic.

Anthurium Pedatoradiatum — How to Grow and Care

1. Lighting Conditions

Anthurium Pedatoradiatum thrives in bright indirect sunlight. It can also tolerate medium to sometimes low lighting conditions.

Do not expose your Anthurium Pedatoradiatum to direct sunlight. Direct sunlight can burn its beautiful foliage.

Unlike other Anthuriums, the Anthurium Pedatoradiatum is not so crazy regarding lights. It does not yearn for bright lighting conditions and can do pretty well in front of a Southwest facing window.

There it will get a good amount of diffused sunlight throughout the day. You can effortlessly find a perfect spot in your home for this green champ!

2. Temperature

In North America, the temperature rises as we go towards southern coastal areas. Therefore, the native plant zones are warm and humid.

In southern Mexico, the average temperature ranges from 53°F to 82°F (12°C to 28°C).

Therefore, if we want our Anthurium Pedatoradiatum to thrive, we must keep it in warm temperatures ranging from 65°F to 75°F.

Anthurium Pedatoradiatum adores warmth close to our usual room temperatures from 18°C to 25°C.

It is adaptable to different temperatures. Just make sure that it is not opened up to drastic changes in the temperature.

3. Humidity

Living close to the native coastal areas, this plant flourishes in higher humidity.

If we look at the above stats, we see a wide range of varying humidity levels. Therefore, you can keep your Anthurium Pedatoradiatum in anywhere between 50% to 70% moisture levels.

These humidity levels are easily achievable in household settings. However, if you live in relatively dry areas, you may need to pick up the humidifier.

Anthurium Pedatoradiatum also loves weekly misting. There are no textures or variegations on the leaves. Therefore, do not worry while misting from a spray bottle.

This plant will appreciate it if you place it somewhere in the bathroom or a kitchen. These places have more water vapors, and thus, higher moisture levels.

The tips on the leaves are slightly thinner and are sensitive to lack of humidity. The edges turn yellow or brown because of an unhealthy watering schedule or a shortage of humidity.

4. Potting Mix

As it comes from the Araceae family, the Anthurium Pedatoradiatum loves an aroid potting mix.

This mix should be chunky, well-draining, and full of nutrients.

Let us make one. We are going to make the whole blend in four equal parts.

  • For the first part, use a regular potting mix. Use an organic premium potting mix for better results.
  • For the second part, add sphagnum peat moss.
  • Add horticultural perlite or Lecca to fill up the third part.
  • Add orchid bark to fill up the rest. You can also use any other type of bark. Medium-sized chunks work best. You can also add in a few teaspoons of horticultural charcoal.

With that done, we have an excellent soil mix for our Anthurium Pedatoradiatum. The roots anchor perfectly with the barky mixture. It is a well-draining and well-aerated blend that prevents waterlogging and root rot.

5. Watering

The watering hinges on the above-given conditions. It particularly depends upon the conditions you are offering to the plant.

If your plant is getting low to medium light, it will not dry out quickly. In that case, you may have to wait for a whole week to water it again. The best way to check when the plant needs water is to feel the dampness of the soil.

If the top 2 inches of the soil feels dry to touch, then you can give it another shot of hydration. Try to look for the plants’ signals. Once you get an idea of how the plant behaves in different moisture levels, you can become a pro in watering.

With an arid and well-draining potting mix, the Anthurium Pedatoradiatum will only need water once a week.

Overwatering is the most common issue with Anthurium Pedatoradiatum. It is the main reason for roots to rot and for bacterial and fungal diseases. The overly watered plant is under stress and can attract sap-sucking pests.

Therefore, you should know when to stop watering your Anthurium Pedatoradiatum.

6. Fertilization

I would recommend giving your Anthurium Pedatoradiatum a well-balanced fertilizer every month. It wildly grows during spring, summer, and fall. Then you can notch up the feed on a bi-weekly basis.

Use the fertilizer in liquid form (diluted to 1/4th of its strength). Excess fertilizer can cause “leaf burns.” It causes plant to get worse than getting better.

7. Propagation

The best and most efficient way to propagate Anthurium Pedatoradiatum is through stem cuttings. Most epiphytes form aerial roots and are relatively easy to propagate. The Anthurium Pedatoradiatum being a terrestrial self-heading plant needs to be taken out of the pot.

  • You must make clean cuttings of the sprouts having nice and healthy rootlets.
  • Use sterilized instruments to cut off the shoots.
  • Leave a good amount of foliage on the mother plant to help it survive.
  • Be careful not to cut the node from where the new sprout forms.
  • Root the cuttings into your aroid potting mix.
  • Keep them well moisturized for a few days.

8. Repotting

I recommend repotting the Anthurium Pedatoradiatum during propagation. In this way, you can also make new babies of this rare Anthurium species.

Anthurium Pedatoradiatum does not require frequent repotting. It will ask you for a re-pot when you see the roots coming out of the drainage holes or getting out from the sides. Do not go for a big pot just slightly increase the pot size.

It would be best to re-pot your plant before the growing seasons.


Conclusion

On that note, now your mind is filled up with all the useful information that you need to care for your Anthurium Pedatoradiatum.

The Anthurium Pedatoradiatum is one of the most exotic plant species on this planet. It is mostly grown as an indoor delicacy. Its amazing foliage can swiftly become the center of attention for the people.
