Anthurium radicans is one of the popular Anthurium varieties on account of its lovely, glossy, blistered-looking, heart-shaped, dark-green leaves which are deeply veined and for its showy flowers with a maroon pinkish color.

Anthurium Malyi has been greatly used by gardeners to produce a lot of new hybrids with remarkable features, but these hybrids can only produce sterile flowers.

Anthurium radicans Care Indoors

Anthurium radicans blossoms in bright indirect light away from direct sunlight, average warmth of 16-27⁰C, humidity of 60-80% and consistently moist, rich, well-drained, aroids potting soil coupled with monthly feeding during the growing season.

Anthurium Malyi requires pruning to keep it neat and also minimize pest and disease infestations. Repotting is only needed when it outgrows its current pot. Keep reading for more on these growing conditions and how to achieve them.

Watering

Water Anthurium radicans liberally during the growing season and allow the top 1-2 inches of soil to dry out between waterings to keep soil consistently moist.

Cut down on watering in the cold season as growth is reduce to maintain the soil slightly moist but do not allow the soil to dry out completely.

Ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot and eventual death of the plant.

Light Requirements

Anthurium radicans grows best in bright indirect light away from direct sunlight as it can scorch the leaves. A curtain-filtered sunny window is perfect.

Anthurium Malyi will also grow under a grow light where the natural lighting is not adequate. Take a look at these full spectrum grow lights on Amazon.

Rotate the pot regularly to ensure that the plant receives light on all sides for uniform growth.

Temperature and Humidity

Anthurium radicans requires average warmth of 16-27⁰C to thrive. Keep it away from cold drafts to avoid sudden changes in temperature.

Anthurium Malyi thrives in high humidity of 60-80%. To elevate humidity, set the pot on a wet pebble tray or use a cool mist humidifier. Check out these techniques on how to increase humidity for houseplants.

Clean the leaves regularly by damp-wiping with a soft cloth to get rid of dust. Do not leave water drops on the leaves as it may cause fungal infestations.

Feeding

Feed Anthurium radicans every 4 weeks during the growing season with a balanced, liquid fertilizer. Do not feed it in the cold season as growth is minimal and feeding at this time can lead to fertilizer burn.

Regularly flush out accumulated salts from the soil by running a stream of water through the soil until the water comes out through the drainage hole. Allow it to run for a few minutes and repeat the process several times

Potting Soil

The best potting soil for Anthurium radicans should be rich in organic matter and free-draining to prevent it from getting soggy while providing the required nutrients. Most potting mixes designed for aroids are ideal for this plant.

Repotting

Repot Anthurium radicans every 2 years at the beginning of the growing season. Use a pot one-size larger and free-draining soil that is rich in organic matter.

Ascertain that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot disease. Check out these ceramic planters on Amazon.

Pruning

Pruning Anthurium radicans is easy. Remove yellow and dead leaves to maintain the plant neat and also discourage pest infestations. Cut the leaves at the base of the stem with a sharp sterlized knife or pair of scissors to avoid unnecessary injuries which can lead to disease infestations. Cut away any dead and wayward leaves to maintain the shape of the plant.

Propagation

Anthurium radicans can be propagated during the growing season from from splits by plant division.

How to propagate Anthurium radicans by plant division

Water the Anthurium radicans thoroughly at least 1 day before to make it easier to divide and also hasten establishment. A well hydrated plant suffers less shock and takes a shorter time to take root.

Take out the plant from its pot and carefully divide it into sections by pulling apart the roots. Ensure each section has adequate roots to hasten establishment.

Select a 6 or 8 inches pot and ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting.

Fill the pot with loose, free-draining potting mix and make a hole in the center of the pot. Ensure that the hole is slightly wider than the root base of the section.

Place the section in the previously made hole and lightly firm the soil around the base while taking care not to bury it too deep; maintain the section at the same soil level it was in the previous pot.

Water the soil thoroughly and place the set up in a well-lit, warm place until the new Anthurium radicans is well established after which you can begin routine care.

Anthurium radicans Problems

Anthurium radicans problems include brown leaf tips, yellow leaves, drooping leaves, brown leaf spots, pests and diseases among others. Read on for more on these problems, their remedies and solutions.

Diseases

Anthurium radicans is prone to root-rot disease which is more prevalent in soggy soil brought about by poorly drained soils. Maintain the soil moist but not soggy. Ensure that the pot has a drainage hole and that the soil is free-draining to avoid getting soggy soil.

Pests

The common pests in Anthurium radicans are spider mites, aphids and fungus gnats. Isolate the affected plant to prevent spread to other plants and treat it with neem oil to get rid of the pests as instructed by the manufacturer.

Drooping leaves and stems

There are four causes of drooping leaves and stems in Anthurium radicans. The first cause of drooping leaves is low humidity. To elevate humidity, set the pot on a wet pebble tray or use a cool mist humidifier.

The second cause of drooping leaves and stems in Anthurium Malyi is incorrect watering; either underwatering or overwatering. Keep the soil moist at all times during the growing season and never allow the soil ball to dry out completely. Learn more on how to water houseplants the correct way.

The third cause of drooping leaves and stems in Anthurium radicans is too high temperature due to exposure to direct sunlight. Protect the plant from direct sunlight by filtering the light with a sheer curtain.

The fourth cause of drooping leaves and stems in Anthurium Malyi is pests and diseases infestation. Inspect the plant and take control measures for these pests.

Brown leaf tips

Two reasons are responsible for brown leaf tips in Anthurium radicans. One reason for brown leaf tips is that the air is too dry. Set the pot on a wet pebble tray to raise humidity.

The second reason for brown leaf tips in Anthurium Malyi is soggy soil. Maintain the soil moist but not soggy by ensuring that the pot has a drainage hole and that the soil is free-draining (drains easily).

Yellow leaves

There are two causes of yellow leaves in Anthurium radicans. One cause of yellow leaves is soggy soil. Maintain the soil moist but not soggy by ensuring that the pot has a drainage hole and that the soil is free-draining.

The second cause of yellow leaves in Anthurium Malyi is cold drafts (cold air). Keep the plant away from cold drafts or place it away from windy doors and windows.

Brown leaf spots

The brown leaf spots are sunburn marks caused by exposure of Anthurium radicans to direct sunlight. Move the plant to a shaded place or use a curtain to filter the light.
