Water Anthurium radicans liberally during the growing season and allow the top 1-2 in. 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 Anthurium radicans.
Anthurium radicans requires an average warmth with a minimum of 160C to thrive. Keep the plant from cold draughts to avoid sudden changes in temperature.
Anthurium radicans thrive in humid conditions. To increase humidity, set the pot on a wet pebble tray or use a cool mist humidifier.
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.
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
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.

Select a 6 or 8 in. 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.
