Light
Indoors or out, anthuriums grow best in bright, indirect light. Avoid direct sun, which can burn the leaves.
Soil
Anthuriums prefer a coarse, well-draining potting. An orchid mix with additional sand and peat moss mixed in, makes a perfect potting mix for anthuriums.
Water
The soil should be kept slightly moist and never allowed to dry out completely. Setting the pot in a tray of water-filled gravel will help the plant drain and also help keep humidity levels high. Allow the top of the soil to dry out to the touch before watering again.
