Low Humidity

Anthuriums are tropical plants that require humidity levels above 60%. Dry air causes the leaf margins and tips to desiccate and turn brown, especially in temperature-controlled indoor environments.

Salt and Mineral Accumulation

The buildup of fertilizers, fluoride, or chlorine from tap water in the potting medium can cause chemical burn at the leaf extremities. Anthurium 'Arion' is particularly sensitive to high levels of salts in irrigation water.

Very Common

Inconsistent Watering

Allowing the substrate to dry out completely between waterings stresses the plant, leading to tissue death at the tips. This cycle disrupts the plant's ability to maintain turgor pressure in the delicate leaf margins.

Root Rot (Early Stage)

Overwatering leads to anaerobic conditions that damage fine feeder roots. As these roots die, they can no longer transport water to the leaf tips, causing them to turn brown even though the soil is wet.

Common

How to confirm: Gently lift the plant from its pot to check if the roots are dark, slimy, or smelling of decay.

1 Immediately inspect the roots for mushy, dark, or foul-smelling decay and trim away any damaged sections using sterilized tools.

2 Repot the plant in a fresh, highly aerated medium like a mix containing perlite or orchid bark to prevent future anaerobic conditions.
