Salt or Fertilizer Buildup

Accumulation of mineral salts from tap water or excessive fertilizer can burn the sensitive leaf tips of Anthuriums. This causes localized tissue death at the furthest extremities of the leaf.

Very Common

How to confirm: Look for a white, crusty residue on the soil surface or the edges of the plastic pot.

Inconsistent Watering

Allowing the potting medium to dry out completely between waterings stresses the plant's vascular system, leading to tip necrosis. Anthuriums prefer a consistently moist, but never soggy, substrate.

Common

Root Rot (Overwatering)

Excessive moisture in the substrate leads to anaerobic conditions, damaging the roots and preventing them from delivering water to the leaf tips. This creates a paradox where the leaves look thirsty even though the soil is wet.

Common

How to confirm: Gently lift the plant from its pot to check if the roots are dark brown and slimy instead of firm and white.
