Salt/Mineral Accumulation

Excessive use of synthetic fertilizers or hard tap water causes salts to build up in the leaf tissue. As the plant transpires, these minerals concentrate at the leaf tips, causing localized cellular death (necrosis).

How to confirm: Check for a white, crusty residue on the surface of the potting medium or the edges of the pot.

Inconsistent Watering

Allowing the peat-based substrate to dry out completely between waterings stresses the plant's vascular system. This disruption in water transport prevents moisture from reaching the furthest extremities of the leaf tips.

How to confirm: Insert a finger into the soil to see if it is drying out much more rapidly than the plant's established routine allows.

Root Damage/Compaction

If the potting mix is too dense or has become depleted of oxygen, roots may begin to decay. Damaged roots cannot effectively transport water to the leaves, leading to tip desiccation.

Common

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

1 Gently remove the plant from its current pot to inspect the roots for any signs of mushy, dark, or foul-smelling decay.

2 Repot the Anthurium in a fresh, highly aerated medium like a mix of orchid bark and perlite to restore oxygen to the root zone.
