Anthurium andraeanum Maine Brown Leaf Tips - Causes & Fixes

error

Low Humidity

Anthuriums are tropical plants that require high humidity levels, typically above 60%. When the air is too dry, the transpiration rate exceeds water uptake, causing the delicate leaf margins to desiccate and turn brown.

Very Common

How to confirm: Check if the tips are brittle and dry to the touch rather than soft or mushy.

1 Increase local humidity around the plant by using a pebble tray or a humidifier to maintain levels above 60%.

2 Mist the foliage regularly with a fine spray to provide immediate moisture to the leaf margins.

3 Monitor soil moisture levels to ensure the plant is not also experiencing drought stress, which can exacerbate tip burn.

Salt/Mineral Accumulation

Excessive buildup of fertilizers or minerals from tap water (like fluoride or chlorine) can burn the sensitive leaf extremities of Anthurium andraeanum. This creates a distinct brown necrotic zone at the tips.

Very Common

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

1 Flush the soil thoroughly with distilled or rainwater to leach out accumulated mineral salts and prevent further tip burn.

2 Switch to using filtered or demineralized water for all future watering to avoid introducing new fluoride or chlorine buildup.

3 Prune away the dead brown tips using sterilized shears to improve the plant's appearance and prevent the spread of necrosis.

Inconsistent Watering

Fluctuating moisture levels—allowing the medium to dry out completely before watering again—stresss the plant's vascular system. This prevents efficient water delivery to the furthest points of the leaf, resulting in tip necrosis.

Common

How to confirm: Monitor the soil moisture depth; if it is bone dry several inches below the surface, watering is irregular.

1 Stabilize the watering schedule by ensuring the soil remains consistently moist but not waterlogged, avoiding complete drying cycles.

3 Consider using a self-watering system or moisture-retaining amendments like perlite to help maintain steady hydration levels.

Root Rot (Early Stage)

While root rot often causes yellowing, the initial stage of oxygen deprivation due to overly compacted or waterlogged soil can manifest as browning tips. This happens when damaged roots can no longer transport water to the leaf margins.

Common

How to confirm: Gently lift the plant from its pot to check if the roots are dark, slimy, or have an unpleasant odor.

1 Inspect the roots for mushy, dark brown, or foul-smelling decay and trim away any damaged sections using sterilized shears.

2 Repot the plant in a highly aerated, well-draining medium to restore oxygen to the root zone; a mix of orchid bark and perlite is ideal.
