Brown Leaf Tips on anthurium

anthurium with brown leaf tips

What's Happening

Anthurium andraeanum evolved in tropical cloud forests with 70-90% ambient humidity. When indoor humidity drops below 50%, the large, thin leaves lose moisture faster than roots can supply it through vascular tissue. The leaf margins and tips—furthest from the water source—desiccate first, turning brown and crispy. Additionally, tap water salts (chlorine, fluoride, calcium) accumulate in leaf tissue over time, causing tip burn as salt concentration exceeds cellular tolerance levels.

How to Fix It

  1. 1

    Increase ambient humidity to 60-80% using humidifier (most reliable method)

  2. 2

    Create humidity tray: Fill saucer with pebbles and water; place pot on top (not touching water)

  3. 3

    Group plants together to create microclimate humidity dome effect

  4. 4

    Switch to distilled, rain, or filtered water to eliminate salt accumulation

  5. 5

    Trim brown tips with sterile scissors at an angle following natural leaf shape; do not cut into green tissue

  6. 6

    Mist foliage morning-only with room-temperature water to provide temporary humidity boost

How to Prevent It

Maintain consistent 60-80% humidity using humidifier or pebble trays. Use distilled or rainwater exclusively. Avoid placing near heating/cooling vents or drafty windows. Monitor with hygrometer and adjust seasonally.
