Why are my silver tree fern's leaf tips turning brown?

Brown tips on your silver tree fern usually mean the air is too dry or the water quality is poor. Check your humidity levels first, as these ferns crave moisture in the air.

Check these first

  1. Check the humidity level in the room.
  2. Feel the soil to see if it is drying out too fast.
  3. Smell the water you use for watering.

Likely causes

  1. Low humidity

    Most likely

    How to tell: The tips turn crispy and brown while the rest of the frond stays green. This happens often in heated homes during winter.

    What to do: Mist the fronds daily with distilled water or place the fern near a humidifier. You can also group it with other plants to create a microclimate.

  2. Mineral buildup

    Possible

    How to tell: The tips brown even when the soil is moist. This is often caused by salts or chlorine in tap water.

    What to do: Switch to using filtered, distilled, or rainwater for watering. Flush the soil thoroughly with clean water once a month to wash out accumulated salts.
