Climbing fern · Lygodium japonicum

Why are my Japanese climbing fern's tips turning brown?

Brown tips on your fern usually mean the air is too dry or the soil has dried out for too long. Check the humidity levels in your room first, as this plant loves moisture.

Check these first

  1. Touch the top inch of soil to see if it is dry.
  2. Check if the plant is sitting near a heater or air vent.
  3. Measure the humidity level in the room.

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 winter when heaters are running.

    What to do: Place your fern on a pebble tray filled with water to boost local humidity. You can also mist the foliage daily or run a humidifier nearby.

  2. Inconsistent Watering

    Most likely

    How to tell: The soil feels dry to the touch and the tips are brittle. The plant may also look slightly wilted.

    What to do: Water your fern every 3 to 7 days to keep the soil evenly moist. Never let the top inch of soil dry out completely.

When to worry

If the browning spreads rapidly to the base of the fronds, the plant is severely stressed. Minor tip browning is common in indoor environments.

Stopping it coming back

Keep the soil consistently moist and maintain humidity above 50 percent.
