Check these first

  1. Touch the top inch of soil to see if it is dry.
  2. Check the air humidity levels in your room.
  3. Inspect the fronds for signs of heat stress.

Likely causes

  1. Low humidity

    Most likely

    How to tell: The tips turn crisp and brown while the rest of the frond stays green. This happens often in homes with central heating or air conditioning.

    What to do: Mist your fern daily with a spray bottle or place it on a tray filled with pebbles and water. Keep the water level below the bottom of the pot to avoid root rot.

  2. Underwatering

    Most likely

    How to tell: The soil feels dry to the touch an inch down and the fronds look slightly brittle. Lady ferns need consistent moisture to stay lush.

    What to do: Water your fern thoroughly until water drains from the bottom of the pot every 3 to 7 days. Ensure the soil stays evenly moist but never soggy.
