Lady fern · Athyrium filix-femina

Why are my Lady fern's fronds curling?

It is less common for Lady ferns to have curling leaves, but it usually points to a problem with moisture or temperature. Check the soil moisture level first to see if it is too dry.

Check these first

  1. Feel the soil to see if it is dry to the touch.
  2. Check if the plant is sitting near a heater or air vent.
  3. Look for signs of brown, crispy edges on the curled fronds.

Likely causes

  1. Underwatering

    Possible

    How to tell: The fronds will curl inward and feel dry or brittle to the touch. The soil will be completely dry and pulling away from the sides of the pot.

    What to do: Water the plant thoroughly until water runs out the drainage holes. Ensure the soil stays evenly moist by watering every 3 to 7 days.

  2. Heat Stress

    Possible

    How to tell: The fronds curl up to protect themselves from excessive heat or drying winds. This often happens if the plant is near a heater or a drafty window.

    What to do: Move the fern away from heat sources or cold drafts. Keep it in a cool, shaded area with stable temperatures.

When to worry

If the curling is accompanied by widespread browning, the plant is in distress. Minor curling on a few older fronds is often just part of the natural aging process.

Stopping it coming back

Maintain consistent soil moisture and keep the plant away from extreme temperature fluctuations.

Questions people ask

Can I save a fern that has dried out completely?
You can try soaking the pot in a basin of water for 30 minutes to rehydrate the root ball. If the roots are still alive, it may recover.
Is curling the same as wilting?
They are similar, but curling often happens before the plant fully collapses. It is a warning sign to adjust your watering routine.
