Will the curled leaves uncurl?

Usually, once a frond has curled due to dehydration, it will not fully uncurl. Focus on keeping the new growth healthy and hydrated.

If you feel your skin getting dry or see other plants struggling, your home likely lacks the humidity this fern needs. Try grouping it with other plants to create a microclimate.

Check these first

Check the humidity levels in the room.
Look for crispy edges on the fronds.

Likely causes

Low humidity
Possible
How to tell: The edges of the fronds will curl inward and may feel crispy to the touch. This happens when the air in your home is too dry.
What to do: Place the fern on a pebble tray filled with water to increase local humidity. You can also mist the plant daily or use a humidifier nearby.
Underwatering
Possible
How to tell: The entire frond may droop and curl as the plant loses turgor pressure. The soil will feel dry and pull away from the edges of the pot.
What to do: Water the plant thoroughly until water runs out of the drainage holes. Maintain a schedule of watering every 3 to 7 days to keep the soil consistently moist.

When to worry

Stopping it coming back

Keep the plant away from heating vents or drafty windows. Use a humidity tray to maintain a steady environment.
