Can I mist the fronds to stop the curling?

Misting helps temporarily, but it does not replace the need for consistent soil moisture. Focus on keeping the roots damp.

Will the curled fronds straighten out again?

Usually, once a frond has curled due to stress, it will not fully recover its shape. Focus on keeping the new growth healthy and hydrated.

Likely causes

Underwatering
Possible
How to tell: The fronds will curl inward and feel dry or crispy to the touch. The soil will be dry several inches down.
What to do: Water the plant thoroughly until water drains from the bottom of the pot. Ensure you water every 2 to 4 days to keep the soil consistently damp.
Heat stress
Possible
How to tell: The fronds curl up to protect themselves from excessive heat or dry air. This often happens if the plant is near a heater or a drafty window.
What to do: Move the fern away from any heat sources or vents. Ensure it is in a cooler, more humid location away from direct afternoon sun.

When to worry

If the curling is accompanied by browning and brittleness, the plant is in distress. It is normal for new fiddleheads to be curled as they unfurl, so do not confuse those with stressed fronds.

Stopping it coming back

Maintain a strict watering schedule to ensure the soil never dries out completely. Keep the plant in a stable, cool environment with high humidity.
