Will Frost-Damaged Fern Fronds Recover?

After a light frost, a fern's fronds turn dark green (not brown/black). The base and roots remain healthy. The verdict: those dark green fronds will not recover. They'll eventually turn necrotic and fall off, potentially inviting disease.

Recommended Action

• Remove all dark green/damaged fronds at the base now.
• Keep the plant protected from further frost.
• Maintain consistent moisture—don't let it dry out.

Outlook

Because the crown and roots are intact, full recovery is expected. New fronds will emerge once conditions are favorable. The ⅓ of fronds that remain healthy will sustain the plant until new growth appears.
