Reviving Sun- or Frost-Burned Ferns

A fern moved from a greenhouse to direct sun shows extensive browning. The diagnosis: sunburn (or possibly frost damage). The remedy is straightforward.

Recovery Steps

1. Remove damaged fronds: Cut burnt fronds at the base to speed recovery.
2. Repot into a larger container: The fern is severely root-bound. Use fresh potting mix and a pot several sizes larger.
3. Provide appropriate light: Bright indirect light—no direct sun.
4. Water consistently: Keep evenly moist, not soggy.

With these steps, the fern should push new growth from the crown within weeks. The key is addressing both the immediate damage and the underlying pot-bound condition.
