This Problem

Few greenery challenge a gardener's perseverance like ferns. One day they’re full of life; the next they look similar to dry brush forgotten on a radiator. Fern fronds crisp up at the slightest sign of dry air, and once they become discolored, many think it’s the end.

This Trick

Put the plant within a clear plastic bag – but leave it open as it still needs some airflow – and set it in bright but indirect light.

Houseplant Advice: what causes a white layer on my plant’s soil?

The Explanation

The bag forms a small greenhouse, capturing moisture around the plant. Consider it recreating the tropical environment – the humid microclimate where ferns thrive. This won't water the plant for you, but it drastically slows down moisture loss and promotes delicate young leaves to open up.

This Experiment

I used this trick on a common fern that seemed past recovery. After 10 days in its misty cocoon the soil was moist to the touch and small new shoots started emerging. By the end of the month, the plant was noticeably thicker and more vibrant.

The Conclusion

This isn’t a instant solution and you may lose a few leaves during the process, but the plastic bag method can genuinely save a fern near death. For zero cost, it’s among the top effective revival techniques out there.
