The Issue

Not many greenery challenge a person’s perseverance like ferns. One day they’re lush and vibrant; the next they look similar to dry brush left on a radiator. Fern fronds dry out at the slightest sign of low humidity, and after they turn brown, most think it’s game over.

This Hack

Put the plant inside a clear plastic bag – however leave it open as it requires some airflow – and position it in filtered yet ample light.

Indoor Plant Clinic: what causes a chalky crust on my potting mix?

The Explanation

This method forms a small greenhouse, trapping moisture near the plant. Consider it mimicking the tropical environment – the humid microclimate where ferns flourish. This won't water the plant for you, but it drastically slows down moisture loss and promotes delicate new fronds to open up.

The Experiment

I used this trick on a common fern that seemed beyond saving. After 10 days in its humid enclosure the potting medium was moist to the touch and small new shoots started emerging. Within a few weeks, the plant was noticeably thicker and greener.

This Verdict

This isn’t a miracle cure and some fronds might drop a few leaves along the way, but the bag trick can truly save a fern on the brink. At no expense, it’s one of the most successful revival techniques available.
