The Problem

Not many plants test a person’s perseverance like ferns. At one moment they’re full of life; the next they look like dry brush left on a heater. Fern leaves crisp up at the first hint of low humidity, and once they turn brown, most assume it’s the end.

The Hack

Put the fern inside a transparent bag – but don’t seal it as it requires some airflow – and position it in filtered yet ample light.

This Explanation

This method creates a mini terrarium, capturing humidity near the plant. Consider it mimicking the rainforest atmosphere – the humid microclimate where ferns flourish. This won't water the plant for you, but it significantly reduces moisture loss and encourages delicate new fronds to open up.

This Experiment

I tried this trick on a Boston fern that looked beyond saving. Following a week and a half in its humid enclosure the potting medium was still damp and small new shoots started emerging. Within a few weeks, the plant was noticeably fuller and greener.

The Conclusion

This isn’t a miracle cure and some fronds might drop some fronds during the process, but the bag trick can truly save a fern on the brink. At no expense, it’s one of the most effective revival techniques out there.
