Few plants challenge a person’s patience like ferns. At one moment they’re full of life; soon after they appear similar to dry brush left on a radiator. Fern fronds crisp up at the first hint of low humidity, and after they turn brown, many think it’s game over.

The 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.

This Theory

This method creates a small greenhouse, capturing humidity near the plant. Consider it mimicking the tropical environment – the moist mini-environment where ferns flourish. It doesn’t hydrate the plant for you, but it significantly reduces evaporation and encourages delicate new fronds to unfurl.

This Test

I used this technique on a Boston fern that seemed beyond saving. After 10 days in its humid enclosure the soil was moist to the touch and small new shoots began to appear. By the end of the month, the plant was visibly thicker and more vibrant.

This Verdict

This isn’t a instant solution and you may lose a few leaves along the way, but the bag trick can truly rescue a fern near death. For zero cost, it’s one of the most successful resuscitation methods available.
