Frequently Asked Questions
Why does my Maidenhair Fern seem so much fussier than my other ferns?
It's genuinely more sensitive to water quality and humidity swings than tougher ferns like Boston or Holly Fern. Use distilled or room-temperature filtered water and keep humidity consistently high to avoid rapid frond browning.
My Maidenhair Fern's fronds all turned brown and crispy — is it dead?
Not necessarily — if the black wiry stems (rhizomes) are still firm and green at the base, cut back all the dead fronds, keep humidity high and soil consistently moist, and new fronds will often regrow within weeks.
