Common Questions
Why did my Maidenhair Fern suddenly go completely crispy?
Maidenhair Fern is one of the fastest responders to dry air or dry soil of any common houseplant. Even one missed watering or a blast of dry air from a nearby vent can cause all the fronds to curl and crisp within a day. Cut the dead fronds back to the soil level and water thoroughly. If the roots are still firm and white, new fronds will emerge within a few weeks in a humid spot.
How do I keep the humidity high enough in a Canadian winter?
Forced-air heating in Ontario and Quebec homes drops indoor humidity to 20 to 30 percent from November through March, which is far too dry for a Maidenhair Fern. A small humidifier running nearby is the most effective solution. A pebble tray of water beneath the pot also helps. Misting the fronds directly is not recommended, as wet fronds in cool conditions can encourage fungal issues. Read our tips on keeping plants alive in winter for more detail on managing winter humidity.
Is Maidenhair Fern toxic to cats and dogs?
No. Adiantum ferns are confirmed non-toxic to cats and dogs by the ASPCA. Maidenhair Fern is safe for homes with pets and small children.
Can I grow it in a bathroom?
A bathroom with a window is often the best spot in a Canadian home for a Maidenhair Fern. The steam from showers raises humidity naturally, and a frosted or clear window provides enough bright indirect light. Avoid windowless bathrooms, where light is too low for sustained growth.
How often should I water it?
Check the soil every two to three days. Water as soon as the surface feels barely dry. Unlike most houseplants that forgive an extra day between waterings, Maidenhair Fern cannot tolerate even brief periods of dry soil without crisping. Use room-temperature water and pour it slowly until it drains from the bottom. Our indoor plant watering guide shows how to check soil moisture before watering.
