Signs of Overwatering
Blackened, mushy fronds at the base and soil that smells sour mean the roots are sitting too wet.
Signs of Underwatering
The small, round, button-shaped leaflets turn brown and crispy, though this fern recovers reasonably well if caught early.
Adjusting for the Seasons
One of the more drought- and dry-air-tolerant ferns, making it a reasonable pick for less humid rooms where maidenhair or staghorn fern would struggle.
Pro Tip
The round, coin-like leaflets make this an easy fern to distinguish from lacier varieties at a glance, and its relative toughness makes it a good starter fern for someone who has struggled with fussier species.
