Care Essentials
Get to Know Your Button Fern
The #1 killer? Overwatering. Let the soil dry between waterings and your Button Fern will thrive.
Light
medium to bright indirect
Most comfortable in medium to bright indirect light. Avoid prolonged direct sun exposure.
💡 Grow lights: Thrives under artificial grow lights (LED or fluorescent, 10-12 hours/day). A great option if your space lacks natural light.
Watering
every 10-14 days
Let the soil dry out significantly between waterings — this plant is very sensitive to overwatering. When in doubt, wait another day.
Humidity & Temperature
Not fussy about humidity. Handles average indoor conditions without issue.
Standard room temperature (60-80°F / 15-27°C) is perfect. Avoid cold drafts and sudden temperature swings.
Soil
Standard well-draining potting mix works well. Add perlite for extra drainage if you tend to overwater.

Watering Issues (1 topics · 1 cases)
Is my Button Fern overwatered?
Button fern belongs to the Pellaea cliff-brake group, whose members prefer soil that is moist to slightly dry; wide fluctuations from bone dry to wet weaken the rhizome, and sustained overwatering can kill the plant by suffocating the roots and inviting rot

Is my Button Fern overwatered?
Button fern belongs to the Pellaea cliff-brake group, whose members prefer soil that is moist to slightly dry; wide fluctuations from bone dry to wet weaken the rhizome, and sustained overwatering can kill the plant by suffocating the roots and inviting rot
Cause
Button fern belongs to the Pellaea cliff-brake group, whose members prefer soil that is moist to slightly dry; wide fluctuations from bone dry to wet weaken the rhizome, and sustained overwatering can kill the plant by suffocating the roots and inviting rot.
Solutions
- Water the button fern thoroughly but let the soil dry slightly between waterings, avoiding the bone-dry-to-wet swings that weaken pellaea rhizomes.
- Grow the plant in a loose, humus-rich mix with ample drainage crocks in a large pot so excess water can escape and the fast-growing rhizome does not sit in saturated soil.
Prevention
Plant button fern in a fast-draining mix of equal parts coarse sand and leaf mold or peat moss, keep it in open shade during summer, and maintain stable conditions rather than alternating drought and soakings.
