Frosty Fern Care
A striking, low-growing plant known for its soft, feathery green foliage tipped with silvery-white “frost.”
Its delicate appearance makes it a favorite for terrariums. While beautiful, it thrives in high humidity, consistent moisture, and gentle, indirect light, making it a plant best suited for attentive caregivers.
Light
Bright indirect light; avoid direct sun.
Watering
Keep soil consistently moist, never dry. Water when the top ¼ inch is just barely dry.
Humidity
Needs high humidity (60–80%); great for terrariums. Avoid direct misting.
Temperature
60–75°F (16–24°C); protect from drafts.
Soil
Light, moisture-retentive mix (peaty mix with a little perlite).
Fertilizing
Feed monthly during spring and summer with a balanced liquid fertilizer.
Repotting
Repot only when roots fill the pot—usually every 1–2 years—and move up just one pot size, keeping the soil evenly moist during the transition.
Pruning & Cleaning
Trim brown or leggy tips to keep it full.
Pet Safety
Non-toxic to cats and dogs, making them a pet-friendly plant.
Common Problems
Browning tips from low humidity, yellowing from overwatering, leggy growth from low light, and occasional soil mold in overly damp conditions.
Common Pests
Mostly fungus gnats from too damp soil.
Fun Fact
Frosty ferns aren’t true ferns—they’re actually a type of ancient clubmoss that reproduces with spores, making them closer relatives of mosses than modern ferns.
