Maidenhair Fern
Adiantum
Maidenhair Ferns are known for delicate fan-shaped leaflets on dark, wiry stems. The soft, lace-like look is beautiful, but these ferns ask for steady humidity and moisture. If you can keep the environment consistent, they reward you with fine, airy foliage.

Full guide →Light
Place in bright, indirect light. North or east windows are ideal. Direct sun scorches the thin leaflets.
Water
Never let the soil dry out. Keep it consistently moist but not waterlogged. A self-watering pot can help. Always use a planter with drainage holes.
Soil
Use a peat-based mix that holds moisture yet drains well. Dense, soggy soil leads to root problems fast.
Humidity and Temperature
Humidity of 60% or higher is the make-or-break factor. Use a humidifier, pebble tray, or terrarium. Keep the fern away from heat vents and cold drafts.
Common Issues
Brown, crispy fronds usually mean dry air or underwatering. Yellow fronds can mean overwatering or hard water. If a dry spell crisps the top growth, keep the rhizome moist and wait for new fronds.
