Adiantum 'Rosy Maidenhair Fern' Care Sheet
General Information
The Rosy Maidenhair Fern (Adiantum) is a delicate, tropical fern known for its soft, lacy fronds with a pinkish hue when young. It thrives in humid conditions, making it ideal for terrariums, bathrooms, or shaded outdoor spaces in warm climates.
 
Care Requirements
🌿 Light
Prefers bright, indirect light.
Avoid direct sunlight, as it can scorch the delicate fronds.
Can tolerate low light but will grow more slowly.
💧 Watering
Keep the soil consistently moist, but not soggy.
Water when the top 1 cm of soil feels dry.
Use distilled, rainwater, or dechlorinated water to prevent leaf burn.
💦 Humidity
Requires high humidity (above 60%).
Ideal for terrariums or humid rooms (e.g., bathrooms).
If kept in open air, mist daily or place near a humidity tray.
🌡 Temperature
Thrives between 18°C – 26°C.
Avoid temperatures below 15°C, as it is sensitive to cold drafts.
🌱 Soil
Use a well-draining, rich, and airy mix:
Peat moss or coconut coir
Perlite or orchid bark for drainage
Leaf mold or compost for nutrients
🌿 Fertilizing
Feed with a diluted liquid fertilizer (half strength) every 4-6 weeks during spring and summer.
Avoid over-fertilizing, as it can damage the delicate roots.
✂️ Pruning & Maintenance
Remove yellow or brown fronds to encourage fresh growth.
If the plant dries out completely, cut it back to the soil and keep the soil moist – it may regrow.
🪴 Repotting
Repot every 1-2 years to refresh soil and provide more space.
Handle gently to avoid damaging delicate roots.
