Maidenhair Fern (Adiantum raddianum), 4-Inch Pot

Maidenhair fern (Adiantum raddianum) carries tiny fan-shaped green leaflets on fine dark stems, creating an airy, lace-like silhouette. Its delicate look rewards a consistent watering routine and a spot away from dry drafts. Each live plant varies in fullness and frond length.

Points of interest and size

• One live maidenhair fern in a 4-inch nursery grow pot.

Care guide

• Light: Bright filtered to medium indirect light. Avoid strong direct sun, which can scorch the delicate leaflets.
• Water: Check the mix often, especially in a small pot. Keep it consistently lightly moist but never soggy; water when the surface is just beginning to dry, drain excess, and do not let the root ball dry completely.
• Soil: Use an airy, moisture-retentive fern or houseplant mix in a pot with drainage holes. Ready to repot? Shop our Rich Houseplant Soil Blend, hand-blended in small batches and sold separately. Maintain an airy texture while retaining enough moisture for this fern.
• Humidity and temperature: Moderate to high humidity helps prevent crisp fronds. A humidifier or a naturally humid, bright room is more dependable than misting alone. Keep away from hot dry vents and cold drafts; no exact 80% humidity target is required.
• Feeding: During active spring and summer growth, apply a balanced slow-release houseplant fertilizer sparingly, following its label directions. Ready to feed? Shop our 2 oz Slow-Release Fertilizer for Houseplants & Succulents, sold separately. Reduce or pause feeding in winter, and skip feeding while growth is paused or during extreme heat or cold.
• Pruning: Trim fully brown fronds close to the base with clean scissors. If it dries out and fronds brown, restore consistent moisture and watch for new growth.
• Repotting: When roots crowd the pot, move up one size in fresh airy mix, without burying the crown deeper.
• Propagation: Established clumps may be divided carefully during repotting; spores are a slower, more advanced method.
