    Keep soil consistently moist, never let it dry completely.

  • Temperature

    16–24 °C, dislikes cold drafts.

  • Humidity

    High (60%+) — thrives in bathrooms, kitchens, or near a humidifier.

Care difficulty

Moderate

Ferns appreciate a bit of extra attention, especially when it comes to humidity and consistent watering. With a regular care routine, they’re very rewarding and bring lasting greenery to any space. Even beginners can succeed if they keep the soil slightly moist and avoid very dry air.

    Ferns prefer bright but filtered light. Place them near a north or east-facing window, or a few meters from a south/west window with sheer curtains. Direct sun scorches fronds.

    • Asplenium (Bird’s Nest Ferns): tolerate slightly lower light.
    • Platycerium (Staghorn Fern): enjoys brighter filtered light.

    Keep the soil evenly moist, but not soggy. Use room-temperature water.

    • Check the top 2 cm of soil; if it feels slightly dry, water.
    • Rainwater is best as it prevents mineral buildup, but tap water is fine if it isn’t very hard. If your tap water is hard, flush the soil occasionally to wash out salts.
    • Reduce watering slightly in winter when growth slows.
    • For misting, use distilled or filtered water to avoid white spots on the fronds.

    These plants are native to humid forests. Aim for 60% humidity or higher.

    • Bathrooms and kitchens are excellent locations.
    • Pebble trays: Place the pot on a tray filled with water and pebbles. The pot should sit on the stones, not in the water — as the water evaporates, it raises humidity around the plant.
    • Humidifiers: The most reliable way to keep humidity steady.
    • Misting: Light misting can help temporarily, but it’s less effective than pebble trays or humidifiers and should not be the only method.

    Use a peat-free, well-draining potting mix rich in organic matter (a “houseplant” or “fern” mix).

    • Repot every 2 years, or when roots fill the pot.
    • Choose a pot with drainage holes.
    • For epiphytic ferns (e.g., Staghorn Fern), mounting on wood is also possible.

What it looks like: The tips or edges of fronds dry out, turn brown, and crumble.

Cause:
Air is too dry, or the plant is too close to a heat source.

Fix: Increase humidity with a humidifier or pebble tray, move away from radiators or vents.

Prevention: Place ferns in humid rooms (bathrooms/kitchens) and keep humidity above 60%.

What it looks like: Lower leaves fade from green to yellow before dying off.

Cause: Overwatering or poor drainage, sometimes low light.

Fix: Check that soil drains well and the pot has holes; allow the topsoil to dry slightly before watering again.

Prevention: Water consistently but avoid soggy soil. Use a light, airy potting mix.
