Plant care guide - Ferns
Ferns are among the oldest plants on Earth, known for their soft, feathery fronds and timeless appeal. Though they can be a little demanding, they thrive beautifully once their needs are understood. The secret lies in consistent moisture, steady humidity, and gentle light that echoes their natural forest homes.

Detaillierte Pflegehinweise
Lichtbedarf
Ferns prefer bright but filtered light; direct sun can scorch fronds.
- Place near a north- or east-facing window.
- If the window faces south or west, place the plant a few metres back or use sheer curtains.
- Note: Bird’s nest ferns (Asplenium) tolerate slightly lower light; staghorn ferns (Platycerium) like brighter filtered light.
- Do not place in direct sun.
Gießen
Keep the soil evenly moist, but not soggy, using room-temperature water.
- Check the top 2 centimetres of soil; if it feels slightly dry, water.
- Prefer rainwater to prevent mineral buildup (tap water is fine if it is not very hard).
- If your tap water is hard, flush the soil occasionally to wash out salts.
- Reduce watering slightly in winter when growth slows
- If you mist, use distilled or filtered water to avoid white spots on fronds.
- Do not let the soil become waterlogged.
Luftfeuchtigkeit & Temperatur
Ferns are forest plants: they love high humidity and do best in a stable range of 16 to 24 degrees Celsius, away from drafts.
- Aim for 60 percent humidity or higher.
- Put ferns in bathrooms or kitchens if the light is suitable.
- Use a humidifier for the most reliable results.
- Use a pebble tray: place the pot on stones above the waterline so the pot is not sitting in water.
- Keep temperatures within 16 to 24 degrees Celsius.
- Do not rely on misting as your only humidity method (it is temporary and less effective).
- Do not place near drafts from windows or air conditioners.
- Do not expose ferns to frost or extreme heat.
Düngung
In spring and summer, feed with a diluted balanced liquid fertilizer every 4 to 6 weeks; pause in autumn and winter.
- Feed every 4 to 6 weeks during spring and summer.
- If you grow Boston fern (Nephrolepis), it can benefit from slightly more frequent feeding.
- Do not fertilize in autumn and winter.
Erde & Umtopfen
Use a peat-free, well-draining mix rich in organic matter, and repot when needed.
- Use a peat-free “houseplant” or “fern” mix that drains well.
- Repot every 2 years, or when roots fill the pot.
- Choose a pot with drainage holes.
- For epiphytic ferns (for example, staghorn fern), mounting on wood is also possible.
- Do not use a pot without drainage holes.
Häufige Probleme
| Symptom | Mögliche Ursache | Lösung |
|---|---|---|
| Brown, crispy edges | Air is too dry, or the plant is too close to a heat source | Increase humidity with a humidifier or pebble tray, and move the plant away from radiators or vents |
| Yellowing fronds | Overwatering or poor drainage, sometimes low light | Make sure the pot has drainage holes, improve drainage, and let the topsoil dry slightly before watering again |
| Drooping or wilting | Underwatering, or occasionally root damage from compacted soil | Water thoroughly and let excess drain; if soil is compacted, repot into a fresh, airy mix |
| Fronds with spots, speckles, or webbing | Pests such as spider mites, scale insects, or mealybugs | Rinse the plant with lukewarm water, then treat with insecticidal soap or neem oil |
| Sudden leaf drop | Shock from drafts, sudden temperature swings, or transplant stress | Move to a stable spot away from doors and windows, and avoid handling after repotting |
