Are ferns toxic to cats?

No, ferns are not toxic to cats. All indoor ferns like Asplenium (bird's nest), Nephrolepis (Boston fern), Phlebodium, and Microsorum are completely safe if ingested. They are perfect for homes with pets because they combine safety, beauty, and the ability to naturally purify the air.

What is the easiest fern to care for?

Nephrolepis (Boston fern) is the easiest fern to care for. It tolerates humidity changes better than other species, adapts to medium light, and forgives occasional missed waterings. Asplenium (bird's nest) and Phlebodium aureum are also tolerant and perfect for beginners who want a lush green plant.

Do ferns need a lot of light?

No, ferns prefer shade or indirect light. They thrive in low-light rooms, away from windows or in bathrooms without direct light. Direct sunlight burns their delicate fronds and causes rapid drying. This makes ferns ideal plants for dark spaces where few other plants survive.

How often should you water an indoor fern?

An indoor fern needs watering every 3 to 5 days to keep the soil slightly moist at all times. Never let the soil dry out completely but avoid standing water, which causes root rot. In winter, reduce watering slightly to every 5-7 days as growth slows and evaporation decreases.

Why is my fern drying out?

A fern dries out due to a lack of humidity or insufficient watering. The fronds turn brown and become crispy when the air is too dry (heating, air conditioning) or when the soil dries out too much between waterings. Increase ambient humidity with a humidifier, mist the fronds regularly, and keep the soil consistently slightly moist to fix the problem.

How large can an indoor fern grow?

An indoor fern reaches 40 to 80 cm in height and width depending on the species. Nephrolepis can exceed 1 meter when hanging, Asplenium forms a rosette of 50-60 cm, and Phlebodium reaches 60-80 cm. Their growth is moderate (10-20 cm per year) and they maintain a compact, dense shape, ideal for creating a lush tropical atmosphere.

Do ferns purify the air?

Yes, ferns purify the air by filtering formaldehyde, xylene, and toluene. Nephrolepis (Boston fern) is especially effective at improving indoor air quality according to NASA studies. They also increase ambient humidity through transpiration, creating a healthier and more comfortable environment, especially in winter with heating.

How can I increase humidity for a fern?

Increase humidity for a fern by using a humidifier, misting the fronds 2-3 times a week, or placing the pot on a tray of wet clay pebbles. Grouping several plants together also creates a more humid microclimate. The bathroom is the ideal location for ferns because natural humidity is high there.

Why are the leaves of my fern turning yellow?

A fern’s leaves turn yellow due to overwatering, lack of nutrients, or exposure to direct sunlight. Waterlogged soil causes root rot and yellowing fronds. Reduce watering, check the pot’s drainage, apply diluted liquid fertilizer once a month in spring and summer, and place the plant in indirect light.

Indoor ferns — airy fronds, shade, and freshness

Ferns have existed for over 360 million years and have lost none of their charm. Wavy, cut, bluish fronds or shaped like deer antlers: they bring an unmatched lightness to the least bright rooms. Shade-tolerant, fond of humidity, and non-toxic for the whole family — including children and pets.

Ferns have existed for over 360 million years — long before flowering plants, dinosaurs, and even the first trees. Indoors, they bring a unique touch of freshness and lightness with their airy, divided fronds. Shade-tolerant, moisture-loving, and non-toxic: they are perfectly suited to urban interiors and the least bright rooms.

The timeless classics: Asplenium and Nephrolepis

Asplenium (bird's nest fern) is the easiest fern to care for. Its large, wavy, bright apple-green fronds grow in a regular rosette and add generous volume. The Nidus, Parvati, Osaka, Campio, Crispy Wave, and Crissie varieties each offer a different frond texture — from smooth waves to curly crepe. The Nephrolepis (Boston fern) is the archetype of the trailing fern: its long, arching fronds cascade luxuriously over the pot. The 'Macho' variety reaches impressive sizes up to 100 cm. Discover our Asplenium collection.

Graphic and original ferns

The Phlebodium (blue fern) stands out with its blue-gray foliage cut into rounded lobes — a unique color in the fern world. The Platycerium (staghorn fern) is the most spectacular: its forked fronds resemble deer antlers, making it a living wall piece. The Microsorum Crocodyllus (crocodile fern) intrigues with its textured fronds reminiscent of reptile skin. The Microsorum diversifolium (kangaroo fern) offers more divided, trailing foliage. Explore our Phlebodium and decorative foliage plants collections.

Rare and collector ferns

The Aglaomorpha coronans is a spectacular epiphytic fern with divided fronds that can exceed 60 cm in length. The Davallia bullata (hare’s foot fern) develops hairy rhizomes that spill over the pot — a fascinating sight. The Humata tyermannii (bear’s foot fern) has similar silver, fuzzy rhizomes. The Blechnum Silver Lady with its silver fronds and the Polystichum tsussimense (Korean fern) with finely cut fronds complete the collection for rarity enthusiasts. Discover our collector plants collection.

Where to place your ferns?

Ferns are understory plants: they prefer partial shade or bright shade and dislike direct sunlight, which burns their delicate fronds. The bathroom is their favorite room — warmth, humidity, and filtered light recreate their natural conditions. They also do very well in a bedroom, hallway, entrance, or office away from the window. The Platycerium can be hung on the wall, the Nephrolepis suspended, and the Asplenium placed on furniture. Check out our article light and humidity: finding the right balance and our guide indoor plants for every room.

Indoor fern care

Humidity is key. Ferns love humid air (50-70%) and a substrate that never dries out completely. Water regularly — as soon as the surface of the substrate starts to dry — and mist the foliage several times a week, especially in winter when heating dries the air. Use non-calcareous water to avoid white spots on the fronds. Avoid hot drafts and placing them near radiators. Our complete watering guide and our month-by-month care calendar help you find the right rhythm.

Hanging ferns: airy decor

With their naturally trailing or spreading habit, many ferns are ideal for hanging. The Nephrolepis Green Lady is the classic choice for macramé. The Davallia and Humata, with their overflowing rhizomes, create a striking "living suspension" effect. The Phlebodium and Aglaomorpha in Kokodama (suspended moss ball) are ready-to-hang arrangements. Discover our hanging and trailing plants and decorative hanging plants collections, and read our guide hanging plants: the best species.
