Why Ferns Indoors Low Light Is Easier Than You Think
Ferns indoors low light is one of the most searched topics among plant lovers — and for good reason. Many apartments and homes simply don’t get much direct sun. The good news? Ferns are one of the best plant families for exactly these conditions.
Here are the top low-light ferns you can grow indoors:
| Fern | Light Need | Difficulty |
|---|---|---|
| Bird’s Nest Fern | Low to medium indirect | Easy |
| Boston Fern | Medium indirect | Easy-Medium |
| Lemon Button Fern | Low to medium indirect | Very Easy |
| Button Fern | Low indirect | Easy |
| Blue Star Fern | Low to medium indirect | Easy |
| Rabbit’s Foot Fern | Low to medium indirect | Easy-Medium |
| Maidenhair Fern | Bright indirect | Moderate |
Most ferns evolved on forest floors, naturally shaded by a thick canopy above them. That means they’re built for low light. Many tropical fern varieties make excellent houseplants — undemanding, lush, and visually striking.
Beyond looking great, indoor ferns offer real benefits:
- Air purification — Boston fern is widely regarded as one of the best air-purifying houseplants, helping remove toxins like formaldehyde
- Natural humidity boost — ferns release moisture into the air, which is great for dry apartments
- Stress relief — their soft, feathery foliage creates a calming, green atmosphere
The only real challenge is matching the right fern to your specific light conditions and keeping humidity high enough. Get those two things right, and ferns are surprisingly forgiving.
Best Varieties for Ferns Indoors Low Light
When we talk about ferns indoors low light, we aren’t just talking about one single plant. There is a massive variety of textures, shapes, and growth habits to choose from. Whether you want a dramatic hanging basket or a tiny desk companion, there is a fern for that dark corner of yours.
Boston Fern (Nephrolepis exaltata)
The Boston Fern is the undisputed heavyweight champion of indoor ferns. Popularized during the Victorian era, it features lush, arching fronds that can grow 2 to 3 feet tall and wide. While it loves humidity (ideally above 80%), it is quite tolerant of lower light levels compared to many flowering plants. It’s a classic choice for hanging baskets where its fronds can spill over the sides.
Maidenhair Fern (Adiantum)
Known for its delicate, fan-shaped leaf segments and wiry black stems, the Maidenhair fern is the “diva” of the group. It is stunningly beautiful but requires high humidity and consistent moisture. It typically takes about three years to reach its mature size of 1–2 feet and can live for up to 15 years if you keep it happy.

Bird’s Nest Fern (Asplenium nidus)
If you want something that doesn’t look like a “typical” fern, this is it. The Bird’s Nest fern has thick, wavy, apple-green fronds that grow out of a central rosette (which looks a bit like a bird’s nest). It is much more slow-growing and can reach 3 to 5 feet tall, though it stays smaller in most homes. It is a great choice for large low light plants for lazy gardeners because it is tougher than its frilly cousins.
Button Fern (Pellaea rotundifolia)
The Button fern is a personal favorite for small spaces. It gets its name from its small, round, leathery leaflets that look like buttons on a string. It grows about 12 to 18 inches tall and wide. What makes it special for ferns indoors low light is that it actually prefers slightly drier air and soil than most other ferns, making it one of the easiest to keep alive in a standard home environment.
Rabbit’s Foot Fern (Davallia fejeensis)
This fern is a conversation starter. It features furry, light-brown rhizomes that creep over the edge of the pot, looking remarkably like a rabbit’s foot. These rhizomes actually absorb moisture from the air. It grows 1 to 2 feet tall and is excellent for hanging baskets or wall-mounted displays where those “feet” can be seen.
Blue Star Fern (Phlebodium aureum)
The Blue Star fern offers a unique color palette with its elongated, blue-green fronds. It’s an epiphyte, meaning in nature it grows on trees. Indoors, it reaches about 10 to 14 inches tall and is quite sturdy. It’s a fantastic choice for bathrooms where the steam provides the humidity it craves.
Beginner-Friendly Ferns Indoors Low Light
If you are new to indoor gardening, we recommend starting with these “forgiving” varieties:
- Lemon Button Fern (Nephrolepis cordifolia): This is a compact version of the Boston fern that only grows to about 12 inches. It’s incredibly resilient and even gives off a faint lemony scent when you crush the leaves.
- Kangaroo Fern (Phymatosorus diversifolius): With its leathery, oddly-shaped leaves, this fern is much tougher than it looks. It can trail up to 4 feet, making it perfect for a high shelf.
- Kimberly Queen Fern (Nephrolepis obliterata): Often considered the “neat” version of the Boston fern, it grows more upright and sheds less, making it a low-maintenance indoor plant that won’t leave a mess on your carpet.
Unique Epiphytes and Ferns Indoors Low Light
For the adventurous plant parent, some ferns don’t even need a traditional pot.
- Staghorn Fern (Platycerium): These are truly “living art.” They produce two types of fronds: flat “shield” fronds that cover the roots and “fertile” fronds that look like deer antlers. Staghorn Fern indoor care often involves mounting them on cedar boards with sphagnum moss. They can reach sizes of 60–90 cm indoors and prefer bright indirect light but can tolerate lower light if watering is managed carefully.
- Crocodile Fern (Microsorum musifolium): This fern gets its name from the texture of its leaves, which looks exactly like crocodile skin. It stays relatively small indoors (1-2 feet tall) and adds an incredible prehistoric texture to your collection.
Essential Care for Low-Light Indoor Ferns
Caring for ferns indoors low light is all about balance. You are trying to recreate the humid, dappled environment of a tropical forest floor within the four walls of your home.
Light Requirements
While we call them “low light” plants, no plant can grow in a windowless room with no light at all. The goal is “bright indirect light.”
- Best Placement: North-facing windows are the “gold standard” for ferns because they provide consistent, soft light without the heat of the sun. East-facing windows are also great for gentle morning sun.
- Avoid: South or west-facing windows can easily scald the delicate leaves. If you must use these, place the fern 1–2 meters away from the window or use a sheer curtain.
- Measurements: If you’re using grow lights, aim for 150–300 PPFD at the plant’s surface for 10–12 hours a day. Check out our guide on indoor plant sunlight requirements for more specifics.
Temperature and Humidity
Most ferns are tropical at heart.
- Temperature: They prefer a range of 60°F to 75°F. Boston ferns specifically love 65–75°F, while Maidenhair ferns should never dip below 60°F.
- Humidity: This is the secret sauce. Most homes have 30–50% humidity, but ferns prefer 50–70% (and Boston ferns want 80%+!).
- Pro-Tip: Grouping plants together raises local humidity by 5–10%. You can also use a pebble tray (a tray filled with pebbles and water that the pot sits on top of, not in) or a room humidifier.
Soil and Potting
Your potting mix should be rich but well-draining.
- The Mix: A high-quality potting soil amended with 20–50% organic matter (like peat moss or compost) is ideal.
- Pot Choice: Plastic or glazed ceramic pots are better than terra cotta because they hold moisture longer. Always ensure there are drainage holes!
Watering and Fertilizing Strategies
Watering is where most people go wrong with ferns indoors low light.
- The Top-Inch Rule: For most ferns, water when the top 1 inch of soil feels dry. The soil should be “consistently moist but not soggy.”
- Avoid Root Rot: Never let the bottom of the pot sit in a saucer of water.
- Watering Method: For epiphytes like the Staghorn, submerge the root ball in room-temperature water for 15–20 minutes, then let it drain thoroughly.
- Feeding: During the growing season (spring and summer), use a balanced 20-10-20 liquid houseplant fertilizer diluted to half-strength once a month. Cease fertilizing in winter when the plant goes semi-dormant. We have more tips for healthy houseplants to help you master the feeding schedule.
Troubleshooting Common Fern Problems
Even with the best intentions, things can go sideways. Learning to “read” your fern is key to keeping it alive.
- Brown Tips and Edges: This is almost always a sign of low humidity or underwatering. Increase misting or move the plant to a more humid room like the bathroom.
- Yellowing Leaves: This can indicate overwatering (leading to root rot) or a lack of nutrients. Check the soil—if it’s a swamp, stop watering immediately.
- Pale or “Bleached” Leaves: This is a sign of leaf scald from too much direct sun. Move it further away from the window.
- Leggy, Sparse Growth: Your fern is “reaching” for light. It needs a slightly brighter spot.
- Pests:
- Scale and Mealybugs: These look like small bumps or cottony spots. Treat them by dabbing with isopropyl alcohol or using insecticidal soap.
- Fungus Gnats: These tiny flies love moist soil. Let the top layer of soil dry out more between waterings to discourage them.

Propagation and Long-Term Maintenance
Once you’ve mastered ferns indoors low light, you might want to turn one plant into many!
Propagation by Division
This is the easiest method for most ferns like Boston, Maidenhair, and Bird’s Nest.
- Remove the plant from its pot.
- Use a clean, sharp knife to cut the root ball into sections, ensuring each section has a healthy clump of roots and several fronds (or “rhizomes”).
- Repot the new sections into fresh soil and keep them extra humid while they establish.
Propagation by Spores
Ferns don’t have seeds; they have spores. You can see these as little brown dots on the underside of the leaves. While it’s a slower process, growing from spores is a rewarding challenge for advanced hobbyists.
Maintenance and Overwintering
- Pruning: Regularly remove dead or browning fronds at the base (the crown) to encourage new growth.
- Repotting: Ferns like to be slightly root-bound, but if you see roots poking out of the drainage holes, it’s time for a pot one size larger.
- Overwintering: In winter, growth slows down. Reduce watering and stop fertilizing. For Boston ferns, you can even cut them back to 4 inches above the soil if they become too unruly indoors during the cold months. Check out our easy-care indoor plants for beginners for more maintenance-free ideas.

Frequently Asked Questions about Low Light Ferns
Can Maidenhair or Boston ferns survive in total darkness?
No. While they are marketed as “low light” plants, they still need light for photosynthesis. In a room with no windows, they will eventually die. If you have a very dark space, supplemental grow lights rated at 150–300 PPFD are necessary for survival and growth.
Are indoor ferns safe for cats and dogs?
Good news for pet parents! Most common indoor ferns, including the Boston fern and Bird’s Nest fern, are non-toxic to cats and dogs. However, cats often find the feathery fronds irresistible to play with. To protect your plant, we recommend using hanging baskets or elevating them on high plant stands.
How do I know if my fern needs more light?
The most common signs are “leggy” growth (long stems with few leaves), pale or yellowing fronds, and a complete lack of new growth during the spring and summer. If your fern looks like it’s “stretching,” move it a few feet closer to the nearest window.
