Benefits of Bird’s Nest Ferns

They’re Perfect As a Hanging Plant

Because of their wide, ribbon-like foliage, bird’s nest ferns make lovely hanging plants. Since this type of fern does best in the shade and indirect sunlight, keeping them in hanging pots indoors is the best way to go. Plus, bird’s nest ferns can grow quite wide and reach a diameter of four feet. Imagine how incredible a bird’s nest fern would look hanging in your home!

This type of fern does best in low to medium indirect, though it can thrive in bright indirect light. It’s vital to give this fern some shade and to keep it away from too much direct sunlight. If your fern is kept on a windowsill, the fronds will eventually turn yellow and die.

If you don’t have a ton of natural sunlight in your home or you’re stuck in an office or dorm, you’re in luck! Bird’s nest ferns do wonderfully in shady spots with indirect sunlight.

Bird’s Nest Ferns Filter Formaldehyde, Xylene, and Toluene

These chemicals hang in the air and can be caused by cigarette smoke, cleaning supply vapors, and polluted air. Formaldehyde in particular can cause coughing, wheezing, and burning sensations. Bird’s nest ferns (and most ferns in general) are one of the few plants out there that can effectively filter out these chemicals!

Care for Bird’s Nest Fern

Light

This fern is very easy to care for and is an excellent choice for beginners. Keep your plant away from direct sunlight, but keep it in a room with windows so it can get indirect sunlight. This fern does well when it’s slightly rootbound, meaning that it prefers a smaller pot to a large one.

Water

You should only water your bird’s nest fern weekly and test your soil moisture level regularly, as this plant cannot handle excessive amounts of water. A great way to give your ferns root rot is by overwatering! Check your soil moisture regularly by sticking a finger into the soil. It should be slightly damp, not soggy or bone dry. If the soil is dry, add about an inch of water.

Humidity & Temperature

A misting bottle is a must-have for bird’s nest ferns. This jungle plant loves humidity and will thrive in a warm household where it is occasionally misted with clean water. Aim for the fronds when misting. It may even be beneficial to top your soil with a layer of mulch to help it stay damp. If your bathroom has a skylight or window, an Asplenium nidus would do quite well in that environment.

Bird’s nest ferns love warm temperatures. They’re native to tropical places like Hawaii and Polynesia after all! Keep your fern in a room that is between 70 and 90 degrees F (21 and 32 C) to keep it as healthy as possible. Temperatures that are slightly outside these ranges won’t hurt your plant, but its growth may slow significantly.

Fertilizer

Because they are such a slow-growing species, Asplenium plants do not need very much fertilizer. However, they can benefit quite a bit from monthly treatments. The best fertilizer for a bird’s nest fern is a balanced 20-20-20, water-soluble liquid fertilizer. Mix 1 tablespoon of fertilizer into 1 gallon of warm water. Apply the treatment to the soil surrounding the plant no more than once per month.

Pruning a Bird’s Nest Fern

Bird’s nest ferns do not need to be regularly pruned. When fronds on the underside of the plant grow old and “crispy,” remove them with sharp pruning shears.
Common Care Mistakes to Avoid

Even though the bird’s nest is an easy beginner plant, there are some common mistakes that plant parents should avoid:

  • Never water the center of your plant (a little reservoir known as the “rosette”) because it will trap water and cause your fern to rot.
  • Don’t keep your bird’s nest fern in a plastic or lightweight pot. They enjoy being rootbound but will become top-heavy as they grow, and will tip over. Opt for a ceramic or other heavy material for your pot.

Avoid placing your fern in a high-traffic area, such as right beside a door or in narrow walkways. The fern’s fronds are very fragile, and constant bumping will cause them to die.

Propagation of Bird’s Nest Fern

The best way to propagate your bird’s nest fern is through spores.

To do this, simply remove a large, mature leaf from your plant using clean and sharp shears. Place the leaf inside of a paper bag. Around two days later, check the bag. The spores will have fallen from the frond and will appear as brown, fuzzy spots. Place these spores on top of a pot with a mix of sphagnum moss, peat moss, and dolomite. The pot should have a drainage hole in the bottom. To water these spores, place your pot in a shallow dish with water and let it soak upward through the soil.

Moisture is key to propagating a bird’s nest fern. Cover the pot with plastic wrap or mist daily to help the spores propagate. After around two weeks, you should have the beginning of a new bird’s nest fern!
