Indoor Fern is a beautiful addition to your home and can be placed in a bathroom or kitchen. If outdoors, it has the highest chances of survival in hardiness zones 10-12.

Origin And Family

Although initially discovered in 1753 by Carl Linnaeus, ferns have recently become popular among plant collectors, especially indoor plant collectors.

Indoor Fern Plant Size

Indoor Fern Care Needs

Your Indoor Fern will thrive beautifully even when given little care because ferns are usually low-maintenance plants. It likes to grow in evenly moist soil and low light that is indirect from sunlight. However, it is safe to expose it for a few hours to the morning sun, facing a window covered with a sheer curtain.

You’ll want to water your indoor ferns in most situations if the soil dries out. Heavily drench the ground until you see excess water from the pot’s bottom. As a humid environment-loving plant, it will be in its best health when provided abundantly with this requirement.

We’re making it easier for you to care for your Indoor Fern with the extensive list of tips below.

Care Difficulty

In terms of care difficulty, ferns are typically easy-to-care-for. The primary growing considerations are the soil and the amount of light this plant has.

Growth Rate

It grows to a mature height of 2-3 feet as a houseplant. Typically, you will notice faster and bushier growth during its growing season in the early spring and summer. Indoor ferns usually grow at a slow-to-moderate rate.


An essential requirement is that the pot contains at least one drainage hole. Leaving your fern plant in wet soil for extended periods could kill your plant.


Once your plant reaches a particular size, it is advisable to repot it into a larger container to maintain its health. When the roots begin to circle the container, it is time to repot the plant.

Indoor Fern grows slowly to moderately on average and must be repotted every two years. When repotting, adding nutrient-rich, loamy soil with excellent drainage is preferable, as the soil tends to lose its inherent nutrients over time.


Rich soil with good drainage is best for your fern plant. Compost, peat, and perlite are the ideal components for dirt, and aeration and drainage are also a must for this plant.

Here are some excellent growing medium options to choose from:

The ideal pH range for your plant is between 6.0 and 6.5, indicating that your fern prefers acidic soil. If you are regularly repotting this plant or adding new dirt, the pH level is less of a problem than if you were growing it outdoors.


Ferns are humidity-loving plants that require consistently moist soil year-round.

You should water your plant in the spring and summer if the soil becomes dry. Soak the ground until it drains through the hole in the bottom of the container. If you use a collecting or pebble tray, discard the water to prevent root rot and other infections.

During the winter months, less watering will be required. Continue to deeply water your plants, but less frequently.


Indoor Ferns do not enjoy direct sunlight much and prefer bright indirect light for 4 hours per day. Remember, you’re trying to recreate its growing conditions in the tropical regions of America, Africa, and Polynesia. Placing this plant in a bathroom or kitchen works well in most situations.

Avoid putting your Indoor Fern in direct sunlight, as this could severely damage or even kill it. You’ll know your Indoor Fern is getting too much light when its fronds burn. On the other hand, if it doesn’t get enough light, sparse fronds appear lackluster.


Water, sunlight, and soil are essential nutrients for indoor plants. Soil can lose its nutrient content with time, necessitating the addition of plant food.

Fertilize it once each month during the spring and summer if you want it to flourish. You may choose a liquid fertilizer or any regular liquid houseplant fertilizer but dilute it first if it is excessively concentrated. Regular winter fertilization frequency is every two months.

Propagating Indoor Fern

If the stem of your Indoor Fern has grown too tall, trim it back and store the cuttings away for propagation! Listed below are step-by-step instructions for various techniques of propagation.


Division is a propagation method typically used for plants that have pups shooting out from the roots.

You can divide the stem clusters of your by following these steps:

1. Dig up. Take the plant out of its container. You’ll be able to see where the plant’s natural divisions are.

2. Separate. With your fingers, gently separate the sections, and you may need to use shears to cut any entangled roots.

3. Repot. Plant each section in new pots filled with the same soil they’re used to.

Humidity And Aeration

Your indoor fern needs high humidity between 80% and above for rich-colored leaves and lush growth.

If you’re concerned about getting enough humidity for your fern or if you see brown leaves on your fern, you may purchase a humidifier and place it near your plants. This addition will make a big difference in your fern’s health.


Temperature ranges between 65-75 degrees Fahrenheit is best for your indoor fern. Sudden temperature swings can be fatal for your fern plant. Since ferns are not fond of cold temperatures, close windows and seal any openings where cold drafts may enter during the winter. Don’t place your plant near appliances that emit heat.


Most plants will typically bloom only when exposed to the natural elements.


Fern plants are not hazardous to children or pets. According to the ASPCA, it will not hurt dogs or cats if consumed, and there are no toxic elements in the plant.

Pests, Diseases, And Other Problems

Even with expert care, things can go wrong from time to time. Pests and diseases are unavoidable aspects of gardening, and as a whole, the Indoor Fern is not a disease and pest-resistant plant.

Read the following sections for ideas on diagnosing common issues and information on restoring your plant’s health.

Scale Insects

On the stems or leaves of your Indoor Fern, scale insects may manifest as bumps. Once attached to a plant, these little insects, which may be green, gray, brown, or black in appearance, are often sedentary.

If the infestation is not too bad, you can dissuade scale insects from attacking your plant with a teaspoon of neem oil diluted in four glasses of water. Spray the plant vigorously with a spray bottle.

Neem oil and horticultural oils might not kill the bugs, but they will definitely cause them harm. There are various pesticide sprays considered safe for indoor usage against scales.


There is a chance that mealybugs will infest your fern. If you observe these white-fuzzed parasites, take fast action. A cotton swab dipped in rubbing alcohol will kill mealies on contact and change their color to brown or orange. A spray of diluted Neem oil is also an effective preventative.

Brown Leaf Tips

A soil buildup of salts and minerals is a common reason for leaf edges turning brown on ferns. This often occurs when too much fertilizer is applied or chemically treated tap water.

Another cause of browning leaf tips is dehydration. Water your plant correctly and increase the relative humidity in your home.

Drooping Leaves

A wilting, droopy appearance on your Indoor Fern indicates distress. Possible causes of drooping leaves are overwatering, underwatering, excessive light exposure, lack of light, and low humidity.

Yellow Leaves

Sometimes, you may see yellow leaves on your fern, which can signify trouble. Factors that cause this problem include moisture stress, improper lighting, nutrient imbalance, inconsistent temperatures, insect infestations, bacterial or viral infections, and many others.

To narrow down the problem, you will need to consider any recent weather changes or how you care for your plant.

Root Rot

An overabundance of water due to frequent watering, which leads to root rot, is often fatal. Once decay starts to set in, it is difficult to control. Your best chance is to completely cut off the root system and restart your plant like you would when propagating a cutting.

Of course, you can always take certain precautions to prevent root rot in your potted fern. Start by giving your plant a fast-draining, well-aerated potting mix. You can do this by adding chunky materials to create air pockets and allow the roots to breathe.

Next, make sure you choose a pot for functionality, not just for aesthetics. The most essential requirement for houseplants is drainage. If there are no drainage holes on your chosen vessel, don’t be afraid to use your drill!

Finally, hold off on giving your plant a drink until you are entirely sure that the soil is no longer wet from your last watering. Stick your finger into the dirt, or use the classic wooden skewer trick to check for moisture.
