Why is my Fern Drying Out?

The ferns (Nephrolepis) can be described as an old superior class of plants. They thrive in humid forests, ponds and wetlands.

The spores and bush division are the principal methods for propagation. This plant can enhance any indoor.

Pests such as scale insects as well as spider mites, aphids and mealybugs may dry out a fern’s indoor leaves. The wrong temperature, light, and humidity may cause ferns to dry up. Keep dry out by keeping the plant at 65 to 75 degree F and with a humidity of 60. Apply a mixture consisting of soap, oil from neem, and alcohol to rid the plant of insects.

Indoor ferns are typically low-maintenance plants. However, occasionally, you might notice dry and yellowing leaves. To fix this problem it is first necessary to determine the cause.

Causes of Fern Drying Out and What to Do

Mistakes With Watering

If you can determine why the indoor fern began to dry up in the beginning, you can quickly restore it to its former glory.

However, the reality is that most times the fern dies due to it isn’t getting enough water.

The health of ferns can be damaged by insufficient or excessive hydration of the soil used for potting.

In general, when you overwater the plant, the lower leaves change color and the tips begin to dry out.

The roots of your ferns are especially susceptible to fungal growth and rot since they are always submerged in water.

The lack of water causes the plant to appear slow and sluggish. the growth rate slows dramatically. The leaves of the plant change to yellow and then dry out.

It is easy to tell when it’s time to water your plant by taking a look at the soil If it’s dry on top, then you should sprinkle water.

It is essential to keep your fern hydrated every two to three days during the summer months when the temperature is hot enough.

I suggest watering with chilled or filtered water. If you use water that is too hard, cold or chlorinated water could result in the leaves to yellow as well as curling.

In the summer you can water your ferns at night; in the winter months, water it early in the morning.

After watering, the soil must be looser if there’s an obvious crust.

In general you should sprinkle your fern at minimum once per week with just lukewarm, settled or filtered water.

Fluctuation In Temperature And Humidity Levels

Examine the area where your fern grows to determine if it has been able to stop growing or if its leaves have dried out. The fern thrives under these conditions

  • A temperature of 60 degrees Fahrenheit is common in the winter months.
  • In the summer, temperatures should be around 72 degrees Fahrenheit.
  • A humidity level at or above 60 percent is suggested.

The fern should be sprayed more often whenever temperatures rise above the 77 degree mark (25degC) because this helps to moisten the air further.

Reduce the amount of water you drink if temperatures drop below 54 degrees Fahrenheit (12 degrees Celsius).

The leaves’ color changing as they age is normal in the process of aging. Get rid of the dried leaves by cutting them.

If the fern’s leaves start to fade and cease to grow The air inside the room is dry and the fern is just overheating.

The dark brown marks on the leaves could also be because of these conditions.

A systematic spraying schedule twice per day both in the morning and the evening is all you need to establish a comfortable indicator.

Ferns should get an easy shower when it’s hot outside. Make use of polyethylene or another waterproof materials to prevent the soil from getting too wet.

In addition, expanding clay, peat, or sand can help improve drainage.

Keep ferns away from heating systems and heaters as much as you can in the winter months when temperatures are cold.

Adding Too Much Or Too Little Fertilizer

If you fertilize in the incorrect way, it could cause a lot of problems for ferns.

Feed the flower only when it is growing actively between March and September.

You should feed your indoor fern one or twice per month I would suggest cutting down the amount to half the amount recommended on the label.

It is possible to use any fertilizer that is suitable for ornamental or deciduous plants.

Stop fertilizing between October and March, when the plants are dormant.

Another reason that could be causing dry out of the fern leaf or a slowing of growth, is the lack of nutrients or space for the root system within the pot.

If the fern is living in the container of a smaller size it is recommended to transfer it to an even bigger one and feed it.

Incorrect Lighting

When leaves get exposed excessive direct sunlight over a long time, they’ll be less attractive and lose their aesthetic appeal.

If you don’t give an environment that is well-lit, your fern’s growth will be slowed.

If leaves are exposed to too much sunshine will lose color, turn dull, and then dry out.

It’s allowed to be outdoors in the sunshine for two hours per day, but not longer.

Transfer your ferns that have fallen and dried foliage to the east or north of the room, so that they’ll feel more at home.

Is It A Pest Or A Disease That Causes Leaf Spots?

The signs of yellowing and discoloration of the fronds of your fern suggest that you should inspect the fern for insects or disease.

It is imperative to take immediate action and take the appropriate steps to eliminate these symptoms as quickly as you can.

Take into consideration that If you take care of your ferns properly and pay them the proper care, the chance of developing disease is very low.

Common Pests of Ornamental Fern


Scales are the largest and most frequent insect that is found in Nephrolepis however unfortunately, it’s difficult to detect that the scale is present at any the same way as the fern.

At the height of infestation and then begins to dry out and drop off the leaves.

The issue lies in the fact that this scale is located on the bottom of the leaves and is difficult to differentiate this from flower spores.

Then, trim the infested leaves beneath the petiole. Then, remove the scales using a brush.

The fern will then be susceptible to being sprayed using Horticultural oil. Make the solution at the amount of 20 drops for 1 Liter of water.

Spider Mites

The ferns you have may be killed due to the presence of this insect. Additionally the spider mites that sucking sap from the fronds can cause serious harm: the fronds dry out, become pale and then fall off.


They enter the root system due to inadequate irrigation. So, nematodes are able to be eliminated by planting new soil that is enriched by organic compost.


If the air inside the home is dry, the insect could attack the plant.

Treatment of leaves using insecticide soap solutions such as neem oil or ruby alcohol can help when the infestation is extensive.

In the event that infestations are serious If the infestation is severe, take out the affected parts from the plants.


The mealybug also suckers up the juices of your ferns. In the end, the growth and development of your fern is slowed.

In addition, the insect is able to be found in a variety of plants, ranging from cacti to orchids and azaleas.

In appearance, it’s tiny, agile bug that has a white-colored cover.

Usually, you will see them in groups on buds, young shoots or on the rear of the fronds.

There are a number of infusions that contain alcohol, laundry soap, and oils to rid yourself of the insect.

The most important step is to mix all ingredients and let them be thoroughly infused.

Then, use detergent and alcohol wash leaves from fronds.

Then, just wipe off the cocoons off of the areas.

In lieu of olive oil as a substitute, you could make a tincture from garlic. Many gardeners suggest that calendula tincture can be ideal to wipe.

Newly Replanted Ferns Turn Yellow and Dry Out

If the fern is properly taken care of, it won’t require repotting.

As long as the plant is not at 3 years old, I suggest you follow these steps every year between April and May.

Then, it’s just every couple of years. This requires pots that are not too deep, but large enough to hold the root system of the plant without being too large.

Take away any dry leaves, twigs and branches using attention before proceeding. Whatever your efforts, the plant might not always be willing to endure such a harsh treatment.

It may take a while for the fronds’ young ones to develop. The fern was just repotted and it started to dry up So what do you do?

First, establish all the conditions that will allow the growth of the fern and then allow a couple of weeks for the fern to adapt to its new surroundings.

When transferring ferns, be extra cautious with tips as they are the primary growth points. Ferns will eventually die and become dry if these growing points have been damaged.

Find out the cause or missing and the reason why a fern that is ornamental becomes yellow and then begins to dry out isn’t easy at times However, it’s not impossible.

Ferns Drying out Due to Diseases

Insufficient watering and low temperatures can lead to gray rot, sooty mold, as well as other fungal infections.

It is not a good idea to seek assistance from experts regarding how to manage them since there is no cure when you are diagnosed with the disease.

It’s therefore crucial to swiftly remove the fungus-infected ferns from healthy ones in order to prevent them from becoming sick.

Fungicides will not save the fern and the fern is likely to die and dry up. Prevention is the best treatment for these kinds of situations.

Make sure that your soil and the air remain at the right humidity and temperature, and then ensure that your plants are properly watered to fight off the disease before it begins.

Pests and overwatering are other elements that can affect the overall health of a plant.

In order to keep your ferns healthy, you’ll have to determine the cause of the problem and then gradually establish the conditions for comfort.
