Underwatering, low humidity, and extreme heat or cold are the three most frequent reasons why fern plants lose their leaves.
A fern that is losing its leaves can be revived by increasing the humidity, watering more frequently to keep the soil continuously moist, and maintaining a temperature between 65 and 75 degrees Fahrenheit. Once these conditions are met, new leaves should begin to sprout.
- Use a humidifier to raise the humidity to 50%. A humidifier is the most efficient approach to raise the humidity surrounding your fern because you can adjust the humidity level with some humidifiers, accurately simulating the greater humidity levels seen in the fern’s native tropical environment. This lessens water loss from the leaves and fosters the ideal atmosphere for your fern to begin recuperating by generating new leaves.
- Mist your fern daily and place it near other potted plants. Your withering fern will thrive better if you cluster multiple plants close together to create a humid microclimate. The leaves lose less water when misted, and your fern shoulder begins to recover.
- So that the soil is regularly and equally moist, water the fern as often as necessary. There is no set schedule for watering ferns because it depends on the size of the plant and the relative humidity of the space. However, to make sure that the soil is moist but not saturated, I advise constantly probing the ground with your finger. Always water deeply, allowing excess water to flow out of the drainage holes in the pot’s base to confirm that the moisture has gotten to the roots where it is needed.
- To rejuvenate your fern, maintain a temperature range of 65 to 75 degrees Fahrenheit, with a slight drop at night. Low temperatures stress tropical ferns, and higher temperatures enhance evaporation, which increases the chance of leaves falling. In order for the fern’s leaves to regenerate, maintain the temperature within the ideal range to mimic the fern’s native environment.
- Away from heat sources, air currents, and drafts, keep your fern. Maintaining the proper humidity levels is crucial for your fern to recover, so keep it clear of drafts and away from artificial heat sources that might dry up the leaves.
The fern should recover under ideal environmental circumstances, and during the growing season, new leaves should appear.
Why is the fern in my house dying?
Ferns prefer moist, but not wet or muddy, soil. Wet soil can lead to root rot while dry soil can cause wilting and eventually drying out. You might need to water often when the temperature is above 75 degrees Fahrenheit to keep the soil moist to the touch. Wait until the soil’s top is dry if the temperature is below 60 degrees. Exceptions that want the soil to slightly dry before watering include Japanese holly fern (Cyrtomium falcatum, zones 6 through 10) and rabbit’s foot fern (Davallia fejeensis, zones 10 through 12). Dry peat moss, which most ferns want a lot of, resists water, and the dense mass of roots makes it difficult for moisture to penetrate, so once a pot dries out, it could be challenging to water the fern. To replenish the soil moisture, soak dried-out pots for about 15 minutes in a pail of water that sits just above the lip of the pot. After soaking, put the pot in a sink to properly drain.
Can you bring back a dead fern?
If you set the right conditions for growth, you can revive a dried-out fern. Since most ferns are hardy plants, once the problematic conditions are fixed, they usually recover within a few weeks.
The good news is that the fern will grow again in spring once the temperatures rise, even if it is dead now, which is typical in frigid temperatures during winter.
Steps to Revive A Dried Out Fern:
First, water the plant and give it an hour to soak. Run a knife around the rootball and tap the pot against the edge of a table. Take the plant out of its container.
Step 3: Remove fading or dead roots and tease out tangled roots. Keep the healthy ones alone.
Step 4: Insert a piece of wire mesh into the bottom of a fresh pot. Organic soil that has been well-drained should fill the pot’s lower half.
Step 5Set the plant in the center and gradually enlarge the area around it with potting soil. With your thumbs, compress the compost.
Step 6: Water the compost to keep it damp but not drenched. Between waterings, the compost should be dry.
Step 7Sit the pot in full sunshine on a windowsill that faces north.
How to save a fern from dying?
A fern that is being grown indoors or outdoors is almost certainly dying from inadequate drainage. The soil or potting mix used outdoors must have good drainage. The clogging of drainage holes does occur frequently. Take a pencil and insert it into the drainage hole to see if that is what happened to you.
Because the fern has outgrown the pot, it may occasionally be drying out or dying. In this situation, repotting the plant right away can be too much of a shock for it. Keep it in the same pot until it has recovered, and then you can repot the fern in a larger container if you notice fresh growth.
How to revive a dried out fern in a pot?
Keep the fern in its container and trim any dried-out fronds to a length of 2 inches, leaving the healthy, green leaves alone. The center should have robust upright fronds. Delete the top 2 inches of the compost, then add new potting soil.
Soak a plant in a big bucket until it totally drains. Place it in bright light, away from the sun, on a windowsill or in the open air. Repotting ferns should generally be done in the spring when the roots have filled the pot. Repotting young specimens should be done once a year.

What can I do to revive my fern?
Repotting is a huge shock, making it the worst procedure to apply on a frightened plant. Wait until midspring, when it has recovered and is actively growing, if your Boston fern needs a bigger pot. Leave any healthy erect fronds in the plant’s center unharmed and shorten any drooping fronds to around 2 inches in length. Trim all fronds to 2 inches if they are all drying and withering. Remove any dead foliage and look for offsets (baby ferns) in the soil that may be separated and put in separate pots. Boston ferns typically reproduce through stolons rather than spores and are sterile in nature. In case the nighttime temperature drops below 50 degrees Fahrenheit, soak your fern thoroughly and let all the water drain out of the drainage hole before laying the pot on a tray in bright light.
What appearance does an overwatered fern have?
Although Boston fern needs slightly moist soil, soggy, waterlogged soil is more prone to cause rot and other fungal diseases. Yellowing or wilted leaves are frequently the first indication when a fern is overwatered.
Touching the dirt with the tip of your finger is a guaranteed technique to tell when to water a Boston fern. It’s time to water the plant if the soil’s surface feels a little bit dry. Another sign that a fern needs water is the weight of the pot. The pot will feel quite light if the soil is dry. Wait a few days before watering, then retest the soil.
Use water that is room temperature to thoroughly water the plant until the water flows through the bottom of the pot. Never let the pot stand in water and always allow the plant drain completely.
If you create a humid environment, Boston fern watering will be improved. A tray of wet stones is a more efficient approach to raise the humidity surrounding the plant than occasionally misting the fronds.
Set the pot on a layer of damp pebbles or gravel that has been spread out on a plate or tray. To keep the pebbles continually moist, add water as needed. Make sure the pot’s bottom doesn’t come in contact with water, as root rot can result from water leaking up through the drainage hole.
Do you need to prune back dead ferns?
You should remove any brown or yellow fronds from indoor ferns to improve their appearance. The ventilation surrounding the plant is improved by removing these dead fronds, which aids in preventing fungal or mold issues. Check the soil if you notice that the fronds of your indoor fern frequently wither away. When kept in wet soil, ferns will become yellow, whereas those that receive little moisture will turn brown. Feed your fern with a modest amount of low-nitrogen fertilizer if the soil is wet.
How may Epsom salt benefit ferns?
Epsom salt has a magnesium content of 10% and a sulfur content of 13%; applying it can raise both. Additionally, we are aware that they rank behind only nitrogen, phosphorus, and potassium as essential nutrients. They support the growth of healthy plants, the generation of chlorophyll, and pest and disease resistance. If you want to cultivate lush and green ferns, you need both of them.
Why is my fern becoming crispy and brown?
At the end of the Fall season, trim the leaves back when they begin to brown since they are unable to photosynthesize anymore. This neatens up the fern’s appearance and enables you to mulch the fern’s underground rhizomes with compost to help keep them warm over the winter. The fern should recover healthily the following spring.
When growing ferns in sandy soil that dries out too fast after rain or irrigation, add heaps of compost, leaf mold, or well-rotted manure to the planting area.
These three materials all have a porous structure that allows extra water to flow away from the roots, preventing root rot even though they retain a lot of moisture.
As ferns cannot withstand excessive amounts of direct sunshine, always plant them in locations with shade or some filtered light. Either move the fern to a more shaded area or grow additional trees or bushes to provide shade.
Key Takeaways:
- Low humidity and drowning lead fern leaves to become brown. Ferns are tropical plants that require high levels of humidity. Indoor humidity is frequently too low, which causes the leaves to lose moisture and turn brown, crispy, dried out, and look to be dying.
- Due to submersion, fern tips become brown. The soil must be continually damp, but not saturated, for ferns to grow. The fern’s leaves get brown and crispy at the tips if the soil dries up in between waterings because there isn’t enough moisture surrounding the roots.
- Smaller pots dry up faster. Because ferns require continually moist soil, their leaves will turn brown and brittle and will appear to be dying if the potting soil dries out. Because ferns often have large, shallow root systems, they can easily become pot-bound in small pots, which can turn their leaves brown.
- In much sunshine, fern leaves oxidize and turn brown. Ferns may survive in either complete shade or partial light beneath a woodland canopy. The delicate leaves become crispy and brown in full sun, appearing to be dying.
- If the temperature is above 80F for a prolonged period of time, indoor ferns may turn brown. Ferns prefer temperatures between 65 and 75 degrees Fahrenheit. The ferns’ leaves become brown and crispy and appear to be dying in high temperatures because the leaves lose too much moisture and the soil dries out too quickly for the roots to pull in moisture.
- In the Fall, just before Winter, outdoor ferns naturally turn brown and appear to be dying. The following Spring, the fern sprouts fresh, green leaves. If the ground is too dry or there is too much sun, outdoor ferns may also turn brown. To keep its leaves from turning brown, outdoor ferns need moist soil and shade.
- Use a humidifier to raise the humidity, water as often as necessary to keep the coil consistently moist, stay away from drafts and indoor heating, place the fern in an area with indirect light, make sure the temperature is between 65°F and 75°F, and cut back brown leaves to encourage the growth of new green leaves in order to save ferns with brown leaves.
Avoiding A Hard Frost or Freeze
Getting ferns out of harm’s way before the brutal cold sets in is the first step in rescuing them. Ferns can withstand a little bit of chill and even a light frost, but not a harsh freeze or frost.
Plants need to be covered or moved indoors on nights when a strong frost or freeze is anticipated as the temperatures start to decrease in mid- to late fall.
Unfortunately, it’s too late to salvage a fern after it has been exposed to a heavy frost or freeze. In light of this, it is a good idea to get your fern ready for overwintering before a lot of cold nights arrive.
Cutting Back / Pruning
Pruning is the first step in preparing for indoor overwintering. Anyone who has ever raised a fern is aware of how big they can get during the hot summer months.
To start, trim down any long foliage strands to make a more manageable indoor plant. If necessary, don’t be afraid to shave off a few inches or even more of growth. It will, in fact, eventually regrowth.
The next step is to thoroughly rinse your plant with a spray from your garden hose. This will not only get rid of any cuttings but also hose off any bugs that might be hiding inside the plant.
Spray the entire plant down after lifting the leaf. After all, nobody wants to provide any outdoor insects with a new home!
You are now prepared to bring your plant inside, unless it has gotten too huge and needs to be divided. Near the article’s conclusion, we have how-to information for that problem.
Bringing IndoorsSaving Ferns
Allow your fern to completely dry out before bringing it indoors if it hasn’t split. Ours are actually dried out entirely by hanging them in the sun for an afternoon on our clothesline.
Finding the ideal indoor overwintering spot is the next step. The area must be kept cool while being shielded from cold temperatures. Many people find a basement to be ideal, but a garage or even a cool area of the house also works well.
Ferns can survive the winter months without full sun or intense light. In fact, too much window light might cause the plant’s leaves to burn.
Keep children away from windows with southern exposure in light of this. With just sporadic ambient light from a garage window or even a basement well window, they can easily thrive.
Other than the occasional watering, there is no need for fertilization or much care at all. Every five to seven days, check the soil, and only water when the soil is absolutely dry.
Keep in mind that your goal at this point is not to grow a beautiful plant inside. Instead, you are merely overwintering the fern to keep it alive until the warm summer months, when it will once more flourish.
Realize the plant won’t look its best knowing this. The leaves will undoubtedly become paler before spring returns. Some will drop to the ground as well. All is well!
Allowing your plant to return to the outside can help it restore its vitality, energy, and color as soon as the weather warms up. Again, make careful to guard it against spring frosts and freezes as well. Now let’s talk about those enormous ferns.
Saving FernsRepotting & Dividing
Fall is the ideal season for dividing and replanting ferns that are very huge or have outgrown their containers. A decent general rule of thumb is to split the fern to a third of its size for its present container if you want to preserve the same size fern for the following year.
It is advisable to remove all of the foliage from split and divided plants up to a few inches from the base. After that, you can repot the fern by filling the area around the container with high-quality potting soil. (See: Making Excellent Homemade Potting Soil.)
At this point, you can also repot the other divisions to accommodate extra plants. The ferns will partially regenerate from the cuttings over the winter, but once outside, they will fully recover.
