There is the ideal fern for every US climate zone thanks to the over 10,000 different types available. The USDA zones 2–10 are ideal for fern growth, depending on the kind. Some ferns can withstand freezing temperatures and flourish in zones 6-7.
The fern plants you have in the ground can stay there for the full winter. The middle crown of the plant, where new growth will appear in the spring, will be shielded by the fronds.
Ferns are resilient perennial plants that reappear every year. Many gardeners bring potted ferns indoors over the winter to continue growing. If a fern is planted in the ground, the great thing about it is that there is no need to winterize it.
The plant is shielded from the weather by the withered fronds. Any new growth that appears in the spring will be shielded by the drying and decomposition of the fronds. Simply remove the decayed foliage in the spring and let the fresh branches grow.
Winter death of house ferns?
We overwintered the ferns last year successfully, so we won’t need to buy any hanging baskets for the front porch this year.
When we put our Boston ferns outside last week, this is how they appeared. They seem nice, don’t they?
In the past, we’ve tried moving our ferns indoors and planting them near a window to overwinter them, but that always failed miserably. We simply spent the winter sweeping up little leaflets till the fronds were barren because no amount of watering or misting appeared to be able to make up for our hot, dry interior air.
Since the best plan was to move our ferns to the basement and give them monthly waterings until it was warm enough to move them back outside.
It is not necessary to provide your ferns with a light source (even a dark area is fine), nor do you need to take any special care of them. Because they will merely hibernate during the winter.
Finding a location in your garage or basement that doesn’t drop below 45 degrees can ensure that your ferns have a great winter.
Before bringing ferns indoors, some experts advise cutting the long-hanging fronds, but our approach eliminates the need for that.
But before you bring them inside, I do advise you to spray them down with an organic insecticide. By doing this, you can avoid bringing in any bugs.
You should create a reminder for yourself to water your ferns once a month since I can tell you from past experience that they won’t survive the winter if you don’t.
You can bring your ferns outside again whenever the outside temperature reaches the same level as your garage or basement (wherever you are keeping them). They will require some time to adjust to the sunshine again, so start by placing them in a partially bright area for a few hours, then gradually increase their sun exposure.
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.

Here’s to conserving your ferns for use the next year and cutting costs on your gardening expenses as well! Mary and Jim, happy gardening.
Will house ferns reappear?
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.

How should indoor ferns be cared for over the winter?
Tips for Winterizing Potted Ferns
- Trim the fern, leaving only the tallest shoots in the center and removing the sprouts on the outside of the pot.
- Bring the fern inside and put it in a space with lots of natural light and a constant temperature of 50 to 55 degrees Fahrenheit.
- Once every week, water the fern.
How are ferns maintained indoors?
There are numerous species of ferns that are endemic to more temperate climates in addition to the numerous tropical and subtropical fern species. These ferns would thrive in cooler portions of the house but won’t endure in overly warm spaces. The best climate for tropical ferns is a house with central heating. The recommended indoor fern-growing conditions are listed below:
Humidity
All ferns enjoy wetness, hence they should all be kept in humid environments. Stand the pots in the living and family rooms on trays of wet pebbles or clay granules. Except in situations where a humidifier is used to maintain a high level of humidity across the entire space, ferns also enjoy being misted often with tepid, soft water.
Compost/Soil
Additionally, you must offer the proper compost. The majority of ferns are woodland or forest plants with fragile, soft roots adapted to the light forest soil that is rich in leaf mold and decomposing plant waste. To prevent the roots from ever becoming soggy, the ideal compost must be freely draining. The finest compost is one that has peat or a fibrous peat substitute together with lots of sand. The plant may need to be watered a little bit each day in a warm, dry environment in order to prevent the compost from drying out.
Light
Though the majority of ferns prefer wet, shaded environments like forest floors, this does not imply that they are light-independent. If the lighting in your home is excessively dim compared to their natural environment, you will notice poor growth and fading fronds. Keep your ferns away from direct sunlight, especially in the summer, and place them close to a window that receives morning or late-afternoon sun. They will either lose their leaves or have yellowed fronds if exposed to direct sunshine.
As long as you give your ferns periodic pauses in strong light, you can keep them in low light. They can receive artificial light, but it should come from a fluorescent strip or a specific gardening bulb. The heat produced by standard light bulbs is too much.
Temperature
How high or low of a temperature a given fern requires will depend on its origin and adaptability. Most ferns dislike chilly weather. Tropical ferns really enjoy temperatures between 60 and 70 F. (15-21 C.). People from drier climates prefer temperatures of 50 to 60 F. (10-16 C).
Fertilizer
Every two to four weeks during the summer, give your ferns a liquid fertilizer feeding, but don’t mix it at full strength as this could harm the roots. For misting, a few drops of fertilizer can be sporadically added to the water. Because they relax during the winter, don’t feed your ferns. Mist your ferns frequently to keep the air around them moist.
Repotting
Spring is the best season to repot ferns, but only if the pot is completely filled with roots. If not, simply remove the compost’s top layer and add more compost in its place. To promote fresh growth, remove any broken fronds.
Make two ferns out of one when you repot them by cutting them in half. The powdery spores that are produced in tiny capsules can also be used to create new ferns. On the underside of the fronds, rows of rusty, brown blotches represent these capsules. These will develop into a green coating, which will then support the fern.
Why is the fern in my house dying?
It usually happens when a fern drowns or the humidity is too low, which dehydrates the leaves and causes them to become brown and crispy. To prevent the leaves from turning brown and dying, indoor ferns need soil that is continually moist, and they like a humidity level of 50%.
The majority of indoor ferns, including Boston, Maidenhair, Birds Nest, Rabbit Foot, and Asparagus Ferns, are indigenous to tropical climates where they flourish in high humidity, continuously moist soil, cool, constant temperatures, and shaded areas under tree canopies.
It’s crucial to recreate the fern’s natural environment in order to bring it back to life. To do this, you should raise the humidity, put the fern in moist organic soil, and place it in a shaded spot with a consistent, moderately cool temperature.
