Ferns naturally grow in moist, shaded places like swamps and riverbanks, but they can also flourish in indoor container gardens and outdoor garden beds. Ferns are low-maintenance perennial plants that are simple to grow and give lush greens to any home garden setting. They are also resistant to most illnesses and pests.
Are indoor ferns outdoor-friendly?
Although Boston fern is frequently grown as a houseplant, it also does well in USDA zones 9 to 11 outdoors in warm, humid regions. The plant could be able to endure dry climates if there is enough rainfall. The fern may be completely destroyed by the frost, but it will recover in the spring.
Boston fern needs filtered light or partial to complete shade in gardens. Because few other plants will thrive there, the plant is a fantastic choice for wet, dark places because it adds a splash of vibrant color.
Rich, organic soil is what the plant favors. Dig in a few inches (8 cm) of compost, finely chopped bark, or leaf mulch if your garden soil is poor.
Can I plant the fern I have in a planter outside?
The majority of fern cultivars have similar planting requirements, although others only grow well in specific environments or under specific lighting conditions. Make sure to research the planting requirements and appropriate USDA hardiness zones for your particular type of fern before using these instructions as a guide.
- 1. Based on your climate zone, select a planting season. The ideal time to plant ferns is typically in the early spring following the last frost, although you can still do so without much difficulty in the summer. In milder regions, ferns can even be grown year-round.
- 2. Pick a shaded area. Most ferns grow in settings of moderate to complete shade. Make sure your particular fern gets additional water to make up for the heat if it can endure partial sun.
- 3. Use wet, slightly acidic soil to plant ferns. Since most ferns grow in damp woods or along the banks of water sources in their natural habitats, they typically need highly moist soil. Even fern kinds that develop drought tolerance usually need moist soil when they are first planted.
- 4. Add organic compost to your soil to enrich it. Apply a thin layer of organic compost to the soil’s top eight to ten inches, then mix it in using a gardening instrument. Your fern’s growth will be sped up by rich soil.
- 5. Plant the ferns. Make a hole twice as broad and as deep as the fern’s rootball. Place your young fern in the planting hole after gently removing it from its pot so as not to damage its roots. Soil is added to the hole. Ferns should be at least two feet away from one another.
- 6. Cover your soil with a two-inch layer of mulch. A layer of organic mulch, such as pine bark or leaf mold, will keep the soil moist, maintain a cool temperature, and prevent weeds from growing.
When are potted ferns permitted outside?
Hardy ferns are typically resilient. Many people can endure extremes of heat and cold. Hardy ferns will likely survive outdoors in whatever conditions your climate throws at you if you live in any of the USDA zones 2 through 9. Hardy ferns can endure temperatures as low as minus 50 degrees Fahrenheit, which is at the extreme end of the temperature range. But hardy ferns in USDA zones 2 through 6 typically have a semi-evergreen appearance. Many hardy ferns may typically be left outside throughout the winter without risk. However, some only survive the winter in USDA zones 6 or 7. In such situation, they can only be left outside safely in USDA zones 6 and 7, respectively, at 5 below zero and zero degrees Fahrenheit.
Below USDA zone 10, which has average maximum low temperatures that are slightly above freezing, the majority of tropical ferns are not cold-hardy. When exposed to freezing conditions for an extended period of time, many tropical plants perish. It’s likely that a tropical fern you have in a pot won’t survive if winter lows fall below freezing. If so, you can either relocate the pot inside, cover it outside, or let the fern wither before replacing it with a hardy fern the following year.
- Ferns make beautiful greenery.
- Hardy ferns are those that can survive in temperatures that are near freezing or lower; tropical ferns, on the other hand, cannot.
Is it possible to grow ferns outside?
Ferns are exceedingly forgiving and have a powerful sense of survival. Ferns can grow in areas where other plants cannot, and the majority flourish in rich, well-drained soil that is rich in organic matter.
The only maintenance needed when growing ferns outside is routine mulching and watering during really dry spells.
Except for the passing slug, which will eat almost anything, ferns are rarely bothered by pests.
Outdoor fern maintenance is so simple that you frequently overlook their presence. They are great for naturalizing and will continually please the gardener with their lovely texture.
How are ferns maintained outside?
Ferns are not permitted on my front porch. That’s difficult for a native Southerner like me to say. A common feature of the Southern countryside is a porch surrounded by ferns.
You better believe our shady back patio is covered in the lush green fronds, whereas our front porch faces straight South and a lovely Boston Fern can’t handle the intense heat of the midday sun! If given the right care, ferns are surprisingly simple to grow and maintain.
Select The Right Fern
The most preferred ferns for porches are Boston and Kimberly Queen ferns. The type of fern you buy should depend on the style you want.
Because of their gently weeping characteristics and vivid green fronds, Boston ferns look fantastic in hanging baskets and on plant stands. Kimberly Queen Ferns are ideal in pots flanking a pathway or entry since they have more firm, upright fronds.
Water Your Fern Regularly
Water is good for ferns. Remember that a rainforest’s gloomy, damp canopy is where they live in the wild. To keep a lush, healthy glow, soil must be consistently and uniformly hydrated.
How you plant your fern will determine how often you water it. Please keep in mind that ferns can dry out very fast if you decide to put them in a hanging basket or pot. Keep the soil moist but not dripping wet. To find out how often you need water your ferns, check them every day at first.
Follow These Overwinter Steps
Ferns are tropical plants, hence they cannot survive in cold weather. Try to overwinter your fern by trimming it back in the fall and putting it in a bright spot indoors to preserve its evergreen hue.
An effort at overwintering needs a certain location, a certain amount of humidity, and water. Keep in mind that even ferns that are dormant enjoy moisture, and a hot home can quickly dry out a plant. Throughout the winter, give your plant a few nice soaks in the shower.
How should indoor ferns be cared for over the winter?
A few straightforward guidelines will go a long way toward ensuring your plants stay robust and healthy when it comes to effectively overwintering ferns. And what’s most crucial of all? Before the first frost, bring them indoors!
Bringing Ferns Indoors Early
Ferns can tolerate chilly temperatures, but if they are exposed to a frost, they are vulnerable to injury. Frost can stunt and harm a fern’s roots in addition to killing off the leaf. And what happens if it is exposed to a hard freeze? It most certainly won’t be going to a second year of growth, but rather to the compost bin.
If an early season freeze or frost is forecast, move your fern to a partially covered area. The best options are a garage, shed, or barn. If that is not an option, cover it with a blanket or sheet at the very least. The most important thing is to keep it safe from harm until you can get it ready for indoor use.
Given that chilly weather is predicted, why not simply bring it inside? As you will see below, taking the effort to get your fern ready with a few quick actions will keep the plant and your house healthy!
Hose Down The PlantBringing Ferns Indoors
Use an outdoor hose to liberally wash your fern’s entire foliage before bringing it inside. Lift the fronds up when spraying so that you can also reach the underside of the leaves.
To get rid of any and all insects and pests that might be dwelling in your plant, do this immediately. Keep in mind that your ferns have spent the entire summer outdoors. And anything from a bird’s nest to aphids, spiders, and moths could be hiding beneath its leaf.
Spraying them down will help hydrate the plant in addition to keeping out unwanted house visitors. Before taking your plant inside, give it a little shaping after it has dried off a bit.
Pruning FernsBringing Ferns Indoors For Winter
Ferns can experience rapid growth in hot, dry summers. Spend some time shearing back some of the extra growth before bringing indoors. For this job, a good set of hedge shears are ideal.
Heavy pruning is not necessary. Cut back any long stragglers that are making it tough to place inside to start. Finish by giving the plant a little trim. Be sure to remove any fronds that can cause a problem if you place the plant on a stand or table.
Re-Pot Root Bound Plants
Watering a potted plant might become difficult if the roots become overgrown. Ferns can also suffer swiftly from being root-bound, and they are not an exception.
Check to check if your fern’s roots have completely filled the pot. It’s time to act if there isn’t much dirt left or if the roots have completely encircled the pot’s sides.
Replanting ferns in a new pot that is one-quarter to one-third larger than its last container is a reasonable general rule of thumb. When repotting, use premium, light potting soil. Don’t give ferns too much fresh area; resist the urge to do so.
A fern’s roots will become too soaked if it is kept in containers with too much soil surrounding them. Simply put, too much soil absorbs moisture, which makes it difficult for the plant to grow. There is absolutely no need to fertilize. Ferns don’t need a lot to function well. In actuality, a fern will have more problems from too many nutrients than from not enough.
Dividing Overgrown FernsBringing Ferns Indoors
You can choose to divide ferns that have grown too big for re-potting into new beginnings. Actually, this is a fantastic strategy to grow even more exquisite, lush, green, and shade-loving plants for your outdoor space the next year!
Use a cutting instrument or sharp knife to split a fern into portions to produce new plants. The majority of large ferns can be divided into four separate plants by quartering the original plant.
Fern roots are quite resilient and accepting of this procedure. The majority of the plants will adapt to their new circumstances quickly as long as they are replanted into a high-quality, light potting mix. Check out our article on how to divide ferns in the fall for more information on the topic.
Lighting
Your plants are now prepared for indoor use! Ferns do not require direct sunlight or intense lighting to survive during the winter. In actuality, a fern might suffer more harm than good from too much sun.
Ferns will thrive in circumstances with moderate, indirect lighting. This might be in a room’s corner that gets natural light from a neighboring window or in a chilly basement with indirect illumination from a basement well-widow.
One thing you should do is keep your fern away from a window with a southern exposure. In fact, the heat and rays of the sun that enter through the glass might burn the vegetation. Although windows that don’t face the south can be beneficial for ferns, indirect lighting that is a little bit distant from any window is always the best option.
Only water your ferns in the winter when the soil is absolutely dry. Overwatering is worse for ferns than underwatering. Do not panic if your ferns drop a few leaves or lose a little color throughout the winter. In the spring, they will reappear in all their splendor.
Plants should be removed when the weather warms up in the spring. Be sure to shield your ferns from late-spring freezes or frosts, just like you would in the fall. For more
Here’s to taking your ferns inside for the winter so you can save them to re-grow in the spring!
Are ferns in pots perennials?
With the right care, Boston ferns can be grown as perennials inside. This implies that you will continue to enjoy your plant for many years, if not decades.
Can ferns in pots endure the winter?
You may effectively overwinter ferns, allowing you to continue to enjoy them year after year, whether they are in your yard, a hanging pot, or a basket.
How long should ferns be left outside?
In warm regions, potted ferns—of which the most popular are sword varieties like the Boston fern (Nephrolepis exaltata “Bostoniensis”) and the Dallas fern (Nephrolepis exaltata “Dallas”)—can be left outside during chilly seasons. They actually favor temperatures below 60 degrees Fahrenheit at night and below 72 degrees Fahrenheit during the day. In U.S. Department of Agriculture plant hardiness zones 9 to 11, where temperatures rarely fall below 45 degrees Fahrenheit, they are regarded as perennials. However, they must be taken indoors if frost is imminent.
How do you winterize ferns in pots?
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.
