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.
What time may I move my fern 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.
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.
Can ferns in pots remain outside in the winter?
If you transfer ferns that were grown in outside planters indoors, they may survive the bitterly cold winter. Nephrolepis exaltata “Bostoniensis,” popularly known as the sword fern, is a fern that thrives in USDA plant hardiness zones 10 through 11, and its thicker rather than airy foliage is ideal for the practice.
Give your fern a moderate amount of indirect light indoors, no more fertilizer, and a little less water than you would during the outside growing season. Most ferns enjoy wetness, but not when there is water in the saucer of the pot. Do not let the soil dry out completely and water plants frequently. When nighttime temperatures are over 50 degrees Fahrenheit, move the plant back outside.
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!
Can ferns in pots be buried in the ground?
Large, striking outdoor ferns provide porches, decks, and terraces personality and charm. These low-maintenance plants are perfect for sheltered areas because they thrive in low light. Use outdoor ferns in planters, urns, window boxes, hanging baskets, and more. Here is a short guide to assist you in choosing some of the top outdoor ferns.
The Boston fern was initially “found in a consignment of plants delivered to Boston in the 1800s.” It is a native of Florida, Mexico, and Central America (and thus it earned its common name). Because it could thrive in the chilly, dark climate of Victorian sitting rooms, this attractive plant quickly gained popularity. Boston fern became popular because to its lovely, arching fronds and rich, green hue. Boston fern continues to be a popular choice for both indoor and outdoor settings today. However, Boston fern is frequently a superior option for outdoor settings because it may reach heights and widths of 3 feet. Boston ferns can be grown directly in the ground in zones 9 through 11.
This plant certainly lives up to its name. This hardy fern may get up to 6 feet tall and broad, making it a far better choice for your porch or patio than the typical Boston fern would be for your front parlor. Long, arched branches with broad, deep-green fronds are characteristic of macho ferns. Macho fern can be grown in enormous hanging baskets, as well as in oversized urns, pots, or tubs. From zones 9 to 11, macho ferns can be successfully cultivated in the ground.
Considering their enormous size, macho ferns typically look their best on their own. Smaller plants in container gardens can be sucked up by them.
If you want to keep this tropical fern for the winter, you can bring it indoors as a sizable houseplant. Find out how to protect your favorite tropical plants in time for winter.
Check out the magnificent Kimberly Queen fern if you enjoy ferns but frequently forget to water them. These strikingly beautiful plants of Australia can withstand a little bit more heat, drought, and sun than other outdoor ferns. The magnificent upright tendencies of Kimberly Queen ferns make them excellent candidates for urns or other vertical containers. The plants expand to a height and width of three feet, and each leaf’s underside develops attractive spots (spores). Zones 9 to 11 are suitable for growing Kimberly Queen fern in gardens.
Boston fern is a more conventional choice for lovely hanging baskets; Kimberly Queen fern is more suited to urns, container gardens, and window boxes due to its erect nature. Kimberly Queen fern can be brought indoors as a houseplant, similar to Boston fern and macho fern, to protect it over the winter.
In addition to tropical ornamental ferns like Boston, Macho, and Kimberly Queen, you can grow a variety of perennial ferns in your flower border or landscape. The majority of these plants are winter-hardy and reappear every year bigger and better. Hardy ferns consist of:
purchasing ferns Look for full, balanced plants with rich, brilliant foliage when buying ferns to decorate your deck, patio, porch, or balcony or to plant outside in your garden. Many ferns will have gray-green or olive-green leaf instead of their customary bright green color, especially fragile kinds like Boston, Macho, and Kimberly Queen. When too dry, most plants quickly recover when watered.
To determine whether ferns are suitable for hanging baskets, search for plants that are not rootbound. The hanging basket will dry out more quickly the more roots there are in the pot. Ferns can occasionally get fairly rootbound, especially toward the conclusion of the growing season. When squeezed up against one another, lopsided ferns frequently break and bend and are sold in stores. However, don’t let this discourage you; with the right care (see the instructions below), your ferns will recover rapidly.
Remember that perennial ferns slumber over the winter when buying them. Early spring sales of perennial ferns might not have much new growth on them. If you want to make a statement in your yard the first year, pick the biggest plants you can find because they grow a little slower than tropical ferns. Growth rates differ among various fern species. For instance, the Japanese painted fern grows slowly, whereas the joyful ostrich fern grows quickly.

No matter if they are tropical or hardy, ferns love to grow in areas that are shaded or partially shaded and have rich, slightly moist soil that is full of organic matter (such as compost). Additionally, they appreciate high humidity levels and the occasional shower. Use a slow-release granular fertilizer to feed the ferns. If cold weather is expected, transfer tropical ferns to a protected area because they are sensitive to frost. After planting, topdress the soil with a few inches of compost to give your ferns the best possible start. Then apply mulch to ferns to shield them from temperature extremes and stop weed competition.
Because containers, especially hanging baskets, dry up a little quicker than the ground, ferns in pots require more frequent watering than their counterparts in the ground. Potted ferns may require daily watering to prevent drying out when the weather is particularly hot, dry, and windy. However, to prevent overwatering your ferns, always check the soil’s moisture level before you water.
