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 dots (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 plants from temperature fluctuations 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.
Are ferns suitable as outdoor plants?
Ferns add a tropical feel to any shade garden at home, whether you grow them as a groundcover or in a hanging basket. Ferns offer a simple method to add layers of green texture to your landscape as long as it is damp and shaded.
What place outside should I put ferns?
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 long do ferns last in the open air?
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.
Are ferns easy to maintain outside?
Generally speaking, ferns require less upkeep than other plants do. They really only require a small number of items, the majority of which are straightforward and make perfect sense given their natural environment.
Typically, ferns are found in forests. They flourish in bushes, beneath larger trees, and in the underbrush. As a result, they prefer some shade and don’t require a lot of light. Making sure your ferns have a lot of organic matter in their soil is vital because forest floors are generally covered in decaying leaves and wood.
Additionally, due to the shade provided by the trees, water does not evaporate as rapidly and is instead retained in the air and the rich, dense soil. Maintain a moderate to high humidity level, shelter, and a well-watered environment for your fern.
Do ferns reappear each year?
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.
How is a fern maintained outside?
Despite the fact that ferns exist in a variety of forms, dimensions, and textures, all ferns require a comparable level of maintenance. Ferns can be a lush and foliage-forward addition to landscaping if they are planted in the appropriate conditions.
Light: Ferns prefer a canopy of dappled shadow. Ferns will get overly stressed in dense shade or direct sunlight.
Watering: Watering will be required if there isn’t an inch of rain per week from nature, especially during the first growing season following transplanting.
Ferns’ thirsty roots bury themselves deep within friable, organically rich soil. Heavy clay soils need compost amendments to become friendly. Most ferns thrive in neutral or slightly acidic soil; strive for a pH of between 6.0 and 7.0.
Do ferns endure the winter?
Ferns come in a huge variety of varieties. Most can be classified as either evergreen or deciduous. For the winter, each will need slightly different maintenance. Regarding the care of either type, your gardening zone is also important.
Evergreen ferns may survive in temperatures as low as Zone 3. Others favor drier environments. The same is true of deciduous ferns, with several varieties suitable for various climate zones. In order to choose the finest winter care method to use, it is crucial for you to know what sort of fern you have and what zone you are in.
To receive the most precise information, use the USDA Hardiness Zone map if you are unsure of your hardiness zone. You can also search by location or city.
Evergreen Ferns
As long as they are grown in suitable zones, evergreen ferns retain their green color throughout the winter. In reality, its springtime green foliage will wither and fall off. In Zones 3 through 10, depending on the variety, they may flourish. These ferns are frequently used in floral arrangements to add the necessary greenery.
The Christmas fern is an illustration of an evergreen fern. In Zones 5 through 9, it thrives.
Making sure you have the appropriate fern for your gardening zone is all that is necessary to winterize evergreen ferns. Evergreen ferns can be pruned back in the spring when the old fronds start to appear scraggly and the new fronds are emerging if they are grown in the right climate. They will provide greens over the winter months. If watering is required to prevent drying out, make sure roots are kept moist by watering the ground rather than the fronds.
Deciduous Ferns
In the winter, deciduous ferns lose their green color. But if you’ve chosen ferns appropriate for your zone, they’ll still make through through the winter just fine. Cut back fronds when they begin to die in the fall. During the winter, ferns can be kept warm by being covered in mulch. In the spring, you’ll notice fresh fronds growing.
