Keeping Boston ferns alive in the winter can be difficult, but it is not impossible. The first step is to find a place inside your home that is brightly lit but not in direct sunlight, as they prefer indirect light.
The ideal temperature range should be between 60-75 degrees. If temperatures are too cold, this will cause the fern to go dormant and the leaves will turn brown. Water is also key in keeping your Boston fern alive in the winter.
Make sure to moisten the soil once a week, and allow it to several hours for the top layer to dry out before watering again. Mist the leaves with a spray bottle as often as you can to help maintain the humidity level.
Fertilizer is also essential in order for the Boston fern to continue growing and stay healthy. Use a balanced liquid fertilizer once every two to three weeks while they are actively growing. Finally, dust the leaves very lightly every now and then to keep them looking clean.
With a few adjustments to your winter routine, your Boston fern can thrive even in the colder months.
Can I leave my Boston fern outside in the winter?
No, you should not leave your Boston fern outside in the winter. Boston ferns are tropical plants which means they cannot tolerate freezing temperatures. Even if you live in a relatively mild climate, temperatures lower than 55°F can cause damage to the plant—especially if they remain in cold temperatures for an extended period of time.
If you want to keep your Boston fern through the winter, you should bring it indoors to a bright, warm location. You should also try to maintain humidity and mist the leaves every so often.
What is the lowest temperature a Boston fern can tolerate?
Boston ferns are among the most popular houseplants, known for their lush and exotic foliage. They thrive in humid environments, and prefer temperatures between 55-75°F (13-24°C). Although they are relatively hardy plants and can tolerate short periods of temperatures below 55°F (13°C), the lowest temperature a Boston fern can tolerate for extended periods of time is 45°F (7°C).
To keep your Boston fern in good health, you should keep your home’s temperature consistent and allow your fern to experience 2-3 hours of indirect sunlight during the day. Boston ferns prefer to have moist soil; they should be watered once a week, but the amount of water they need may vary depending on their environment.
During cooler months, you may need to water them more often and mist the leaves several times a week.
Will Boston ferns grow back after winter?
Yes, Boston ferns will typically grow back after winter. Boston ferns are a tropical plant that needs protection from cold temperatures and frost. During winter, you should move the fern into a more protected area of the home, such as a sunroom or close to a window where it can get enough light and warmth, but not be subject to harsh drafts.
Additionally, make sure to keep the soil evenly moist and fertilize your fern with a water-soluble fertilizer every 1-2 months throughout the growing season. If you follow these steps, your Boston fern should survive winter and grow back in the spring.
Will ferns survive winter in garage?
Ferns can survive the winter in a garage, but it’s important to consider the environmental conditions in the garage before attempting to overwinter them. Ferns prefer bright, indirect light for most of the day and temperatures on the cooler side (50°F–75°F) in winter.
It’s important that the garage has good air circulation and access to sunlight during the winter months. Be sure to check your garage temperatures regularly, ideally two to three times a day to ensure the ferns are not too cold or too hot.
If you need to provide additional lighting, 10-12 hours of fluorescent light from several feet away should be sufficient. As for moisture, keep the soil lightly moist but never soggy. Finally, make sure to keep an eye out for pests such as mealybugs and spider mites.
If you can provide these environmental conditions and regularly inspect for potential problems, ferns should be able to survive the winter in the garage.
How do you bring a fern back to life after winter?
Bringing a fern back to life after winter requires a few steps. First, carefully remove the fern from its winter location, making sure to check for any insects or diseases. Remove any dead or decaying fronds and discard these.
Prune off any dead leaves and stems. Then, give the fern a good watering and allow it to drain. Next, place the fern in a location which receives bright indirect sunlight, checking frequently to make sure the soil stays damp but not soggy.
Feed the fern by lightly sprinkling a slow-release fertilizer over the soil every 2-3 months. Finally, watch for any signs of new growth and continue to provide a regular watering and fertilizing schedule.
Is my fern dead or dormant?
If your fern appears to be wilting or browning, it’s likely dead. However, some varieties of ferns enter a period of dormancy during the winter which can cause them to look like they’re dying. Try to identify what kind of fern you have to determine if it’s just sleeping or is dead.
If it’s a tropical variety, then it is probably dead if you’re in an area with cold winter temperatures. On the other hand, if it’s a hardy variety, then it may just be dormant.
If you’re not sure, you can test it by gently tugging on a frond. If it resists, then it’s probably still alive. You should also gently check the soil to feel for moisture. If it’s dry and the frond does not pull off, then your fern is alive and just dormant.
You can help your fern out of dormancy by misting its leaves once or twice a week, increasing the humidity of the room it’s in, and avoiding repotting it until warmer weather returns. If it’s dead, there’s no saving it except by starting anew with a new fern and following recommended care instructions.
Can you revive a dried out fern?
Yes, you can revive a dried out fern. The trick to reviving a fern is to make sure that it gets enough water. This can be accomplished by increasing the amount of water you give the plant, but also by increasing the humidity in the area it is placed in.
You can do this by keeping the plant away from direct sources of heat and air conditioning. Additionally, misting the leaves of the plant with water or creating a humid microclimate around the fern, for instance on a tray filled with gravel and water, can help with restoring the humidity level your fern needs to thrive.
Another helpful tip is to fertilize the fertilizer fern with a diluted liquid fertilizer every 7-10 days. If these tips don’t help with reviving your fern, the plant may be beyond repair and it may be time to repot it with new soil.
What is too cold for Boston Ferns?
Boston Ferns typically do best in warmer, humid climates. They should be kept between 65-75° F (18-24° C) to stay healthy and grow strong. Too cold temperatures can cause Boston Ferns to suffer from leaf damage and brown fronds.
Winter temperatures below 50° F (10° C) can be particularly damaging to Boston Ferns. It is important to monitor the temperature and humidity of your Boston Fern’s environment to protect it from harm.
Additionally, Boston Ferns should not be exposed to high levels of direct light, as it may scorch the leaves and cause long-term damage. If you live in an area with cold winter temperatures, it is best to bring your Boston Fern indoors during the colder months.
This will protect it from potential leaf damage and frost.
Can Boston Ferns survive 35 degrees?
Boston Ferns generally thrive in temperatures between 65-80 degrees Fahrenheit and therefore 35 degrees may be too cold for optimal growth. While it is possible for a Boston Fern to survive 35 degrees, it might experience distress and possibly die in those temperatures.
In order to maintain the health of a Boston Fern when temperatures drop below 35 degrees, it is best to bring the plant indoors to a comfortable temperature range and make sure not to overwater it. Adding a humidifier or misting the leaves of the plant on a regular basis will also help it to tolerate lower temperatures and promote healthy growth.
Can ferns live in 40 degree weather?
Yes, ferns can generally survive in temperatures as low as 40 degrees Fahrenheit. However, they will thrive best in temperatures between 55 and 75 degrees. During colder temperatures, the fern leaves may begin to brown and curl up.
While most ferns can tolerate a one-time cold spell, it is important to ensure that temperatures do not get too low, as prolonged cold spells can cause the plant to die. Ferns also require a good amount of humidity, so if the air is too dry, you may need to mist them regularly.
Additionally, it is best to avoid direct sunlight and ensure that the fern is planted in rich, well-draining soil.
When should I bring my Boston fern inside?
When temperatures start to dip below 55°F (12.78°C), it’s time to bring your Boston fern indoors. Also, when dry indoor air starts to wreak havoc on your fern’s delicate foliage, it’s time to move it inside.
Take your cue from other plants in your area and watch for signs of drying or wilting as cooler temperatures and shorter days approach. Make sure you don’t wait too long to transfer your plant, or it may not survive the winter indoors.
To prepare for cold winter months, stop fertilizing your fern two months before that and provide it with bright, indirect light and regular misting. Lastly, inspect carefully for signs of pests before you bring your fern in, as bringing any pests inside with your fern will spread them to other plants in your home.
How cold is too cold for ferns?
Ferns vary in their tolerance to cold temperatures and are generally tough plants that are able to survive lower temperatures than many other plants. In general, ferns should not be exposed to temperatures below 10 degrees Fahrenheit for long periods of time as this could cause permanent damage.
If temperatures drop lower than 10 degrees Fahrenheit, ferns should be brought indoors and should not be exposed to temperatures below 0 degrees Fahrenheit for any period of time. In most cases, any temperature below freezing is too cold for ferns.
It is important to consider the type of fern you have, as certain species may tolerate slightly colder temperatures than others.
Can Boston ferns be cut back in the fall?
Yes, Boston ferns can be cut back in the fall, but only as a last resort if they have been severely damaged or become unattractive due to disease or pests. Brown or dead fronds may be removed at this time, but they should not be extensively cut back.
Many gardeners opt to prune Boston ferns in the early spring, as this provides better opportunities for regeneration since the new growth has a full growing season to establish before the onset of winter.
Additionally, late-season pruning produces less vigorous new growth which can make the fern more vulnerable to winter damage.
Should I cut ferns in fall?
The answer to whether or not to cut ferns in the fall largely depends on two factors: your climate and which type of fern you have. In cooler climates, the onset of cold temperatures can cause the fern fronds to die back and a trim-back can be beneficial.
Doing this will also reduce the size of the plant and make it easier to protect it during winter months.
On the other hand, in warmer climates where temperatures remain mild during the autumn season, you may want to wait until later in the year before pruning your ferns. Depending on the type of fern, its primary growing season can last 3-4 months and it may be beneficial for the fern to go through that entire cycle.
In general, if you have a smaller fern or a species that does not go dormant, it is best to prune it in the fall. However, for larger ferns, it is best to wait until their growing season has ended and they begin to go dormant to ensure that the new growth will be protected during the colder months.
Ultimately, it’s best to consult with a local nursery or your local extension office prior to pruning to ensure you make the right decision for your ferns.
Do ferns grow back if you cut them?
Yes, ferns will grow back if you cut them. In order for this to happen, the cut should be made at a node, which is the point of connection between the leaves and the stems. Typically, when a node is cut, the fern will begin to send out new shoots from that point, which will eventually develop into two new vines.
It is important to keep the cuttings hydrated and in an environment that has adequate moisture and humidity in order for successful regrowth to occur. If the cuttings are re-planted in a soil, they should be planted at a minimum of two inches deep and two to three inches away from each other.
Once planted, the ferns should be given regular watering and fertilizer if needed. With proper care, the cuttings will begin to grow, and in time, you will be able to enjoy your ferns in full, healthy glory.
Can you cut ferns all the way back?
Yes, you can cut ferns all the way back. Some fern varieties, such as the delicate bracken fern, need to be trimmed back once a year in springtime to keep them from becoming overgrown and unsightly. The best time to trim ferns back is in early spring, before the new shoots have had a chance to emerge.
This will give the fern time to regrow and fill out during the warmer months. To trim a fern all the way back, use pruning shears and remove all of the leaf fronds. Remove callous brown fronds first and then proceed to remove healthy fronds until you reach a desired look.
When finished, the fern should look open, with room for new growth. After trimming, it is important to keep the soil moist and fertilize the plant to help it regrow quickly.
How long do Boston ferns live?
Boston ferns, or Nephrolepis exaltata, generally live for 8 – 10 years or longer when provided with the correct conditions and given adequate care. These hardy perennial ferns have been known to live for up to 20 years.
To maximize their lifespan, Boston ferns should be provided with bright, indirect sunlight and kept in a humid environment with temperatures of between 65 and 75°F (18 – 24°C). Their soil should be kept consistently moist but not soggy.
Additionally, it’s important to occasionally trim off dead, brown fronds and provide them with regular fertilizer and misting to keep them looking full and healthy. With the correct care, Boston ferns can be a beautiful, long lasting addition to your home or garden.
