How to Water Boston fern?

The soil of boston fern should be kept moist and aerated throughout the growing season. However, do not overwater as the root system is very sensitive to soggy substrate and plant’s leaves might wilt. Rainwater is perfect, but tap water is also acceptable as long as it is kept for a while on a room temperature. During the warm weather, the plant can be watered several times a week. During the winter, the watering regime should be less frequent. This means that the plant should be watered when the top part of the soil has dried out, in order to imitate natural conditions for dormancy.
Apart from ample watering, boston fern requires ample air humidity. It will grow in less humid location, but will likely not develop lush and green leaves. This means that this is the perfect plant for your bathroom and/or our kitchen. On occasion, water spray to increase the humidity levels.

What should I do if I water my Boston fern too much or too little?
Overwatered Boston fern
Despite how much it loves water, it is possible to overwater the Boston fern. This is most likely to happen if you leave your plant sitting in a pool of water or use a planter that doesn’t have drainage holes. Either of those conditions will be too wet and will prevent the roots from being able to take up nutrients and moisture. Too much moisture in the soil can also allow fungal or bacterial diseases to develop.
Wilted and yellow leaves are the initial symptoms of overwatering. Over time, the stems may droop and fall over, or begin to feel soft and mushy. However, be sure to check for other causes if you suspect your Boston fern is overwatered, since other issues can look similar and it’s difficult to give this plant too much water.
Underwatered Boston fern
Vigilance is required to keep this plant wet enough, unless you’re using a self-watering planter, meaning that many fern owners inadvertently let their plant get too dry now and then. In dry conditions, this plant can change in appearance seemingly overnight, from lush and green to brown and crispy.
In extreme cases, the plant may dry up so thoroughly that it seems there are no living fronds left. But it may still be possible to save the plant if some of the roots are still healthy. Cut off all of the dry and dead stems, then water thoroughly and return the plant to its usual location. Unless the roots are all dead, this plant can be surprisingly resilient and start putting out new fronds. It may take several months to grow back to the size it was before, but this is possible if you provide proper care in that time.

How can I water my Boston fern properly?
Your Boston fern prefers consistently moist soil that mimics its native enironment, which could mean watering as often as every one or two days. This is a plant that should not be allowed to dry out. Once the top layer of soil begins to feel even slightly dry, it’s time to water again. And don’t just give it a few drops of water: soak the soil completely until water drains out from the bottom of the pot. After the excess water has drained out, dump it so the pot isn’t sitting in a puddle. This is the best method to ensure that soil never gets too dry.
Read More more
What should I consider when watering my Boston fern?
The amount of humidity in the air around your Boston fern will influence how often you need to water it. Higher humidity in the air means less frequent watering, as evaporation is slower. Keeping this plant near a heating or cooling vent will cause it to dry out quickly, so choose a location that is protected from any type of draft. They prefer dappled and indirect sunlight and temperatures between 55-80 degrees F (13-27 degrees C) meaning that keeping these ferns in a warm and sunny spot windowsill could cause them to get dehydrated quickly.
Rainwater or distilled water is great for this plant if you have access to it, although tap water in most places also works fine. Certain minerals and chemicals in tap water can cause brown leaf tips, especially since Boston fern has very thin and delicate leaves.
Small pots can cause issues for Boston fern , because they only hold a small amount of potting medium and can dry out more quickly. It is best to allow this plant more space in the pot than many other houseplants.
Consider using a self-watering planter for Boston fern. This type of pot uses a wicking system that allows the soil to continuously soak up water from a central reservoir, meaning that the moisture level in the soil stays consistently moist. Not only does this type of pot keep you from having to constantly water your fern, but it is also quite beneficial for the roots to have a constant supply of water instead of going from dry to wet and then back again.

Cultivation:FertilizerDetail

How to Fertilize Boston fern?

Boston fern will appreciate additional nourishment, however, fertilizing will depend from the age and soil type of your plant. Generally, recently potted plants do not really require any additional nourishment. As the plant grows and gets repotted, additional nourishment should be added. Using a general all-purpose fertiliser (liquid or slow-release pellets) which contains roughly equal proportions of the three main elements (N%-P2O5%-K2O%) with 20-10-20 would do the trick. If your boston fern is grown on a humus or turf-based rich substrates, you should fertilize it once a month; on sandy-loamy substrates, apply fertilizer twice a month.

Fertilizer

Often found growing in tropical shade gardens Boston fern is an attractive addition to the area. It serves as an anchor plant and adds texture. Best of all, it requires little care beyond watering and occasional feeding. So, when do you fertilize Boston fern, and is there a best time? Like most garden and contain plants, Boston fern does have a few requirements to keep it healthy and thriving.
Why you need to fertilize Boston fern is pretty simple. Your plant needs the extra nutrients to produce healthy new growth. The additional nutrients also support the health of old growth and can help your plant fight off diseases and pests.
Where Boston fern is growing determines its feeding schedule. It is not a particularly hungry plant but does require some additional nutrients. Outdoor plants require fertilizing once in the spring, while indoor specimens need a monthly feeding starting in the spring and continuing through the summer.
You have a few options when choosing a fertilizer for Boston fern. It also depends on if the plant is growing indoors or in the garden. Outdoor plants will thrive with a layer of mulch or compost. For indoor plants,an ideal fertilizer will have an N-P-K ratio of 3-1-2. However, a general-purpose fertilizer that has an even blend of nutrients can work well in some cases. Still, even when using a balanced fertilizer, the ratio number representing the volume of each nutrient should be at 3 or lower.
Fertilizing Boston fern isn’t difficult, but it will depend on where the plant is growing. Outdoor garden plants do best when a layer of mulch or compost is added to the soil. Make sure the organic material is around the base of the plant. Indoor plants typically thrive with a diluted liquid fertilizer applied before watering, monthly in the spring and summer.
You want to remember Boston fern is a slow feeder. It does not require a lot of extra nutrients, especially nitrogen. While fertilizer does help support health growth, too much can burn the plant’s sensitive root system.
Do not fertilize after the early autumn, which can cause too much growth just before winter. Also, Boston fern should not be fertilized during hot and dry times of year, since dry soil does not deliver fertilizer as effectively as moist soil. Fertilizing at this time can also stimulate growth which in turn needs more water that may not be available. It is best to keep fertilizer for earlier in the season when temperatures are cooler. Finally, remember that Boston fern can absorb fertilizer that has been applied to nearby plants or lawns, so be cautious about inadvertently giving ferns a double-dose of fertilizer.

What Are the Sunlight Requirements for Boston fern?

Boston fern grows on forest floor and does not tolerate well bright sunlight. It should thus be placed in a bright position if kept as a house plant, without being exposed to direct sunlight except during the winter months. A perfect position is to be placed on a window facing the rising or setting sun. In this way, the plant will be protected from the midday sun, which can be the most damaging.
Cultivation:SunlightDetail

Know the light your plants really get.

Find the best spots for them to optimize their health, simply using your phone.
What type of sunlight does Boston fern need?
Boston fern should receive a small amount of indirect light each day. Filtered light from a tree canopy often provides the best growing conditions. Typically, three hours of daily light exposure represents the maximum for this plant. When the Boston fern gains exposure to either too much light, more than three hours per day, or light that is too direct, it will likely burn, dry out, and die.
Read More more
Does Boston fern need to avoid sun exposure? / Should I protect Boston fern from the sun?
At all times, you should avoid giving your Boston fern too much sun exposure. Likewise, you should also refrain from moving your Boston fern into direct sunlight very suddenly. Most of Boston fern are more tolerant of morning and afternoon sunlight than midday sunlight as midday sunlight is the hottest, most direct, and most capable of harming your Boston fern quickly.
Likewise, if you grow your Boston fern indoors, you should not allow it to sit where it can receive direct light from a window. When growing indoors, choose a place that receives a small amount of indirect light each day, just as you would when growing outdoors. Finding the correct amount of sun exposure from the start, whether grown indoors or out, is ideal. However, if you find your Boston fern is receiving too much light, you should move its container immediately, or, if your Boston fern grows in the ground, find a more shaded area to transplant it.
Read More more
What will happen if Boston fern gets inadequate sunlight?
While the Boston fern requires very little light compared to most other plants, it still needs a few hours of light to put forth healthy growth. Without those few hours of indirect light, the Boston fern may begin to lose its foliage color and can exhibit stunted growth. However, since Boston fern is so fond of shady conditions, it is rarer for it to suffer from lack of sunlight than it is for it to suffer from too much.
Read More more
Does Boston fern need special care about sunlight during its different growth stages?
Generally, the low light needs of Boston fern will remain the same throughout the entirety of its life span. However, the one exception to that is when this plant is young. While the Boston fern at any growth stage is vulnerable to damage from excessive or sudden direct light, the Boston fern that is younger is even more vulnerable. The same is true for any Boston fern that has been recently transplanted to a new growing location and has not yet had the chance to establish itself.
Read More more
How much/long should Boston fern get sunlight per day to grow healthily?
For the healthiest growth, Boston fern should receive about three hours of indirect light per day or less. You can consider any amount of light beyond three hours to be too much for this shade-loving plant group. Boston fern thrives naturally in the forest understory, which is why they can conduct photosynthesis with quite low volumes of daily sunlight.

How to Prune Boston fern?

If your boston fern starts to exhibit old, discoloured or sick leaves, it will require some pruning in order to maintain its best and healthiest form. This can often happen as new growth shades older leaves. Also, damaged leaves should be removed as to keep the aesthetics and the overall health of the plant. Ideal time for trimming old leaves is during replanting, but if needed, it can be pruned in spring or summer. Always use clean, sharp tools. When removing the leaves, do not cut the top of the plant and instead prune the side leaves. Remove them as close to the base as possible as to ensure the space for the new growth. Wilted leaves should be trimmed down roughly 5 cm toward the base. Wear garden gloves and to disinfect your pruning tools between the cuts to minimize the risks of contamination.
Cultivation:PruningDetail
How can I prune my Boston fern?
Pruning your Boston fern is a fairly simple process. First, you will need a reliable set of hand pruners or hedge trimmers. You may use a clean pair of sharp scissors if you don’t have pruners or garden shears on hand. It’s important to always clean your gardening tools before and after using them to prevent the possibility of spreading disease or infection to other plants. To prune your Boston fern simply allow your plant to go dormant over the Winter. Some time between late winter and early spring – or when new growth starts to appear – take your clean pruners or trimmers and cut away any dying, damaged, yellow or declining foliage. Repeat this process until you reach the base of the plant or until there are no dead pieces left to cut. When pruning, be careful not to damage the new growth that may be emerging near the base of your plant. These parts cannot be restored and pruning can increase the ventilation of the plants and facilitate their growth. Any pruning that is done to this plant should be cut straight across the blades or stems. No angled cuts are required. Diseased leaf blade foliage can be removed as it appears. This could be done anytime when your Boston fern is growing.

What should I do after pruning my Boston fern?
Once you’ve pruned your plant, you should dispose of the stems and leaves either by composting the healthy ones or throwing out the diseased parts. You can also fertilize just before or after pruning, which gives Boston fern a little vitamin boost that can provide it the nutrients needed to better protect itself from any nearby pathogens or diseases. Do not water the Boston fern immediately after pruning as this can lead to fungal infestation of the plants through the wounds. You don’t need much after care when you’re done pruning. It might benefit from light watering and some liquid plant food to encourage new growth.

How can I prune my Boston fern during different seasons?
Early spring and late winter are the best times to prune your Boston fern on a large scale. If you want to control the size of your Boston fern, you can prune them as you wish, but be careful not to prune more than a third of the size of the plant. Yellow and diseased leaves may appear during the summer months when the Boston fern is growing vigorously and these types of leaves need to be pruned back immediately. These parts of the Boston fern cannot be restored and pruning increases the ventilation of the plant and facilitates its growth.
Read More more
When should I prune my Boston fern through different stages of growth?
Strategic pruning is usually done at different times of the year or during certain stages of growth depending on the plant. However, knowing when to prune your Boston fern depends on where you live and how established your plant is. For example, if your Boston fern is a new resident, it’s a good idea to wait until the plant starts to grow back before you start pruning. On the other hand, if your plant is already established, you will want to prune the dry or dead parts in plant before new leafy growth appears in early spring or late winter. This is the time of year when plants are dormant and pruning causes the least damage to them. This is also the best time of year to do more extensive pruning. It’s important to note that if Boston fern is pruned too late in the season, it can leave new growth at risk for damage or disease. However, if your Boston fern is indoors this is not a problem and you can prune at any time. Since this can affect the long-term health and appearance of your plant, it’s important to keep this in mind when deciding when and how to prune. As your Boston fern grows larger over time, you can trim it as needed after annual pruning. Dead, damaged, or diseased leaf blade foliage can be removed as it appears. This could be done anytime when your Boston fern is growing.

What is the Ideal Temperature Range for Boston fern?

Boston fern is native to warmer regions and likes increased temperatures. It can grow on temperature between 16 to 27 ℃, but will be able to survive for a shorter time periods in colder temperatures (down to 10 ℃). However, it will grow the happiest at room temperature (21 ℃). It also requires a constant regime of slightly elevated humidity of both air and soil.
Cultivation:WaterAndHardinessDetail
What is the optimal temperature for Boston fern?
For this tropical plant to thrive, you’ll want to keep them between 75℉ and 90℉ (25-32℃). Each species can handle temperatures outside of this range, but keeping it within several degrees of these limits will ensure they grow to their maximum potential.
As for its extreme temperature limits, any environment below 50℉ (10℃) or above 95℉ (35℃) will begin to hinder its growth and cause various aberrations to its leaves and stems. This is especially true with low temperatures; even a light frost can cause your tropical plants to perish. Cellular death can begin to happen at a rapid pace, with some species dying in as little as 12 to 24 hours.
Read More more
Does Boston fern require different temperatures for different growing phases?
While Boston fern doesn’t require any changes in temperature to enter different growing phases, it is important to stay consistent. Wild temperature fluctuations can slow down its growth regardless of its current phase, so it's always better to keep them in a controlled environment. That optimal temperature range of 75℉ and 90℉ (25-32℃) is vital to maintain, especially staying above the lower limit. Going above 90℉(32℃) isn’t ideal, but as tropical plant it won’t suffer too much. On the other hand, going below 50℉ (10℃) (and especially 40℉/5℃) will begin to directly damage this heat-loving plant species.
Read More more
Does Boston fern need different temperatures for different seasons?
Boston fern does not need different temperatures for different growing seasons. The most important step in seasonal care is to keep the environment within the optimal temperature range. That's why it's always best to keep this plant indoors. That way, you can control the temperature no matter what the climate is like outside.
Light is also important for tropical species, with all of these plants preferring a partial side level of sun exposure. This means any light they receive needs to be dappled or filtered, with bright but indirect light being the best option when growing your plants indoors. Too much direct sunlight can negatively affect your plant’s leaves, reducing its growth potential.
Read More more
What are the temperature guidelines to keep your Boston fern healthy?
Tip #1: Don’t Leave Your Plant Near Windows in Colder Months
If you want to make sure your plant isn’t exposed to colder temperatures, you may want to keep them away from windows. In colder months like late fall and winter, even the smallest draft can leak cold air into your home through cracks in your windows. While this air usually dissipates and warms up as it travels throughout your home, any plants placed in close proximity to the window will be affected. Move your tropical plants into an area where they will still get bright but indirect light, while making sure they won’t be affected by potential drafts.
Tip #2: If You Find Dry Patches, Your Plant May Be Getting Too Much Sunlight or Heat
You may notice the leaves become white or even scorched on a sunny day. These discolorations and unusual markings usually indicate that a plant is getting too much heat or sunlight, and it may be dehydrated. Excess light and heat will dry out the soil, stopping plants from getting the moisture they need to support their cellular structure. It also slows down or stops the process of photosynthesis, further hindering growth. If ignored for too long, these dry spots can spread and eventually result in the death of your plants.
Tip #3: Avoid Frost at All Costs
Colder temperatures and frost can damage your plants by causing ice crystals or disrupt normal physiological activity. This makes it nearly impossible for water to move freely throughout plant tissue, creating a deficit of moisture in their stems and leaves. You can tell a plant has been damaged by frost if it begins to suffer from hydrosis (it will appear as though it's soaked with water.) If the problem persists, your plants may begin shriveling and turning a dark brown or black hue. After that, the plant will almost certainly die.

What is the best way to maintain the right temperature for my Boston fern?
The best way to maintain the right temperature range for Boston fern is by keeping an eye on both the climate and humidity. You’ll want to try to keep each species in a room where you have access to climate control, keeping the heat in the temperature range best mimics its natural habitat. The humidity levels will also have a direct effect on temperature, so it's important to monitor these as well. You can artificially raise the humidity of your growing space by using a humidifier or lightly misting the leaves with water.
If you intend to grow this species outside, you may find it difficult to maintain the right balance of temperature and humidity. If temperatures begin to drop or the air becomes too dry, your best option is to find room within your home and move your plant inside. An indoor growing space will allow you to control the climate more closely, helping your plant reach its full potential.

What Soil is Best for Boston fern?

Boston fern requires a rich organic mixture soil that is well aerated and drained. This plant requires a lot of moisture, but is poorly tolerant to stand in water. You should make sure that the drainage is adequate as soggy soil might cause root rots to your boston fern. Soil should be slightly acidic (pH 5.0-5.5), medium rich with nutrients and rich in humus. A loamy mix of normal potting soil, compost and one third of turf should do the trick.
Cultivation:SoilDetail
Cultivation:PropagationDetail

How to Propagate Boston fern?

As boston fern does not produce flowers and seed, they can be propagated via spores and rhizome division. However, spores of cultivated breeds are usually sterile and will not sprout. Mature ferns will have more than one rosette-shaped vegetation point called funnels on the rhizome. A good time to propagate it is during the repotting, as not to needlessly extract and stress the plant several times. Just cut one of the funnels with a very sharp knife and plant both plant parts in separate containers. As always, remember to wear gloves and disinfect your tools.

Propagation

Boston fern provides a unique decoration for your garden and this plant is relatively easy to propagate. If you want to propagate more Boston fern, our article will show you the method. You can propagate this plant by division. You can divide your plants either during the spring or the fall. If you divide during the spring, you should do so earlier in the season to give your plant a better chance of adapting to the division before the summer heat arrives. The same is true during fall, as you should divide early enough to give your plant time to recover before the cold winter temperatures arrive. Dividing a plant is not difficult to do, but it is much easier to perform when you have the right tools available to you. Here is a basic list of what you’ll need:
  1. A digging shovel or a knife (preferable one with a pointed blade rather than a flat one)
  2. Diluted bleach solution or isopropyl alcohol to clean tools
  3. A water source (garden hose, watering can, etc.)
Steps: Step 1: Use your shovel to dig around the entire parent plant and lift it out of the ground. Step 2: Loosen and separate the main roots to have a better idea of where to divide the plant. Step 3:You can just pull the above-ground part of the plant to separate Boston fern if it is easier. If the root system is tightly wound, use your shovel or knife to slice down through the root ball to divide the plant into two parts. Repeat if you have a large plant you wish to divide more than once. Diluted bleach solution or isopropyl alcohol is required to sterilize the tools before use. Step 4: Wait for the wounds caused by plant division to dry, re-plant your parent plant in its original place. Transplant the divided portion to a new growing location.

How to Plant Boston fern?

Location is important so avoid direct sunlight. The plant will tolerate direct sun only in the mornings and evenings and during the winter time. Air humidity is required and it doesn’t tolerate drought. Also, to prevent excessive drying, the plant should not be positioned on a place of frequent drought.
When the plant’s root system overgrows the size of its current container, it should be repotted. You will detect this by gently pulling the root bale out of the pot. If it is overcrowded or whitish root fibrils (tiny light, root-like hairs) are visible on the outer edge of the bale, the plant should be repotted. The repotting should be done in spring. Carefully remove as much of the previous substrate from the root system, fill the new container up to half with the new soil and place the plant in the pot. Afterwards, fill up the empty space around the plant with the rest of the soil. Water generously at the end.

Underwatering
Underwatering Underwatering
Underwatering
Leaves may wilt for a variety of reasons.
Solutions: The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with. Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock. In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.
Aged yellow and dry

Natural aging can cause leaves to turn yellow and dry out.
Solutions: If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.

Underwatering
Leaves may wilt for a variety of reasons.
Overview
Overview
Underwatering plants is one of the quickest ways to kill them. This is something that most gardeners are well aware of. Unfortunately, knowing exactly how much water a plant needs can be tricky, especially considering that underwatering and overwatering present similar symptoms in plants.
Therefore, it’s important to be vigilant and attentive to each plants’ individual needs.
Symptom Analysis
Symptom Analysis
As mentioned earlier, overwatering and underwatering present similar symptoms in plants. These symptoms include poor growth, wilted leaves, defoliation, and brown leaf tips or margins. Ultimately, both underwatering and overwatering can lead to the death of a plant.
The easiest way to determine whether a plant has too much water or too little is to look at the leaves. If underwatering is the culprit, the leaves will look brown and crunchy, while if it’s overwatering, they will appear yellow or a pale green in color.
When this issue first begins, there may be no noticeable symptoms at all, particularly in hardy or drought-tolerant plants. However, they will begin to wilt once they start suffering from a lack of water. The edges of the plant’s leaves will become brown or curled. Soil pulling away from the edges of the planter is a telltale sign, or a crispy, brittle stem.
Prolonged underwatering can cause a plant’s growth to become stunted. The leaves might drop and the plant can be more susceptible to pest infestations, too.
Disease Cause
Disease Cause
Underwatering is caused by, quite simply, not watering plants often or deeply enough. There is a heightened risk of underwatering if any of these situations apply:
  • Extreme heat and dry weather (when growing outdoors)
  • Grow lights or indoor lighting that is too bright or intense for the type of plant
  • Using fast-draining growing media such as sand

Aged yellow and dry
plant poor
Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.

Name story

Boston swordfern
When you observed the leaves carefully, you will notice that the leaves are gradually getting narrow from the aerial root to the top, like a sword. So, it is called swordfern. As for Boston, it was shipped from Philadelphia in 1984 to Boston and that was when the plant started to transform. The straightened leaves become elegant, and because of the transportation, it is called Boston swordfern.

Common Problems

feedback
Feedback

The leaves of my boston fern is showing signs of discoloration, why is this happening?

more more
This is usually happening when there is wrong with the care that your plant is receiving. These are common problems and can be resolved quickly. It might be a water issue, so be sure to follow the proper watering regime during the growing season. Also, the current pot might be too small for your plant and cannot receive as much water that it needs. So, it might be the time to repot it or divide the roots. It could also be a matter of room humidity so be sure to keep it between 40-50%. Misting often with air sprayer is also a good idea.

My boston fern is showing burned tips, what do I do?

more more
This usually happens if you use too much of fertilizer. This can happen to the root system as well. This is easy to resolve- just flush your soil with water (do not use a strong water stream, as to not damage the roots) and try reducing fertilizer, especially if growing it on a rich substrate. Also, do not add fertilizer during winter dormancy period.

How to Water Boston fern?

Cultivation:WaterDetail
The soil of boston fern should be kept moist and aerated throughout the growing season. However, do not overwater as the root system is very sensitive to soggy substrate and plant’s leaves might wilt. Rainwater is perfect, but tap water is also acceptable as long as it is kept for a while on a room temperature. During the warm weather, the plant can be watered several times a week. During the winter, the watering regime should be less frequent. This means that the plant should be watered when the top part of the soil has dried out, in order to imitate natural conditions for dormancy.
Apart from ample watering, boston fern requires ample air humidity. It will grow in less humid location, but will likely not develop lush and green leaves. This means that this is the perfect plant for your bathroom and/or our kitchen. On occasion, water spray to increase the humidity levels.

How to Fertilize Boston fern?

Cultivation:FertilizerDetail
Boston fern will appreciate additional nourishment, however, fertilizing will depend from the age and soil type of your plant. Generally, recently potted plants do not really require any additional nourishment. As the plant grows and gets repotted, additional nourishment should be added. Using a general all-purpose fertiliser (liquid or slow-release pellets) which contains roughly equal proportions of the three main elements (N%-P2O5%-K2O%) with 20-10-20 would do the trick. If your boston fern is grown on a humus or turf-based rich substrates, you should fertilize it once a month; on sandy-loamy substrates, apply fertilizer twice a month.

Fertilizer

Often found growing in tropical shade gardens Boston fern is an attractive addition to the area. It serves as an anchor plant and adds texture. Best of all, it requires little care beyond watering and occasional feeding. So, when do you fertilize Boston fern, and is there a best time? Like most garden and contain plants, Boston fern does have a few requirements to keep it healthy and thriving.
Why you need to fertilize Boston fern is pretty simple. Your plant needs the extra nutrients to produce healthy new growth. The additional nutrients also support the health of old growth and can help your plant fight off diseases and pests.
Where Boston fern is growing determines its feeding schedule. It is not a particularly hungry plant but does require some additional nutrients. Outdoor plants require fertilizing once in the spring, while indoor specimens need a monthly feeding starting in the spring and continuing through the summer.
You have a few options when choosing a fertilizer for Boston fern. It also depends on if the plant is growing indoors or in the garden. Outdoor plants will thrive with a layer of mulch or compost. For indoor plants,an ideal fertilizer will have an N-P-K ratio of 3-1-2. However, a general-purpose fertilizer that has an even blend of nutrients can work well in some cases. Still, even when using a balanced fertilizer, the ratio number representing the volume of each nutrient should be at 3 or lower.
Fertilizing Boston fern isn’t difficult, but it will depend on where the plant is growing. Outdoor garden plants do best when a layer of mulch or compost is added to the soil. Make sure the organic material is around the base of the plant. Indoor plants typically thrive with a diluted liquid fertilizer applied before watering, monthly in the spring and summer.
You want to remember Boston fern is a slow feeder. It does not require a lot of extra nutrients, especially nitrogen. While fertilizer does help support health growth, too much can burn the plant’s sensitive root system.
Do not fertilize after the early autumn, which can cause too much growth just before winter. Also, Boston fern should not be fertilized during hot and dry times of year, since dry soil does not deliver fertilizer as effectively as moist soil. Fertilizing at this time can also stimulate growth which in turn needs more water that may not be available. It is best to keep fertilizer for earlier in the season when temperatures are cooler. Finally, remember that Boston fern can absorb fertilizer that has been applied to nearby plants or lawns, so be cautious about inadvertently giving ferns a double-dose of fertilizer.

What Are the Sunlight Requirements for Boston fern?

Cultivation:SunlightDetail
Boston fern grows on forest floor and does not tolerate well bright sunlight. It should thus be placed in a bright position if kept as a house plant, without being exposed to direct sunlight except during the winter months. A perfect position is to be placed on a window facing the rising or setting sun. In this way, the plant will be protected from the midday sun, which can be the most damaging.

How to Prune Boston fern?

Cultivation:PruningDetail
If your boston fern starts to exhibit old, discoloured or sick leaves, it will require some pruning in order to maintain its best and healthiest form. This can often happen as new growth shades older leaves. Also, damaged leaves should be removed as to keep the aesthetics and the overall health of the plant. Ideal time for trimming old leaves is during replanting, but if needed, it can be pruned in spring or summer. Always use clean, sharp tools. When removing the leaves, do not cut the top of the plant and instead prune the side leaves. Remove them as close to the base as possible as to ensure the space for the new growth. Wilted leaves should be trimmed down roughly 5 cm toward the base. Wear garden gloves and to disinfect your pruning tools between the cuts to minimize the risks of contamination.

What is the Ideal Temperature Range for Boston fern?

Cultivation:WaterAndHardinessDetail
Boston fern is native to warmer regions and likes increased temperatures. It can grow on temperature between 16 to 27 ℃, but will be able to survive for a shorter time periods in colder temperatures (down to 10 ℃). However, it will grow the happiest at room temperature (21 ℃). It also requires a constant regime of slightly elevated humidity of both air and soil.

What Soil is Best for Boston fern?

Cultivation:SoilDetail
Boston fern requires a rich organic mixture soil that is well aerated and drained. This plant requires a lot of moisture, but is poorly tolerant to stand in water. You should make sure that the drainage is adequate as soggy soil might cause root rots to your boston fern. Soil should be slightly acidic (pH 5.0-5.5), medium rich with nutrients and rich in humus. A loamy mix of normal potting soil, compost and one third of turf should do the trick.
Cultivation:PropagationDetail

How to Propagate Boston fern?

Cultivation:PropagationDetail
As boston fern does not produce flowers and seed, they can be propagated via spores and rhizome division. However, spores of cultivated breeds are usually sterile and will not sprout. Mature ferns will have more than one rosette-shaped vegetation point called funnels on the rhizome. A good time to propagate it is during the repotting, as not to needlessly extract and stress the plant several times. Just cut one of the funnels with a very sharp knife and plant both plant parts in separate containers. As always, remember to wear gloves and disinfect your tools.

Propagation

Boston fern provides a unique decoration for your garden and this plant is relatively easy to propagate. If you want to propagate more Boston fern, our article will show you the method. You can propagate this plant by division. You can divide your plants either during the spring or the fall. If you divide during the spring, you should do so earlier in the season to give your plant a better chance of adapting to the division before the summer heat arrives. The same is true during fall, as you should divide early enough to give your plant time to recover before the cold winter temperatures arrive. Dividing a plant is not difficult to do, but it is much easier to perform when you have the right tools available to you. Here is a basic list of what you’ll need:
  1. A digging shovel or a knife (preferable one with a pointed blade rather than a flat one)
  2. Diluted bleach solution or isopropyl alcohol to clean tools
  3. A water source (garden hose, watering can, etc.)
Steps: Step 1: Use your shovel to dig around the entire parent plant and lift it out of the ground. Step 2: Loosen and separate the main roots to have a better idea of where to divide the plant. Step 3:You can just pull the above-ground part of the plant to separate Boston fern if it is easier. If the root system is tightly wound, use your shovel or knife to slice down through the root ball to divide the plant into two parts. Repeat if you have a large plant you wish to divide more than once. Diluted bleach solution or isopropyl alcohol is required to sterilize the tools before use. Step 4: Wait for the wounds caused by plant division to dry, re-plant your parent plant in its original place. Transplant the divided portion to a new growing location.

How to Plant Boston fern?

Cultivation:PlantingDetail
Location is important so avoid direct sunlight. The plant will tolerate direct sun only in the mornings and evenings and during the winter time. Air humidity is required and it doesn’t tolerate drought. Also, to prevent excessive drying, the plant should not be positioned on a place of frequent drought.
When the plant’s root system overgrows the size of its current container, it should be repotted. You will detect this by gently pulling the root bale out of the pot. If it is overcrowded or whitish root fibrils (tiny light, root-like hairs) are visible on the outer edge of the bale, the plant should be repotted. The repotting should be done in spring. Carefully remove as much of the previous substrate from the root system, fill the new container up to half with the new soil and place the plant in the pot. Afterwards, fill up the empty space around the plant with the rest of the soil. Water generously at the end.

Underwatering
Underwatering Underwatering Underwatering
Leaves may wilt for a variety of reasons.
Solutions: The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with. Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock. In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.

Underwatering
Leaves may wilt for a variety of reasons.
Overview
Overview
Underwatering plants is one of the quickest ways to kill them. This is something that most gardeners are well aware of. Unfortunately, knowing exactly how much water a plant needs can be tricky, especially considering that underwatering and overwatering present similar symptoms in plants.
Therefore, it’s important to be vigilant and attentive to each plants’ individual needs.
Symptom Analysis
Symptom Analysis
As mentioned earlier, overwatering and underwatering present similar symptoms in plants. These symptoms include poor growth, wilted leaves, defoliation, and brown leaf tips or margins. Ultimately, both underwatering and overwatering can lead to the death of a plant.
The easiest way to determine whether a plant has too much water or too little is to look at the leaves. If underwatering is the culprit, the leaves will look brown and crunchy, while if it’s overwatering, they will appear yellow or a pale green in color.
When this issue first begins, there may be no noticeable symptoms at all, particularly in hardy or drought-tolerant plants. However, they will begin to wilt once they start suffering from a lack of water. The edges of the plant’s leaves will become brown or curled. Soil pulling away from the edges of the planter is a telltale sign, or a crispy, brittle stem.
Prolonged underwatering can cause a plant’s growth to become stunted. The leaves might drop and the plant can be more susceptible to pest infestations, too.
Disease Cause
Disease Cause
Underwatering is caused by, quite simply, not watering plants often or deeply enough. There is a heightened risk of underwatering if any of these situations apply:
  • Extreme heat and dry weather (when growing outdoors)
  • Grow lights or indoor lighting that is too bright or intense for the type of plant
  • Using fast-draining growing media such as sand
Solutions
Solutions
The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with.
Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock.
In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.
Prevention
Prevention
Always check the soil before watering. If the top inch of soil feels moist, though not wet, the watering is perfect. If it’s dry, water it immediately. If it feels soggy, you avoid watering until it dries out a bit more.
Also, make sure the lighting is sufficient for the species. Plants grow faster and need more water when there is intense light or lots of heat. Being aware of these conditions and modifying them, if possible, is a good way to prevent underwatering. Many container plants are potted in soil mixtures mean to be well-draining. Adding materials that retain moisture, like compost or peat moss, can also prevent these symptoms.
Other tips to prevent underwatering include:
  • Choose pots with adequately-sized drainage holes
  • Avoid warm temperatures
  • Use large pots with additional soil (these take longer to dry out)
  • Avoid terracotta pots, which lose water quickly

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.
Solutions
Solutions
If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
Prevention
Prevention
Unfortunately, there is no way to prevent plants from dying of “old age.” To help prolong their life, and put off symptoms of aged yellow and dry for as long as possible, take care of them by giving them enough water, fertilizing them appropriately, and making sure they get enough sunlight.

Name story

Boston swordfern
When you observed the leaves carefully, you will notice that the leaves are gradually getting narrow from the aerial root to the top, like a sword. So, it is called swordfern. As for Boston, it was shipped from Philadelphia in 1984 to Boston and that was when the plant started to transform. The straightened leaves become elegant, and because of the transportation, it is called Boston swordfern.

Common Problems

feedback

The leaves of my boston fern is showing signs of discoloration, why is this happening?

more more
This is usually happening when there is wrong with the care that your plant is receiving. These are common problems and can be resolved quickly. It might be a water issue, so be sure to follow the proper watering regime during the growing season. Also, the current pot might be too small for your plant and cannot receive as much water that it needs. So, it might be the time to repot it or divide the roots. It could also be a matter of room humidity so be sure to keep it between 40-50%. Misting often with air sprayer is also a good idea.

My boston fern is showing burned tips, what do I do?

more more
This usually happens if you use too much of fertilizer. This can happen to the root system as well. This is easy to resolve- just flush your soil with water (do not use a strong water stream, as to not damage the roots) and try reducing fertilizer, especially if growing it on a rich substrate. Also, do not add fertilizer during winter dormancy period.

Boston Fern Watering Instructions
Boston fern finds its roots in the sub-tropical and tropical rainforests, with a predilection for warm, humid climates. Hailing from regions in Africa, Central and South America, it evolved in spots with frequent rain showers, average high humidity, and shaded light. Translating this into watering protocol, boston fern craves modest, consistent moisture without being waterlogged. Droplet application, reflecting the plant's native humidity, proves optimal, interspersed with periods of slight drying to mirror natural rain cycles.
When Should I Water My Boston Fern?
Importance
Timely watering is crucial for maintaining the overall health and growth of boston fern. Carefully monitoring the plant can provide indicators of when it's time to water, thereby ensuring it receives just the right amount of water at the right time.
Soil Dryness
This is one of the significant indicators. If the top 1-2 inches of the soil appears dry, it's a clear sign that boston fern needs watering. Touch the soil to ascertain its moisture levels.
Leaf Drooping
Keep an eye on the foliage. If the fronds (leaves) of boston fern start drooping or losing their usual firmness, it indicates that the plant needs water.
Leaf Browning
Though boston fern is usually resistant to browning, if you notice the edges of its fronds turning brown, it's possibly due to lack of water. However, ensure to check other factors like temperature and sunlight exposure as well.
Leaf Curling
Often, when boston fern is water-deprived, the fronds start to curl up. It's a sign that your boston fern needs watering.
Risks
Watering boston fern too early when the soil is still moist can lead to waterlogging and root rot, a deterioration condition often lethal to the plant. On the other hand, watering too late when the plant has been water-starved for an extended period could cause irreversible damage such as leaf browning or curling.
How Should I Water My Boston Fern?
Plant Sensitivity and Watering Requirements
Boston fern is highly sensitive to its watering habits. It predominantly requires a high humidity environment to thrive and can be delicate when it comes to its hydration regimen. Key to its care is ensuring the soil stays damp and it is not subjected to waterlogged conditions. Overwatering or underwatering can impair its growth and overall health.
Watering Technique #1 - Bottom Watering
Bottom watering ensures the roots of boston fern get adequate moisture without causing waterlogged conditions or promoting fungal growth. To perform this method, place the boston fern pot in a shallow tray of water and allow it to soak up the water for about 30-45 minutes. Once damp, remove it from the tray and allow excess water to drain out.
Watering Technique #2 - Misting
Misting is a great method to increase humidity for boston fern. Regular misting with soft, lukewarm water can maintain the required moisture level and mimic a humid environment. A plant mister can be used to regularly mist the entire plant focusing on the fronds, but avoid over-misting which can drown the plant.
Watering Equipment - Moisture Meter and Watering Can
A moisture meter can be an invaluable tool for boston fern care. This tool measures the moisture content in the soil, alerting caregivers when it is time to water. A watering can with a long, narrow spout or a squeeze-bottle is ideal for this plant, allowing for directed watering at the base without wetting the foliage.
Areas To Focus On During Watering
During watering, focus on the soil, ensuring that it becomes damp but not water-clogged. Overwatering can lead to root rot challenges. Also, avoid wetting the center of the fern where the new fronds form. Too much moisture here can cause fungal growth.
Areas To Avoid During Watering
While boston fern enjoys a humid environment, direct, constant moisture on the fronds or foliage can lead to brown, dead fronds and fungal issues. Thus, while misting, be gentle and avoid waterlogged conditions.
How Much Water Does Boston Fern Really Need?
Introduction
Boston fern's natural habitat is the understory of warm, humid tropical forests. These conditions indicate that it prefers a consistently moist, but not waterlogged, soil environment.
Water Quantity
The optimal water quantity for boston fern hinges not just on the plant size, but also on root depth and pot size. Container size plays a significant role here - a shallow, small pot may necessitate more frequent waterings than a deeper, larger one. As a general guideline, for a standard 5-6 inch potted boston fern, watering until the top one inch soil becomes moist, and making sure any excess water can drain out, should suffice.
Signs and Indicators
The boston fern's fronds can often indicate its watering conditions. Healthily hydrated boston ferns should boast bright green, vibrant fronds. If the fronds begin to yellow, wilt or dry out, it can be a sign of under-watering. Alternatively, if the frond tips start to brown and the plant base turns soft and black, it may be a sign of overwatering or poor drainage.
Overwatering and Underwatering Risks
The dangers of overwatering boston fern can lead to root rot, preventing oxygen from reaching the roots and potentially killing the plant. Underwatering, on the other hand, deprives the plant of necessary moisture, causing it to wilt and potentially die in extreme cases.
