What should I do if I water my Tuberous sword fern too much or too little?
Overwatered Tuberous sword fern Despite how much it loves water, it is possible to overwater the Tuberous sword 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 Tuberous sword fern is overwatered, since other issues can look similar and it’s difficult to give this plant too much water. Underwatered Tuberous sword 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 Tuberous sword fern properly?
Your Tuberous sword 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.

What should I consider when watering my Tuberous sword fern?
The amount of humidity in the air around your Tuberous sword 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 Tuberous sword fern has very thin and delicate leaves. Small pots can cause issues for Tuberous sword 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 Tuberous sword 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.

Leaf rot
Leaf rot Leaf rot
Leaf rot
Leaf rot is a severe disease that impacts the health and growth of Tuberous sword fern. Characterized by the decay and discoloration of foliage, the disease, if untreated, can lead to plant death. It's caused by fungi and bacteria, and is heavily influenced by environmental conditions.
Brown spot
Brown spot Brown spot
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
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

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
  • Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
  • Placement is often random and scattered as diseases are spread through raindrops.
  • May appear on lower leaves and the interior of the plant where humidity is higher.
  • Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
  • Leaf margins may turn yellow.
  • Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
  • Blotches grow in size until the entire leaf is brown.
  • The leaf falls off the plant.
Severe Symptoms
  • Partial or complete premature defoliation
  • Reduced growth
  • Increased susceptibility to pests and other diseases
Disease Cause
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.

Underwatering
plant poor
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.

Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
  • Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
  • Placement is often random and scattered as diseases are spread through raindrops.
  • May appear on lower leaves and the interior of the plant where humidity is higher.
  • Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
  • Leaf margins may turn yellow.
  • Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
  • Blotches grow in size until the entire leaf is brown.
  • The leaf falls off the plant.
Severe Symptoms
  • Partial or complete premature defoliation
  • Reduced growth
  • Increased susceptibility to pests and other diseases
Disease Cause
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.
Solutions
Solutions
In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary.
Organic options won’t kill the fungus, but will prevent it from spreading.
  1. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear.
  2. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread.
  3. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Prevention
Prevention
Like many other diseases, it is easier to prevent brown spot than cure it, and this is done through cultural practices.
  • Clear fall leaves from the ground before winter to minimize places where fungi and bacteria can overwinter.
  • Maintain good air movement between plants through proper plant spacing.
  • Increase air circulation through the center of plants through pruning.
  • Thoroughly clean all pruning tools after working with diseased plants.
  • Never dispose of disease plant material in a compost pile.
  • Avoid overhead watering to keep moisture off of the foliage.
  • Keep plants healthy by providing adequate sunlight, water, and fertilizer.

Underwatering

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

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.

Indoor plants require adequate lighting for optimal growth. When natural sunlight is insufficient, particularly in winter or in less sunny spaces, artificial lights offer a vital solution, promoting faster, healthier growth.
1. Choose the right type of artificial light: LED lights are a popular choice for indoor plant lighting because they can be customized to provide the specific wavelengths of light that your plants need.
Full sun plants need 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft.
2. Determine the appropriate distance: Place the light source 12-36 inches above the plant to mimic natural sunlight.
3. Determine the duration: Mimic the length of natural daylight hours for your plant species. most plants need 8-12 hours of light per day.
Important Symptoms
Symptoms of Insufficient Light in %s

(Symptom details and solutions)
Slower or no new growth
Tuberous sword fern enters a survival mode when light conditions are poor, which leads to a halt in leaf production. As a result, the plant's growth becomes delayed or stops altogether.
Solutions
1. To optimize plant growth, shift them to increasingly sunnier spots each week until they receive 3-6 hours of direct sunlight daily, enabling gradual adaptation to changing light conditions.2. To provide additional light for your plant, consider using artificial light if it's large or not easily movable. Keep a desk or ceiling lamp on for at least 8 hours daily, or invest in professional plant grow lights for ample light.
Symptoms of Excessive light in %s
Tuberous sword fern prefers shade and is sensitive to direct sunlight. Due to their intolerance to sun exposure, they easily develop symptoms of sunburn, making proper shading essential for their well-being.

(Symptom details and solutions)
Chlorosis
Chlorosis is a condition where the plant's leaves lose their green color and turn yellow. This is due to the breakdown of chlorophyll from excessive sunlight, which negatively affects the plant's ability to photosynthesize.
Sunscald
Sunscald occurs when the plant's leaves or stems are damaged by intense sunlight exposure. It appears as pale, bleached, or necrotic areas on the plant tissue and can reduce the plant's overall health.
Leaf Curling
Leaf curling is a symptom where leaves curl or twist under extreme sunlight conditions. This is a defense mechanism used by the plant to reduce its surface area exposed to sunlight, minimizing water loss and damage.
Wilting
Wilting occurs when a plant loses turgor pressure and its leaves and stems begin to droop. Overexposure to sunlight can cause wilting by increasing the plant's water loss through transpiration, making it difficult for the plant to maintain adequate hydration.
Leaf Scorching
Leaf scorching is a symptom characterized by the appearance of brown, dry, and crispy edges or patches on leaves due to excessive sunlight. This can lead to a reduction in photosynthetic capacity and overall plant health.
Solutions
1. Move your plant to the optimal position where it can receive abundant sunlight but also have some shade. An east-facing window is an ideal choice as the morning sunlight is gentler. This way, your plant can enjoy ample sunlight while reducing the risk of sunburn.2. It is recommended to trim off any completely dehydrated or withered parts of the plant.

Essentials
The tuberous sword fern thrives in warm, humid environments and requires temperatures between 68 to 100℉ (20 to 38℃). It prefers to be kept in a bright area, but out of direct sunlight. During the summer months, it may benefit from a slight increase in humidity levels. During the winter, it is suggested to keep the temperature around 60 to 70℉ (15.5 to 21℃).
Regional wintering strategies
Tuberous sword fern is extremely heat-loving, and any cold temperatures can cause harm to it. In the autumn, it is recommended to bring outdoor-grown Tuberous sword fern indoors and place it near a bright window, but it should be kept at a certain distance from heaters. Maintaining temperatures above {Suitable_growth_temperature_min} during winter is beneficial for plant growth. Any temperatures approaching {Tolerable_growing_temperature_min} are detrimental to the plant.
Important Symptoms
Symptoms of Low Temperature in Tuberous sword fern
Tuberous sword fern prefers warm temperatures and is not tolerant of low temperatures. It thrives best when the temperature is above {Suitable_growth_temperature_min}. During winter, it should be kept above {Tolerable_growing_temperature_min}. When the temperature falls below {Limit_growth_temperature}, the leaves may lighten in color. After frost damage, the color gradually turns brown or black, and symptoms such as wilting and drooping may occur.
Solutions
Trim off the frost-damaged parts. Immediately move indoors to a warm environment for cold protection. Choose a spot near a south-facing window to place the plant, ensuring ample sunlight. Additionally, avoid placing the plant near heaters or air conditioning vents to prevent excessive dryness in the air.
Symptoms of High Temperature in Tuberous sword fern
During summer, Tuberous sword fern should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the color of the leaves becomes lighter, and the plant becomes more susceptible to sunburn.
Solutions
Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun. Water the plant in the morning and evening to keep the soil moist.
