What is the best way to water my Old world forked fern?
When watering the Old world forked fern, you should aim to use filtered water that is at room temperature. Filtered water is better for this plant, as tap water can contain particles that are harmful to its health. The reason that the water should be at room temperature or slightly warmer is that the Old world forked fern comes from a warm environment, and cold water can be somewhat of a shock to its system. Also, you should avoid overhead watering for this plant, as it can cause foliage complications. Instead, simply apply your filtered room temperature water to the soil until the soil is entirely soaked. Soaking the soil can be very beneficial for this plant as it moistens the roots and helps them continue to spread through the soil and collect the nutrients they need.

What should I do if I water my Old world forked fern too much or too little?
Both overwatering and underwatering will be detrimental to the health of your Old world forked fern, but overwatering is a far more common issue. When this species receives too much water, its stems and leaves may begin to wilt and turn from green to yellow. Overwatering over a prolonged period may also lead to diseases such as root rot, mold, and mildew, all of which can kill your plant. Underwatering is far less common for the Old world forked fern, as this plant has decent drought tolerance. However, underwatering remains a possibility, and when it occurs, you can expect to find that the leaves of your Old world forked fern have become brittle and brown. It is crucial that you notice the signs of overwatering as soon as possible when caring for your Old world forked fern. Some of the diseases that arise from overwatering, such as root rot, may not be correctable if you wait too long. If you see early signs of overwatering, you should reduce your watering schedule immediately. You may also want to assess the quality of soil in which your Old world forked fern grows. If you find that the soil drains very poorly, you should replace it immediately with a loose, well-draining potting mix. On the other hand, if you find signs that your Old world forked fern is receiving too little water, all you need to do is water more regularly until those signs have subsided.

How often should I water my Old world forked fern?
If your plant is in a pot. The most precise way to decide whether your Old world forked fern needs water is to plunge your finger into the soil. If you notice that the first two to three inches of soil have become dry, it is time to add some water. If you grow your Old world forked fern outdoors in the ground, you can use a similar method to test the soil. Again, when you find that the first few inches of soil have dried out, it is time to add water. During the spring and early fall, this method will often lead you to water this plant about once every week. When extremely hot weather arrives, you may need to increase your watering frequency to about twice or more per week. With that said, mature, well-established the Old world forked fern can show an admirable ability to withstand drought.

How much water does my Old world forked fern need?
When it comes time to water your Old world forked fern, you should not be shy about how much water you give. With the first two to three inches of soil dry, this plant will appreciate a long and thorough watering. Supply enough water to soak the soil entirely. The amount of water you add should be enough to cause excess water to flow through the drainage holes at the bottom of your pot. If you don’t see excess water draining from the pot, you have likely underwatered your plant. But do not let the water accumulate inside the soil, which will be very dangerous to the plant as well. Alternatively, a lack of water draining through the pot could indicate poorly draining soils, which is detrimental to the health of this plant and should be avoided. If the plant is outside, 1 inch of rain per week will be sufficient.

How should I water my Old world forked fern at different growth stages?
The water needs of the Old world forked fern can change depending on growth stages as well. For example, when your Old world forked fern is in the first few years of its life, or if you have just transplanted it to a new growing location, you will need to give more water than usual. During both of those stages, your Old world forked fern will put a lot of energy towards sprouting new roots that will then support future growth. For those roots to perform their best, they need a bit more moisture than they would at a more mature phase. After a few seasons, your Old world forked fern will need much less water. Another growth stage in which this plant may need more water is during the bloom period. Flower development can make use of a significant amount of moisture, which is why you might need to give your Old world forked fern more water at this time.
Read More more
How should I water my Old world forked fern through the seasons?
The Old world forked fern will have its highest water needs during the hottest months of the year. During the height of summer, you may need to give this plant water more than once per week, depending on how fast the soil dries out. The opposite is true during the winter. In winter, your plant will enter a dormant phase, in which it will need far less water than usual. In fact, you may not need to water this plant at all during the winter months. However, if you do water during winter, you should not do so more than about once per month. Watering too much at this time will make it more likely that your Old world forked fern will contract a disease.

What's the difference between watering my Old world forked fern indoors and outdoors?
It is most common to grow the Old world forked fern indoors for any gardener that does not live in temperate and tropical regions. Those gardeners should consider the fact that soil in a container can dry out a bit faster than ground soil. Also, the presence of drying elements such as air conditioning units can cause your Old world forked fern to need water on a more frequent basis as well. if you planted it outside. When that is the case, it’s likely you won’t need to water your Old world forked fern very much at all. If you receive rainfall on a regular basis, that may be enough to keep your plant alive. Alternatively, those who grow this plant inside will need to water it more often, as allowing rainwater to soak the soil will not be an option.

Common issues for Old world forked fern based on 10 million real cases
Leaf scorch
Leaf scorch Leaf scorch
Leaf scorch
Leaf blight causes leaves to dry out and turn brown starting at their tips.
Solutions: The solution to leaf scorch will depend on the cause, however, in general all cultural care methods that improve plant health and root functionality will reduce symptoms. Mulching the root zone (preferably with wood chip mulch) helps retain moisture, reduce evaporation, and promotes a healthy, functional root environment that is critical for water movement to the leaves. Check the root collar for girdling or circling roots that strangle the trunk and limit water and nutrient movement. Protect trees from severe root damage of nearby construction and excavation. If fertilizer burn is to blame, irrigate the soil deeply to flush out excess fertilizer salts. However, keep in mind that fertilizer runoff is an environmental pollutant. Avoiding excess fertilization in the first place is the best approach. If soil testing has revealed a potassium deficiency, apply a potassium fertilizer and water well. Even if you have enough potassium in the soil, plants will not be able to take it up if the soil is consistently too dry. Severely affected twigs may be removed using a pair of sharp and sanitized pruning shears, as weakened branches are susceptible to secondary infections. If your plant has bacterial leaf scorch, there is no cure. Antibiotic injections applied by a professional can reduce symptoms for a season, however, the above cultural management methods are the best options to reduce symptoms and prolong life. An infected plant will likely die within ten years.
Fruit rot

Leaf scorch
plant poor
Leaf scorch
Leaf blight causes leaves to dry out and turn brown starting at their tips.
Overview
Overview
Leaf scorch refers to two general conditions: physiological leaf scorch and bacterial leaf scorch. It causes leaves to discolor starting along the margins, and eventually die.
Leaf scorch development is most common in the hot, dry season, becoming most noticeable in late summer. However, it can occur at other times of the year. It most often affects young trees and shrubs, but it can also affect flowers, vegetables, and other plants.
Leaf scorch can get progressively worse over multiple seasons. If the root causes are not addressed, leaf scorch can lead to plant death.
While you cannot reverse the damage caused by physiological leaf scorch, you can prevent further damage. With proper management, plants will fully recover. However, there is no cure for bacterial leaf scorch, which is a systemic infection.
Symptom Analysis
Symptom Analysis
  • Yellow, brown, or blackened leaves starting with the leaf margins
  • Dying twig tips on trees and shrubs as leaves die and fall
  • Often there is a bright yellow border line between the dead and living leaf tissue
Disease Cause
Disease Cause
There are numerous contributing causes of leaf scorch.
Bacterial leaf scorch is caused by the bacterium Xylella fastidiosa. The bacteria block the xylem vessels, preventing water movement. Symptoms may vary across species.
Physiological leaf scorch most commonly occurs when a plant cannot take up enough water. Numerous conditions can lead to this issue, particularly an unhealthy root system. Some causes of an unhealthy root system include overly-compacted soil, recent tillage, root compaction and severing due to pavement or other construction, drought, and overly-saturated soils.
Potassium deficiency can contribute to leaf scorch. Since plants need potassium to move water, they cannot properly move water when there is a lack of potassium.
Too much fertilizer can also cause leaf scorch symptoms. The accumulation of salts (including nutrient salts from fertilizers, as well as salt water) accumulate at the leaf margins and may build up to concentrations that burn the tissues.

Fruit rot

Fruit rot
Soft rot in the fruit can have a variety of causes.
Overview
Overview
Fruit rot is quite common, and there are a large number of factors that can lie at the heart of this problem. Symptoms also vary from fruit to fruit and from cause to cause, but in general, one can recognize fruit that is rotten or starting to rot. Many of the most common causes of rotting are related to fungal diseases, which enter the fruit through wounds such as those caused by birds. The disease then spreads outwards from the wound. From there it can spread to neighboring fruit or be carried by the wind to plants further away.
Symptom Analysis
Symptom Analysis
Below are some of the broader symptoms to look out for in cases of fruit rot. If this occurs on just one or two fruit it may just be as the result of a small-scale infection, but if it is widespread then a fungal infection problem is likely.
  1. Small brown spots appear on the fruit.
  2. Brown spots expand, normally in concentric circles and the center starts to go soft and mushy.
  3. Mushiness spreads and grey or brown powdery pustules start to coat the fruit.
  4. Some fruit will drop but others may remain and gradually turn mummified.
Disease Cause
Disease Cause
Fruit rot is often caused by fungal infection. These fungi overwinter on fallen fruit, and then the spores are spread by the wind the following spring. Birds and sap-sucking insects can also act as vectors. Entry to new fruit is made considerably easier if there are wounds of any kind through which the spores can penetrate the skin. The healthier the tree or plant, the better able it is to defend itself from infection.

  • Have your soil tested and apply the proper nutrients. Be sure to not over-apply fertilizers.
  • Make sure your plants’ roots have room to expand. Avoid compacted soil as well and avoid paving areas above the root zone. Do not till or disturb the soil where plant roots are growing.
  • Plant new trees and shrubs in the fall, so that they have the maximum amount of time to become established before the environmental stresses of the next summer.
  • Remove any dead or dying plant tissue that may harbor secondary infections.

Prevention
Prevention
To prevent pests and disease infection:
  1. Pick fruits on time. Remove fruit once ripe to prevent opportunities for pests and fungal infections to take hold.
  2. Rake and clean debris. Remove and bury surrounding plant material that may host diseases.
  3. Prune branches and thin fruit. Remove ripening fruits so they do not touch one another and prune branches to improve air circulation (reducing the wet conditions in which fungi thrive).
  4. Consider preventative use of fungicide prior to fruit forming.
To prevent nutrient deficiency that weakens the plant:
  1. Add mulch. Adding a layer of mulch on top of the soil early in the season will keep moisture even.
  2. Use organic fertilizer. Plants given ammonia-based fertilizer cannot uptake calcium efficiently. Use compost, fish emulsion, liquid kelp or other organic fertilizer.

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.

(Symptom details and solutions)
Small leaves
New leaves may grow smaller in size compared to the previous ones once they have matured.
Leggy or sparse growth
The spaces between leaves or stems of your Old world forked fern may become longer, resulting in a thin and stretched-out appearance. This can make the plant look sparse and weak, and it may easily break or lean due to its own weight.
Faster leaf drop
When plants are exposed to low light conditions, they tend to shed older leaves early to conserve resources. Within a limited time, these resources can be utilized to grow new leaves until the plant's energy reserves are depleted.
Slower or no new growth
Old world forked 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.
Lighter-colored new leaves
Insufficient sunlight can cause leaves to develop irregular color patterns or appear pale. This indicates a lack of chlorophyll and essential nutrients.
Solutions
1. To ensure optimal growth, gradually move plants to a sunnier location each week, until they receive at least 6 hours of direct sunlight daily. Use a south-facing window and keep curtains open during the day for maximum sunlight exposure and nutrient accumulation.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
Old world forked fern thrives in full sun exposure and can tolerate intense sunlight. With their remarkable resilience, symptoms of sunburn may not be easily visible, as they rarely suffer from it.

(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.
