Reasons for Fern Turning Brown
Ferns are known for their lush green foliage, which adds a touch of elegance and freshness to any indoor or outdoor space. However, it can be disheartening to see your ferns turning brown. Several factors can contribute to this browning phenomenon, and it’s essential to understand them to ensure the health and vitality of your ferns.
Lack of Water
One of the primary reasons ferns turn brown is a lack of water. Ferns thrive in moist environments, and when they don’t receive enough water, their fronds start to dry out and turn brown. This is especially true during the hot summer months or if the ferns are placed in areas with low humidity. To prevent this, make sure you water your ferns regularly and keep the soil consistently moist but not waterlogged.
Overwatering
On the flip side, overwatering can also cause ferns to turn brown. When the roots of the ferns are constantly saturated with water, they can’t absorb oxygen properly, leading to root rot. This root rot prevents the ferns from taking up essential nutrients, causing their fronds to turn brown. It’s crucial to strike a balance and ensure that you water your ferns adequately without drowning them.
Insufficient Light
Ferns thrive in indirect or filtered light conditions. If your ferns are not receiving enough light, their fronds may start to turn brown. This is because the lack of light hinders the ferns’ ability to perform photosynthesis effectively, leading to browning and decreased vitality. Ensure that you place your ferns in a location where they can receive sufficient light, but avoid exposing them to direct sunlight, as this can cause sunburn.
Excessive Direct Sunlight
While ferns require light for their growth, excessive direct sunlight can be detrimental to their health. Ferns are shade-loving plants and are adapted to thrive in the understory of forests. When exposed to intense sunlight for prolonged periods, their delicate fronds can get scorched and turn brown. If you notice your ferns receiving direct sunlight, consider moving them to a more shaded area or providing them with some form of protection, such as sheer curtains or a shade cloth.
Low Humidity
Ferns are native to regions with high humidity levels, and they require a moist environment to thrive. When the air around them is too dry, their fronds may start to turn brown. This is because low humidity causes the ferns to lose water faster through transpiration, leading to dehydration and browning. Increase the humidity around your ferns by misting them regularly, placing a tray of water nearby, or using a humidifier.
Temperature Extremes
Ferns prefer moderate temperatures and can suffer when exposed to extreme cold or heat. When the temperature drops too low, ferns may experience frost damage, causing their fronds to turn brown. Similarly, excessive heat can lead to dehydration and browning. It’s important to provide your ferns with a temperature-controlled environment, avoiding drafts and extreme temperature fluctuations.
Nutrient Deficiency
Like any other plant, ferns require a balanced supply of nutrients to thrive. A lack of essential nutrients, such as nitrogen, phosphorus, and potassium, can result in the browning of fern fronds. It’s important to fertilize your ferns regularly with a balanced fertilizer specifically formulated for ferns. This will ensure that they receive the necessary nutrients to maintain their vibrant green color.
Soil pH Imbalance
Ferns prefer slightly acidic to neutral soil conditions. If the pH of the soil becomes too acidic or alkaline, it can affect the ferns’ ability to absorb nutrients properly, leading to browning. Test the pH of your ferns’ soil regularly using a pH testing kit and adjust it accordingly. Adding organic matter or using soil amendments can help balance the pH and create an optimal environment for your ferns to thrive.
Pest Infestation
Pests can wreak havoc on ferns, causing them to turn brown. Common pests that affect ferns include aphids, mealybugs, scale insects, and spider mites. These pests feed on the ferns’ foliage, sucking out vital nutrients and leaving behind a trail of damage. Regularly inspect your ferns for signs of pest infestation, such as small insects, webbing, or distorted fronds. If you notice any pests, treat them promptly using organic insecticides or by manually removing them.
Disease or Fungal Infection
Ferns are susceptible to various diseases and fungal infections, which can cause their fronds to turn brown. Root rot, leaf spot, and powdery mildew are common issues that can affect ferns. These diseases are often caused by overwatering, poor air circulation, or high humidity. To prevent and treat these issues, ensure proper watering practices, provide adequate air circulation, and promptly remove any infected fronds. Fungicides can also be used to control fungal infections if necessary.
Remedies for Brown Fern

One of the most common reasons why ferns turn brown is due to improper watering. It is important to find the right balance between underwatering and overwatering to ensure the health and vitality of your fern. Adjusting the watering schedule can help prevent browning and promote lush green foliage.
To determine the ideal watering schedule for your fern, consider factors such as the plant’s size, the type of pot it is in, and the humidity levels in your environment. Generally, ferns prefer moist but not waterlogged soil. A good rule of thumb is to water your fern when the top inch of soil feels slightly dry to the touch.
Checking Soil Moisture
Checking the moisture level of the soil is crucial in maintaining a healthy fern. Brown ferns often indicate that the soil is either too dry or too wet. To check the moisture level, insert your finger about an inch into the soil. If it feels dry, it’s time to water the fern. On the other hand, if it feels overly damp, hold off on watering until the soil has a chance to dry out a bit.
Another helpful tool for monitoring soil moisture is a moisture meter. These inexpensive devices can provide a more accurate reading of the soil’s moisture content. Simply insert the probe into the soil and check the reading. This can help you determine if the fern needs watering or if the soil is already too damp.
Providing Adequate Light
Insufficient light can also contribute to the browning of ferns. These delicate plants thrive in moderate to bright indirect light. If your fern is not receiving enough light, it may struggle to produce chlorophyll, leading to brown foliage.
To remedy this, find a suitable location for your fern where it can receive the right amount of light. Place it near a window with filtered sunlight or use artificial lighting, such as fluorescent grow lights, to supplement natural light. Be mindful of direct sunlight, as excessive exposure can scorch the fern’s leaves and cause further browning.
