Ficus trees are a popular indoor plant species known for their large, lush leaves and dramatic appearance. However, sometimes these trees may experience issues with their leaves turning brown, which can be a sign of stress or damage. In this article, we’ll explore the common reasons why ficus tree leaves may turn brown, including environmental factors like inadequate watering, exposure to drafts or extreme temperatures, or pest infestations.

Causes of Leaf Browning


One common cause of ficus leaves turning brown is under-watering. When the soil mix in the pot is completely dry, the plant may feel thirsty and experience leaf browning. To fix this issue, fill a water tub with distilled lukewarm water and place the pot in it, ensuring the soil gets completely soaked. From then on, water the plant every few days as the surface of the pot dries out. Make sure the roots have enough space for proper hydration (source).


Over-watering is another leading cause of brown leaves on ficus plants(source). Excessive water can lead to root rot and deprive the plant of oxygen. To address over-watering, allow the soil to dry out between waterings and ensure proper drainage for your ficus tree.

Lack of Humidity

Ficus plants can also experience brown leaves due to insufficient humidity(source). Adequate humidity is essential for ficus trees to thrive, so it’s crucial to maintain an optimal level of moisture in the environment. To increase humidity, regularly mist the leaves, place a water-filled tray near the plant, or use a humidifier.

Poor Soil Drainage

Poor soil drainage can contribute to the problem of browning leaves in ficus plants. Inadequate drainage results in waterlogged soil, which can cause root rot and other issues(source). To improve soil drainage, repot your ficus tree in fresh, well-draining soil and use a pot with drainage holes.

Disease or Pest Infestation

Diseases and pest infestations, such as insect infections, can lead to brown leaves on ficus plants(source). To protect your ficus tree from pests and diseases, regularly inspect the leaves and stems for any signs of infestation or infection. If you notice any issues, use appropriate treatments and preventative measures to maintain your plant’s health.

How to Identify the Problem

When determining the cause of brown leaves on a ficus tree, it’s important to examine a few key factors, such as the pattern of the affected leaves, the tree’s roots, and soil moisture levels. These assessments can guide your approach to improving the health of your ficus tree and preventing future issues.

Assessing Leaf Patterns

First, take note of the changes in the leaves. Look for patterns where the browning is occurring, such as on the tips, margins, or evenly distributed across the entire leaf. Brown leaf tips can be an indication of insufficient water uptake, while leaf margins turning brown may relate to a fungal disease like anthracnose.

Also, examine the ficus for rusty-looking spots or an oozing substance on stems and leaves. These signs can indicate a more serious fungal issue that requires immediate attention and treatment.

Inspecting Roots

The health of your ficus tree’s roots plays a crucial role in its overall well-being. Gently remove the tree from its pot and inspect the root system. Healthy roots should be white and firm, while unhealthy roots may appear dark, slimy, or mushy. Root rot can occur due to over-watering or poorly drained soil, leading to problems such as browning leaves.

Checking Soil Moisture

The soil moisture level for your ficus tree is essential in maintaining its health. If the soil is allowed to dry out completely, the leaves may droop, become crispy, turn brown, and eventually fall off(Bloomscape). To prevent this, ensure that the soil remains consistently moist, but not overly damp, as this can also lead to root rot.

To check the soil moisture, insert your finger about an inch into the soil. If it feels dry at that depth, it’s time to water your ficus. If it’s still moist, wait for a couple of days before checking again.

Solutions and Prevention

Proper Watering Regimen

One of the main reasons for brown leaves on a ficus tree could be improper watering. It is essential to establish a well-regulated watering routine. Ensure that the soil is consistently moist but not waterlogged. A good practice would be to soak-water your plant by filling a basin with 3-4 inches of water and placing the pot in it. This ensures that the soil is completely soaked, and excess water can drain out.

Improving Humidity

Another factor causing brown leaves on a ficus tree is incorrect humidity levels. Ficus trees thrive in environments with higher humidity. To maintain adequate humidity, you can mist the leaves regularly, but be careful not to cause fungal issues. Placing a tray with water under the plant or using a humidifier can also help regulate humidity levels around the tree.

Maintaining Soil Health

Healthy soil is crucial for a verdant ficus tree. Optimal soil composition can prevent brown leaves by providing necessary nutrients and drainage. Ensure that you plant your ficus tree in a well-draining soil mix with appropriate nutrients. Periodically adding fertilizer can help support your tree’s health, but be cautious not to over-fertilize, as this can lead to nutrient toxicity and browning leaves.

Disease and Pest Control

Diseases and pests can cause significant damage to your ficus tree, leading to brown leaves. Regular inspections and prompt treatment can prevent the spread of diseases and pest infestations. Applying sulfur sprays or copper-based fungicides can be an effective method in controlling diseases like leaf spot and anthracnose. Keeping your tree’s environment clean, monitoring for pests, and applying appropriate pest control measures will help ensure the health and longevity of your ficus tree.

Additional Care Tips

Lighting Requirements

Ficus trees require appropriate lighting to maintain their health and prevent issues such as browning leaves. Ensure your ficus tree receives bright, indirect sunlight, as direct sunlight can cause the leaves to burn and turn brown. If your tree is indoors, place it near a window with ample natural light, but avoid exposure to harsh sunlight(source).

Pruning Techniques

Regular pruning promotes healthy growth for your ficus tree. Begin by removing any dead or brown leaves, as they can drain the tree’s energy. Next, trim branches that are overcrowded or cross each other to improve air circulation within the tree. When pruning, always use clean and sharp tools to prevent damage or the spread of disease. Prune during the ficus tree’s active growing season, typically during spring and summer, for optimal results(source).


Proper fertilization is essential for maintaining a healthy ficus tree. Over-fertilizing can cause leaves to turn brown, while under-fertilizing can lead to a lack of nourishment(source). To prevent over-fertilizing, use a slow-release fertilizer and avoid fertilizing during winter months, when the tree’s growth slows down(source).

  • Choose a balanced, slow-release fertilizer such as a 10-10-10 formula.
  • Apply the fertilizer according to the package instructions, typically every 4-8 weeks during the growing season.
  • Ensure even distribution of the fertilizer around the base of the tree and water thoroughly after application(source).
