Common Reasons for Bonsai Tree Browning
If you have noticed that your once vibrant bonsai tree is turning brown, there are several reasons why this could be happening. In this section, we will explore some of the most common reasons for bonsai tree browning and what you can do to fix the problem.
Improper Watering
One of the most common reasons for bonsai tree browning is improper watering. Overwatering or underwatering your bonsai can lead to stress and cause the leaves to turn brown. It is essential to maintain a proper watering schedule based on the species of your bonsai tree and the size of the pot it is in.
To determine if your bonsai needs watering, you can insert a toothpick or chopstick into the soil. If it comes out dry, it’s time to water your bonsai. On the other hand, if it comes out wet or damp, wait for a day or two before watering again.
Inadequate Light
Another common reason for bonsai tree browning is inadequate light. Insufficient light can result in the leaves turning brown due to the lack of necessary energy for photosynthesis. Determine the light requirements of your bonsai species and place it in a location with the appropriate amount of sunlight or artificial light.
If you notice that your bonsai tree is not getting enough light, you can consider using a grow light to supplement the natural light. A grow light can provide the necessary spectrum of light that your bonsai needs to thrive.

Temperature and humidity are two factors that significantly impact the health of your bonsai tree. Bonsai trees thrive in specific temperature ranges depending on their species. Ensuring a stable and appropriate temperature is essential for their well-being. Temperature fluctuations or exposure to extreme heat or cold can cause the leaves to turn brown and eventually fall off.
In general, bonsai trees prefer a temperature range between 60°F to 75°F (15°C to 23°C) during the day and 50°F to 60°F (10°C to 15°C) at night. However, some species may require slightly different temperature ranges. For example, tropical bonsai trees like Ficus and Schefflera prefer temperatures between 70°F to 85°F (21°C to 29°C).
Humidity is another crucial factor that affects the health of your bonsai tree. Bonsai trees thrive in a humid environment, and low humidity levels can cause the leaves to turn brown and fall off. In general, bonsai trees prefer a humidity level of around 50%. However, some species may require higher or lower humidity levels. For example, tropical bonsai trees like Ficus and Schefflera prefer higher humidity levels, while juniper bonsai trees prefer lower humidity levels.
To maintain the appropriate temperature and humidity levels, you may need to use a humidifier or a dehumidifier, depending on the needs of your bonsai tree. You can also use a thermometer and a hygrometer to monitor the temperature and humidity levels in the area where your bonsai tree is located.

The soil and fertilizer you use for your bonsai tree can have a big impact on its health. Here are some common soil and fertilizer issues that can cause your bonsai tree to turn brown:
1. Poor Soil Drainage
If your bonsai tree is planted in soil that doesn’t drain well, the roots can become waterlogged and start to rot. This can cause the leaves to turn brown and fall off. To prevent this, make sure your soil has good drainage. You can achieve this by adding perlite or sand to your soil mix.
2. Over-Fertilization
Over-fertilizing your bonsai tree can cause the roots to burn, which can lead to brown leaves. Make sure you are using the right type of fertilizer and following the recommended dosage. It’s also a good idea to fertilize your bonsai tree less frequently during the winter months when it’s not actively growing.
3. Under-Fertilization
On the other hand, if you’re not fertilizing your bonsai tree enough, it may not be getting the nutrients it needs to stay healthy. This can cause the leaves to turn yellow and then brown. Make sure you’re using a high-quality fertilizer and following the recommended dosage.
4. Soil Compaction
If the soil around your bonsai tree becomes too compacted, it can prevent water and nutrients from reaching the roots. This can cause the leaves to turn brown and fall off. To prevent soil compaction, make sure you’re using a well-draining soil mix and avoid packing the soil too tightly around the roots.
By addressing these soil and fertilizer issues, you can help prevent your bonsai tree from turning brown and keep it healthy and thriving.
