How to Care for a Ficus Bonsai Tree


Indoor Lighting

Proper lighting is crucial for the health and growth of your ficus bonsai tree. Ideally, your tree should be placed near a window where it can receive ample indirect sunlight. Ficus bonsai trees thrive in bright, but not direct, light. If your indoor space lacks natural light, you can supplement it with artificial lighting.

Outdoor Lighting

If you choose to place your ficus bonsai tree outdoors, make sure to find a spot that provides a balance of sunlight and shade. Too much direct sunlight can harm the tree, while insufficient light can prevent healthy growth. It’s essential to monitor the light conditions your ficus bonsai tree receives and adjust its placement accordingly.


When deciding where to place your bonsai tree, there are a few factors to consider. Firstly, ensure that it’s placed in an area with consistent temperature and humidity levels. Avoid placing it near drafty windows, air conditioning vents, or radiators, as sudden temperature fluctuations can stress the tree. Additionally, keep your bonsai tree away from strong winds, as they can damage the delicate branches.

Artificial Lighting

If you’re growing your ficus bonsai tree indoors or in a location without adequate natural light, artificial lighting can be a great solution. LED grow lights are a popular choice as they provide the specific spectrum of light that plants need for photosynthesis. Place the lights close to the bonsai tree, ensuring they cover the entire canopy evenly. Keep the lights on for 10-12 hours a day to supplement the lack of natural light effectively.



Proper watering is key to maintaining the health of your ficus bonsai tree. The frequency of watering depends on various factors, including the season, pot size, and environmental conditions. As a general rule, water your ficus bonsai when the top inch of soil feels dry. Remember, it’s better to slightly underwater than to overwater, as ficus trees are susceptible to root rot.

Watering Techniques

To water your ficus bonsai tree thoroughly, immerse the pot in a container of water for a few minutes. This will allow the soil to absorb moisture, ensuring the roots receive adequate hydration. Afterward, allow the excess water to drain away completely before returning the bonsai to its display location.


Proper drainage is crucial for the health of your ficus bonsai tree. Ensure that the pot has sufficient drainage holes to allow excess water to escape. Consider using a well-draining bonsai soil mix, such as a combination of akadama, pumice, and lava rock, to promote proper drainage. Avoid using regular garden soil, as it retains too much water and can lead to root rot.


Ficus bonsai trees thrive in humid environments. To maintain the necessary humidity, you can mist the foliage regularly or use a humidity tray. A humidity tray is a shallow dish filled with water and pebbles. The bonsai pot sits on top of the pebbles, allowing water to evaporate and create a humid microclimate around the tree. Monitor the humidity levels and adjust as necessary to keep your ficus bonsai tree happy and healthy.


Fertilizer Selection

Proper fertilization is essential for the growth and vitality of your ficus bonsai tree. Choose a well-balanced, slow-release bonsai fertilizer or an organic option. Look for a fertilizer with a ratio of approximately 10-10-10 or 14-14-14, as this will provide a good balance of essential nutrients.

Feeding Schedule

During the growing season, which typically spans from spring to early fall, fertilize your ficus bonsai tree every two weeks. Follow the recommended dosage provided by the fertilizer manufacturer. In winter, reduce the frequency to once every 4-6 weeks, as the tree’s growth slows down.

Organic vs. Synthetic Fertilizer

Both organic and synthetic fertilizers have their benefits. Organic fertilizers, such as fish emulsion or seaweed extract, provide slow-releasing nutrients and improve the overall soil quality. On the other hand, synthetic fertilizers allow for more precise nutrient control and faster results. Ultimately, the choice between organic and synthetic fertilizers depends on personal preference and the specific needs of your ficus bonsai tree.

Nutrient Deficiencies

Keep an eye out for signs of nutrient deficiencies in your ficus bonsai tree. Yellowing leaves, stunted growth, or leaf drop can indicate a lack of essential nutrients. If you notice any of these symptoms, adjust your fertilization routine accordingly. However, be cautious not to over-fertilize, as this can lead to nutrient burn and cause further damage to the tree.

Temperature and Climate

Ideal Temperature

Ficus bonsai trees prefer a warm climate with temperatures ranging between 60°F and 75°F (15°C to 24°C). They can tolerate slightly lower temperatures during the winter dormancy period, but prolonged exposure to frost or extreme cold can be detrimental.

Cold Protection

If you live in an area with cold winters, it’s important to protect your ficus bonsai tree from freezing temperatures. Move the tree indoors or to a sheltered location, such as a garage or basement, when temperatures drop below freezing. You can also wrap the pot in insulation material or use a frost blanket to provide additional protection.

Heat Protection

During hot summer months, when temperatures rise above 90°F (32°C), your ficus bonsai tree may require extra care. Ensure that the tree is placed in a shaded area to protect it from direct sunlight, which can scorch the leaves. Mist the foliage regularly to provide some relief from the heat and maintain proper humidity levels.

Climate Considerations

When choosing a ficus bonsai tree, consider the climate of your region. Ficus benjamina, also known as the weeping fig, is more suitable for warmer climates, while Ficus microcarpa, or the Chinese banyan tree, is more cold-hardy. Select a ficus variety that is better adapted to your local climate to ensure a successful and thriving bonsai tree.
