Identifying the Problem

When reviving a struggling bonsai tree, it’s crucial to first identify the underlying issue. This section will discuss common problems and their signs:


Underwatering can lead to a weak and wilting bonsai. Signs of insufficient watering include dry soil, drooping leaves, and leaves turning yellow or brown. To fix this issue, adjust the watering schedule to ensure consistent moisture for the tree’s specific needs.


Overwatering can be just as harmful to a bonsai tree. Symptoms include yellowing leaves, rotting roots, and mold growth. Be cautious not to overwater, and always check that the soil drains properly to prevent waterlogging.

Lack of Sunlight

Bonsai trees require adequate sunlight for optimal growth. A tree not receiving enough light may exhibit weak or spindly growth, elongated internodes, and pale leaves. Ensure that your bonsai receives the recommended amount of sunlight for its species.

Pests and Diseases

Pests and diseases can weaken a bonsai tree and compromise its health. Common symptoms include discolored leaves, visible insects, or fuzzy white spots on leaves or branches. If your tree is infected, take appropriate measures such as using insecticides or fungicides, depending on the issue. For example, if there are signs of mold, gently dab the infected area with a cotton ball dipped in rubbing alcohol, as suggested by WikiHow.

Steps to Revive a Bonsai Tree

Assess the Bonsai Tree

Begin by carefully examining your bonsai tree to identify any signs of decay or disease, as well as any damaged or dead parts that need attention. This evaluation will give you a better understanding of the necessary steps to take in order to revive the tree.

Prune Damaged Roots

Remove any dead or diseased roots using a pair of sharp pruning shears, taking care not to damage healthy roots in the process. Once you’ve finished pruning, keep the healthy roots moist by either submerging them in water or using another moisture-retention method.

Repot the Bonsai Tree

Choose a suitable pot for your bonsai tree and prepare it with the correct soil mixture based on your tree’s specific needs. After repotting, immerse the bonsai in a large container of water, such as a sink or bucket, for a brief soaking to ensure adequate hydration.

Water and Fertilize Properly

It is essential to water your bonsai tree thoroughly, allowing enough time for the soil to absorb the moisture before watering again. Additionally, be sure to provide proper fertilization to promote healthy growth and recovery.

Adjust Lighting Conditions

Place your bonsai tree in a location that receives at least five hours of sunlight daily, with some trees requiring direct sunlight while others need indirect light to prevent leaf burning. Make adjustments to the lighting conditions as needed according to your tree’s specific requirements.

Monitor and Treat Pests and Diseases

Keep a close eye on your bonsai tree and address any pest or disease issues that may arise. This will not only help in the tree’s recovery process but also prevent future problems from developing.

Maintaining a Healthy Bonsai Tree

Proper Watering Techniques

Watering is one of the key aspects of keeping your bonsai tree healthy. Ensure the soil is consistently moist, but not overly wet. A good approach is to water your tree, wait a few minutes, and then water it again, making sure the entire soil has a chance to absorb the moisture.

Appropriate Soil Mix

Using the right soil is crucial for bonsai health. It is recommended to use a bonsai potting soil specifically designed for bonsai trees. This type of soil helps retain water and provides good drainage, which is crucial for your tree’s growth.

Sunlight Requirements

Bonsai trees require adequate sunlight for growth and overall health. When bringing your bonsai indoors, make sure it gets enough natural light. If possible, place it near a window where it can receive plenty of sunlight.

Regular Pruning

Pruning is an essential component of bonsai tree care. Remove dead foliage with sharp pruning shears to help your tree maintain its shape and health. Make sure to remove all dead leaves to ensure proper growth.

Pest and Disease Prevention

Keeping your bonsai tree free of pests and diseases is essential for long-term health. Regularly examine the tree for any signs of infestations or infections. If you notice issues with the roots while repotting, remove the diseased roots using clean pruning shears and trim away any affected foliage.
