If you’ve noticed that your outdoor bonsai tree has turned yellow, there are a few possible reasons for this change in color. Bonsai trees require specific care and attention, and any deviation from their optimal conditions can result in leaf discoloration. Understanding the potential causes of yellowing leaves can help you address the issue and restore your bonsai tree’s health.
One possible reason for yellowing leaves is overwatering. Bonsai trees require a delicate balance of moisture, and excessive watering can lead to root rot. When the roots are unable to properly absorb nutrients and oxygen from the soil, the leaves may turn yellow as a sign of distress.
On the other hand, underwatering can also cause leaf yellowing. When a bonsai tree lacks sufficient water, it becomes dehydrated, which can result in the yellowing and eventual shedding of leaves. To prevent underwatering, it is important to regularly check the moisture levels in your bonsai tree’s soil and water accordingly.
Another potential cause of yellowing leaves is improper lighting conditions. Bonsai trees thrive in bright but indirect sunlight. If your bonsai tree is not receiving enough light or is exposed to direct sunlight for extended periods, it may exhibit yellowing leaves as a response to stress. Adjusting the positioning of your bonsai tree or providing shade during the hottest part of the day can help maintain the ideal lighting conditions.
