Begonia Maculata, commonly known as Polka Dot Begonia, is a popular houseplant known for its attractive silver polka dot patterned leaves. However, if you notice your begonia’s leaves turning yellow, this could indicate a problem that needs to be addressed.
Yellowing leaves are a common sign of stress in plants. In this article, we will explore the causes of yellowing leaves and provide solutions to help keep your Begonia Maculata healthy and thriving.
Causes of Yellowing Leaves in Begonia Maculata
Overwatering
Overwatering is one of the most common causes of yellowing leaves in Begonia Maculata. When the plant is overwatered, the roots become waterlogged and are unable to absorb oxygen properly. This results in root rot, which can cause the leaves to turn yellow and eventually fall off.
To avoid overwatering, ensure that the pot has proper drainage holes to allow excess water to drain out. Water only when the top inch of soil feels dry to the touch.
Underwatering
Underwatering is another common cause of yellowing leaves in Begonia Maculata. When the plant is not watered enough, it becomes dehydrated, and the leaves start to wilt and turn yellow.
To avoid underwatering, water your plant regularly and ensure that the soil is evenly moist but not waterlogged. You can also mist the leaves with water to increase humidity around the plant.
Lack of Light
Begonia Maculata requires bright indirect light to thrive. If the plant is not getting enough light, the leaves may start to turn yellow and drop.
To solve this problem, move your plant to a brighter location or place it near a window that receives bright indirect light. You can also consider using artificial grow lights to supplement natural light.
Temperature Stress
Begonia Maculata prefers warm temperatures between 65°F-75°F (18°C-24°C). If the temperature drops below this range, the plant may experience stress, which can cause the leaves to turn yellow and drop.
To avoid temperature stress, keep your plant away from cold drafts or air conditioning vents. You can also use a humidifier to increase humidity around your plant.
Solutions for Yellowing Leaves in Begonia Maculata
Trim Yellow Leaves
If you notice yellow leaves on your Begonia Maculata, prune them off using clean scissors or pruning shears. This will prevent the spread of any fungal or bacterial infections that may be present on the affected leaves.
Repot Your Plant
If your Begonia Maculata is rootbound or has poor drainage, it may be time to repot it. Choose a pot that is slightly larger than the current pot and has proper drainage holes. Use well-draining soil with perlite or sand mixed in for better drainage.
Adjust Watering Schedule
Adjust your watering schedule based on your plant’s needs. Water only when the top inch of soil feels dry to the touch. Avoid overwatering or underwatering your plant.
Provide Adequate Light
Ensure that your Begonia Maculata gets adequate bright indirect light. Move it to a brighter location or use artificial grow lights if necessary.
Maintain Proper Temperature and Humidity
Keep your plant away from cold drafts or air conditioning vents. Use a humidifier to maintain proper humidity levels around your plant.

In conclusion, yellowing leaves in Begonia Maculata can be caused by various factors such as overwatering, underwatering, lack of light, or temperature stress.
