Reasons and Solutions for Begonia rex Leaves Turning RedWith the arrival of spring, many flowers begin to bloom in abundance. Among them, Begonia rex is deeply loved by gardening enthusiasts for its unique flower colors and elegant posture. Recently, many gardeners have reported that the leaves of their Begonia rex plants have turned red. This not only affects their ornamental value but may also pose a threat to the plant's health. This article will analyze the reasons for Begonia rex leaves turning red and provide corresponding solutions.
Reasons for Begonia rex Leaves Turning Red1. Insufficient Light
Begonia rex thrives in a sunny environment. If left in a dark and humid place for a long time, the leaves are prone to turning red. This is because insufficient light prevents the leaves from photosynthesizing properly, which in turn affects the plant's growth.
2. Improper Watering
Watering is a crucial part of caring for Begonia rex. Both overwatering and underwatering can lead to leaves turning red. Overwatering can cause root hypoxia, affecting nutrient absorption by the roots; while underwatering will cause the soil to dry out, leading to water deficiency in the leaves.
3. Soil Issues
Soil is the foundation for the growth of Begonia rex. The quality of the soil directly relates to the health of the plant. If the soil is too compacted, has an unsuitable pH, or lacks nutrients, it can cause the leaves to turn red.
4. Pest and Disease Infestation
During its growth, Begonia rex may be infested by pests such as aphids and spider mites. These pests suck nutrients from the plant, causing the leaves to turn red.

Move the Begonia rex to a sunny location, ensuring it receives at least 4 hours of direct sunlight daily. If grown indoors, you can use auxiliary light sources like a desk lamp.
2. Control Watering

3. Improve the Soil
Regularly replace the soil for Begonia rex with a loose, breathable, and well-draining one. Maintain the soil pH between 6.0 and 6.5. You can apply organic fertilizers to supplement the soil's nutrients.

Regularly inspect the plant for pests and diseases, and treat them promptly if found. You can use insecticides and fungicides for prevention and control. Be sure to follow the instructions on the label for correct usage.
