This article will analyze the reasons for the yellowing of Anthurium andreanum leaves and provide corresponding prevention methods.
Reasons for the yellowing of Anthurium andreanum leaves1. Improper water management
Anthurium andreanum prefers a humid environment, but excessive watering or poor drainage can lead to root rot, which can then cause the leaves to turn yellow. Water droplets splashing onto the leaves during watering can easily lead to leaf disease.
2. Insufficient lighting
Anthurium andreanum enjoys diffused light and avoids direct strong sunlight. Prolonged exposure to dark environments can cause leaves to turn yellow due to insufficient photosynthesis.
