Why does your Aglaonema commutatum have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Aglaonema is highly susceptible to moisture buildup; excessive water saturates the soil, depriving roots of oxygen and leading to fungal pathogens like Pythium. This prevents the plant from transporting nutrients, resulting in chlorosis (yellowing) often starting with older leaves.
A lack of nitrogen prevents the synthesis of chlorophyll, causing older leaves to turn uniformly yellow. In Aglaonema, this often manifests as a pale, washed-out appearance across the foliage.
While Aglaonema thrives in low light, extreme darkness prevents photosynthesis, leading to a loss of pigment and yellowing. Conversely, sudden exposure to direct sunlight can cause solar bleaching and chlorosis.
Aglaonema are tropical plants that dislike temperatures below 60°F (15°C). Sudden drops in temperature or exposure to cold drafts can cause the cellular structure of the leaves to collapse, resulting in yellowing.
