Why does your Anthurium andraeanum Alabama have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Anthuriums are highly sensitive to moisture; excessive water in the potting medium deprives roots of oxygen, leading to fungal pathogens like Phytophthora. This prevents the plant from transporting nutrients, causing older leaves to turn yellow.
A lack of nitrogen prevents the synthesis of chlorophyll, which is essential for the bright green color of Anthurium foliage. Nitrogen deficiency typically manifests as uniform yellowing starting from the older, lower leaves.
Anthuriums are tropical plants that require high humidity (above 60%). Low ambient humidity causes physiological stress, which can lead to chlorosis and eventually crispy, yellowed leaf margins.
Exposure to temperatures below 60°F (15°C) can shock the metabolic processes of 'Alabama' Anthuriums. This thermal stress disrupts cellular function, often resulting in yellowing or spotting on the leaves.
