Why does your Anthurium andraeanum Turenza have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Anthuriums are highly sensitive to stagnant water; excessive moisture leads to anaerobic conditions in the substrate, causing root decay which prevents oxygen and nutrient transport to the foliage.
A lack of nitrogen often manifests as uniform yellowing across older leaves, while magnesium deficiency can cause chlorosis between leaf veins in 'Turenza' varieties.
As tropical plants, Anthuriums require high humidity; when air is too dry, the plant undergoes physiological stress that can cause foliage to lose chlorophyll and turn yellow.
While they love bright light, direct afternoon sun can overwhelm the 'Turenza' leaves, causing the chlorophyll to break down and resulting in yellow or bleached patches.
