Why does your Chrysanthemum Castilho White have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Nitrogen is a mobile nutrient; when lacking, the plant translocates it from older leaves to new growth, causing them to turn pale yellow first. In Chrysanthemums, this often results in a loss of the deep green color characteristic of the 'Castilho White' cultivar.
Chrysanthemums require well-draining soil; constant moisture displaces oxygen in the root zone, leading to yellowing foliage. This often precedes stem softening and eventual rot if the medium remains saturated.
High soil pH (alkaline) can prevent the plant from absorbing iron, leading to interveinal chlorosis. In this condition, the leaves turn yellow while the veins remain distinctly green.
While typically known for 'gray mold' on buds, early fungal infections in humid conditions can cause leaves to yellow and wilt. This is common in dense Chrysanthemum varieties with poor air circulation.
