Why does your Zantedeschia Allure have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Zantedeschia 'Allure' is highly susceptible to rhizome rot if the growing medium remains saturated. Excess water deprives the roots of oxygen, leading to chlorosis (yellowing) starting from the older leaves.
As a heavy feeder during its growing season, 'Allure' requires consistent nitrogen levels to maintain chlorophyll production. A lack of nitrogen causes older leaves to turn uniformly yellow before eventually dying.
Calla Lilies are tropical perennials that thrive in warmth; sudden drops in temperature can trigger a physiological response where the plant breaks down chlorophyll to protect its core.
While 'Allure' can tolerate partial shade, insufficient light prevents the plant from performing enough photosynthesis to sustain its large, lush foliage, leading to pale or yellowing leaves.
