Why does your Zantedeschia Captain Fargo have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Zantedeschia cultivars are highly susceptible to moisture-induced stress. Constant saturation of the rhizome or root system leads to anaerobic conditions, causing the leaves to lose chlorophyll and turn yellow.
As heavy feeders, Calla Lilies require consistent nitrogen levels to maintain their lush green foliage. A lack of nitrogen prevents the formation of chlorophyll, typically starting with older leaves turning pale yellow.
Zantedeschia are tropical/subtropical plants that thrive in warmth. Sudden exposure to temperatures below 50°F (10°C) can cause physiological shock, resulting in rapid leaf yellowing and wilting.
While 'Captain Fargo' can tolerate partial shade, insufficient light prevents the plant from photosynthesizing effectively. This leads to weak, chlorotic (yellow) leaves as the plant struggles to produce energy.
