Why does your Zantedeschia Captain Maestro have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Zantedeschia are highly susceptible to rhizome rot if the substrate remains waterlogged. Excessive moisture prevents oxygen from reaching the roots, leading to yellowing foliage as the plant can no longer transport nutrients.
The large, lush leaves of 'Captain Maestro' require significant nitrogen for chlorophyll production. A lack of available nitrogen in the potting medium will cause older, lower leaves to turn pale yellow first.
Calla Lilies are tender perennials that thrive in warmth. Sudden drops in temperature or exposure to drafts can trigger a physiological response resulting in chlorosis and drooping leaves.
As the plant completes its blooming cycle and enters dormancy, it naturally reallocates energy from older foliage to the rhizome. This process involves the gradual yellowing of older leaves.
