Why does your Zantedeschia Captain Beretta have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Zantedeschia are susceptible to Phytophthora if the rhizome remains in waterlogged soil. Excess moisture prevents oxygen from reaching the roots, leading to yellowing foliage as the plant's vascular system fails.
A lack of available nitrogen prevents the production of chlorophyll in the large leaves of 'Captain Beretta'. This typically manifests as a uniform yellowing starting from the older, lower leaves.
Calla Lilies are sensitive to sudden drops in temperature. Cold drafts or temperatures below 55°F (13°C) can cause the metabolic processes to slow down, resulting in chlorosis and wilting.
While 'Captain Beretta' can tolerate partial shade, insufficient light levels prevent the plant from maintaining its energy reserves. This leads to pale, yellowish leaves as the plant struggles to photosynthesize.
