Why does your Zantedeschia Captain Angelo have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Zantedeschia species are sensitive to stagnant water; excessive moisture leads to Phytophthora or Pythium, causing the rhizome to decay and leaves to wilt and drop suddenly. This is common if the potting medium lacks adequate drainage for this cultivar.
Calla Lilies thrive in stable environments; a sudden drop in temperature or exposure to cold drafts can trigger an immediate physiological response resulting in leaf abscission. This is particularly common if the plant is near a window or air conditioning vent.
A lack of available nitrogen prevents the plant from maintaining its large, variegated foliage, leading to chlorosis and eventual leaf drop. This often occurs if the plant has been in the same soil for several growing seasons without fertilization.
High humidity combined with poor airflow can cause Botrytis cinerea, which creates lesions on the leaves that weaken the petiole and cause sudden leaf drop. This is highly prevalent in the dense foliage of variegated cultivars like 'Captain Angelo'.
