Why does your Zantedeschia Captain Fargo have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Excessive moisture in the substrate causes fungal pathogens to attack the rhizome of the Zantedeschia, leading to sudden foliage collapse. This prevents the plant from transporting water to the leaves, causing them to detach rapidly.
Calla Lilies are sensitive to sudden drops in temperature, especially drafts from air conditioning or windows. A sudden thermal shift can trigger an immediate physiological stress response resulting in leaf abscission.
While they like moisture, letting the soil dry out completely can cause Zantedeschia to enter a survival mode where it sheds leaves to conserve water. This is often seen when the rhizome's ability to hold moisture is compromised.
A lack of available nitrogen prevents the maintenance of chlorophyll and structural integrity in new growth, making leaves prone to dropping during periods of low light or high metabolic demand.
