Why does your Yellow Zantedeschia Aethiopica have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Excessive soil moisture or poor drainage in Callas leads to fungal pathogens attacking the tuberous roots. This disrupts water transport, causing the plant to shed foliage rapidly as it fails to sustain leaf hydration.
Yellow Calla Lilies are sensitive to sudden drops in temperature or frost. Exposure to drafts or temperatures below 10°C (50°F) causes the plant to enter a defensive state, resulting in immediate leaf senescence and drop.
While Callas love moisture, extreme drying of the potting medium causes the leaves to wilt and eventually detach from the rhizome. This is often a survival mechanism when the plant can no longer maintain turgor pressure.
A prolonged lack of nitrogen prevents the plant from maintaining chlorophyll and structural integrity in new growth. While usually gradual, severe deficiency can lead to widespread leaf loss during periods of high metabolic demand.
