Why does your Kalanchoe blossfeldiana Don Amador have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Kalanchoe blossfeldiana is highly sensitive to sudden temperature fluctuations. Exposure to cold drafts from windows or air conditioning units can trigger an immediate stress response resulting in leaf abscission.
Excessive moisture in the substrate leads to anaerobic conditions in the roots. As the root system begins to decay from rot, it can no longer support foliage, causing the plant to shed leaves to conserve energy.
While 'Don Amador' thrives in bright light, a sudden move to a low-light area prevents the succulent leaves from performing photosynthesis efficiently. The plant drops older leaves to prioritize survival of new growth.
Sucking insects like scale or mealybugs drain the sap from the succulent leaves of Kalanchoe. Severe infestations can weaken the plant's vascular system enough to cause rapid leaf drop.
