Why does your Citrus aurantifolia have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Overwatering or poor drainage in citrus soil creates anaerobic conditions that promote Phytophthora species, causing roots to decay and the tree to shed leaves rapidly to reduce transpiration.
Key Limes are highly sensitive to cold; exposure to temperatures below 50°F (10°C) can cause the tree to enter a physiological shock state, resulting in sudden leaf abscission.
Rapid dehydration causes the citrus tree to shed leaves as a survival mechanism to prevent further moisture loss through the foliage.
Severe lack of nitrogen prevents the tree from maintaining chlorophyll, leading to chlorosis followed by premature leaf drop.
