Why does your Citrus meyeri have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Excessive moisture or poor drainage causes fungal pathogens to attack the root system of Meyer Lemons, leading to an inability to transport water and resulting in sudden leaf senescence.
Meyer Lemons are sensitive to temperatures below 50°F (10°C); sudden exposure to cold drafts or frost causes the tree to shed leaves as a defense mechanism.
If the soil dries out completely, the tree enters survival mode and sheds leaves to reduce transpiration and prevent total hydraulic failure.
A lack of nitrogen prevents the tree from maintaining chlorophyll levels, leading to chlorosis followed by premature leaf drop.
