Why does your Echeveria pulvinata Frosty have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Excessive moisture in the substrate causes fungal pathogens like Pythium to attack the roots, preventing water uptake and causing leaves to detach easily from the stem. This is the most common cause of sudden leaf drop in Echeveria.
Echeveria pulvinata is sensitive to sudden temperature fluctuations, especially cold drafts or frost. Rapid drops in temperature can cause cell wall collapse, leading to the plant shedding leaves as a stress response.
Small, white, cottony insects known as mealybugs feed on the sap of the Echeveria, weakening the plant's structural integrity and causing leaves to drop. Their feeding disrupts the nutrient flow to individual leaf nodes.
A significant lack of essential micronutrients, particularly nitrogen or magnesium, can cause the plant to undergo senescence, where it sheds older leaves to redirect resources to new growth.
