Why does your Echeveria prolifica 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 Phytophthora to attack the roots of Echeveria prolifica. As roots decay, they can no longer transport water to the leaves, leading to a sudden loss of turgor and leaf abscission.
Echeveria prolifica is sensitive to sudden drops in temperature, especially below 50°F (10°C). Rapid changes in ambient temperature can trigger a stress response that causes the plant to shed older leaves to conserve energy.
Small, sap-sucking insects like mealybugs congregate at the leaf axils of Echeveria. Their feeding weakens the connection between the leaf and the stem, eventually causing leaves to drop prematurely.
A lack of essential macronutrients like nitrogen can cause the plant to undergo senescence, where it reallocates nutrients from older, lower leaves to new growth at the apex.
