Why does your Aloe marlothii have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Aloe marlothii is a succulent that requires well-draining soil; excessive moisture causes the roots to suffocate and rot, leading to the sudden detachment of lower leaves. As the root system fails, it can no longer support the plant's hydraulic pressure.
While mature Aloe marlothii can tolerate some cold, a sudden drop below freezing temperatures causes cellular rupture in the leaves. This rapid destruction of cell walls leads to the softening and eventual dropping of affected foliage.
A prolonged lack of essential macronutrients can cause the plant to undergo senescence, where it sheds older, lower leaves to redirect resources to the new growth at the apex. This is often a gradual process but can appear sudden if soil reserves are depleted.
Heavy infestations of sap-sucking insects like scale or mealybugs drain the plant's energy and compromise structural integrity. The physiological stress from significant fluid loss can trigger a defensive leaf drop response.
