Why does your Aeonium arboreum have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Aeoniums are succulents that store water in their leaves; excessive moisture causes the roots to decay, preventing the plant from supporting its foliage. As the root system fails, the plant sheds lower leaves rapidly to conserve remaining resources.
While Aeonium arboreum is hardy, extreme heat waves or sudden freezing temperatures can cause physiological shock. Sudden drops in temperature lead to cellular breakdown in the leaves, resulting in rapid shedding.
Sap-sucking insects like scale or mealybugs can congregate at the base of the rosette and stem. By draining the plant's vascular fluids, they weaken the structural integrity of the leaf attachments.
A lack of essential macronutrients, particularly nitrogen, can cause a succulent to enter a semi-dormant state where it sheds older leaves to prioritize new growth. This often happens if the soil is depleted or lacks organic matter.
