Why does your Aeonium canariense 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 and stems; excessive moisture causes the root system to decay, leading to a sudden inability to transport water to the rosette, resulting in leaf drop.
While Aeoniums are resilient, sudden drops in temperature or frost can damage the cellular structure of the leaves, causing the plant to shed them rapidly to protect the core.
In high heat, Aeonium can enter a dormant-like state to conserve moisture; if the soil dries out too quickly during heatwaves, the plant may drop older leaves to reduce transpiration.
A lack of essential nutrients can weaken the attachment points of the leaves, making them prone to falling off even with minimal physical disturbance.
