Why does your Euphorbia Eritrea have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Euphorbia Eritrea is a succulent native to arid regions and is highly sensitive to sudden drops in temperature or cold drafts. Rapidly falling temperatures cause the plant to enter a stress response, leading to the shedding of leaves to conserve moisture.
Excessive moisture in the substrate prevents oxygen from reaching the roots, leading to fungal decay. As the root system fails, it can no longer support the foliage, resulting in sudden leaf senescence and drop.
This species requires high light intensity to maintain its metabolic processes. A sudden change in environment, such as being moved to a shaded corner, can trigger the plant to shed leaves that it can no longer support via photosynthesis.
Sap-sucking insects like scale or mealybugs can rapidly deplete the plant's energy reserves by feeding on the succulent tissues. This nutritional stress often manifests as sudden leaf loss.
