Why does your Sedum morganianum have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
This succulent is highly susceptible to fungal pathogens like Phytophthora when the substrate remains saturated. Excess moisture causes the roots to decay, disrupting the plant's ability to transport water, leading to a rapid loss of turgor pressure and leaf abscission.
Burro's Tail is sensitive to sudden shifts in environment, particularly frost or extreme heat. Rapid temperature fluctuations cause the plant to enter a stress response, resulting in the shedding of its fleshy leaves to conserve moisture.
Soft-bodied insects like mealybugs feed on the sap of Sedum leaves, weakening the attachment point between the leaf and the stem. A heavy infestation can cause the plant to shed leaves rapidly as it loses nutrients.
Long-term lack of essential minerals like magnesium or nitrogen can weaken the cellular structure of the succulent. While usually a slower process, extreme depletion can lead to the plant shedding older leaves to prioritize new growth.
