Why does your Graptopetalum pentandrum subsp. superbum have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
As a succulent, Ghost Plants are highly susceptible to fungal pathogens like Phytophthora when soil remains saturated. Excessive moisture causes root tissues to decay, breaking the plant's ability to transport water to the leaves, resulting in rapid leaf abscission.
Graptopetalum species are sensitive to extreme temperature fluctuations. Exposure to temperatures near or below freezing causes cell walls in the fleshy leaves to rupture, leading to rapid wilting and leaf drop.
Mealybugs feed on the sap of the Ghost Plant, secreting honeydew and injecting toxins that stress the plant. Severe infestations can cause the plant to shed leaves as it loses vital nutrients and moisture.
While slower than rot, a lack of essential micronutrients in well-draining succulent soil can weaken the structural integrity of the leaf attachments. Over time, this leads to leaves dropping at the slightest touch.
