Why does your Crassula mesembrianthoides subsp. hispida have drooping leaves? Diagnose the cause and fix it with our step-by-step guide.
As a succulent, this species is highly susceptible to fungal pathogens like Phytophthora when the substrate remains saturated. Excessive moisture suffocates the roots, preventing the plant from transporting water to the leaves, causing them to lose turgor pressure.
In periods of extreme drought, Crassula mesembrianthoides subsp. hispida will intentionally sacrifice leaf turgidity to conserve internal moisture. The leaves appear wrinkled and limp as the plant uses its stored water reserves.
This subspecies is not frost-hardy. Exposure to temperatures near or below freezing can damage cell membranes in the fleshy leaves, leading to rapid loss of structural integrity and drooping.
A lack of available nitrogen prevents the formation of chlorophyll and structural proteins necessary for leaf rigidity. This typically manifests as a general loss of vigor and drooping in new growth.
