Why does your Rhododendron mucronatum have drooping leaves? Diagnose the cause and fix it with our step-by-step guide.
As an evergreen shrub with relatively shallow root systems, R. mucronatum is highly sensitive to moisture fluctuations; lack of water causes a loss of turgor pressure in the leaves.
Overly saturated, poorly draining soil promotes fungal pathogens that attack the roots of Rhododendrons, preventing the plant from absorbing water despite high soil moisture.
If grown in containers, a dense mass of roots can prevent new growth from accessing nutrients and water, leading to systemic drooping during warmer periods.
Extreme heat or sudden temperature fluctuations can cause R. mucronatum to wilt as a defense mechanism to reduce transpiration surface area.
