Why does your Hydrangea macrophylla Magical Cerise have drooping leaves? Diagnose the cause and fix it with our step-by-step guide.
Hydrangeas have large, thin leaves with high transpiration rates, making them extremely sensitive to dry soil. When the substrate dries out, the plant loses turgor pressure, causing the leaves to wilt rapidly.
Excessive moisture in the potting medium prevents oxygen from reaching the roots, leading to fungal decay. As roots die, they can no longer transport water to the foliage, causing symptoms that mimic dehydration.
High afternoon temperatures can cause the leaves of 'Magical Cerise' to wilt even if soil moisture is adequate, as a mechanism to reduce surface area for transpiration. This often occurs during midday sun exposure.
A lack of nitrogen can weaken the structural integrity of the stems and leaves, leading to a limp appearance. This is often accompanied by chlorosis (yellowing) of older leaves.
