Why does your Hydrangea chinensis have drooping leaves? Diagnose the cause and fix it with our step-by-step guide.
Hydrangeas have large, thin leaves with high transpiration rates; when soil moisture is insufficient, the plant quickly loses turgor pressure. This leads to visible wilting even if the soil was recently moist.
Excessive moisture in heavy soil suffocates the roots, preventing them from absorbing water. This paradoxically causes the leaves to droop as if the plant were thirsty.
High afternoon temperatures can cause the leaves to wilt as a defense mechanism to reduce surface area for evaporation. This usually occurs during peak sunlight hours and recovers in the evening.
Soil-borne oomycetes can attack the root system of Hydrangea chinensis, physically destroying the vascular tissue responsible for water transport.
