Cultivation
Hydrangea macrophylla (Thunb.) Ser.
Hydrangea macrophylla is characterized by high transpiration and sensitivity to water stress, requiring consistent substrate moisture without waterlogging.
In the reference 57 varieties crop Bigleaf hydrangea, where this is mentioned in the description.
Due to the large leaf surface area, the crop is prone to intense evaporation, which at temperatures above 30°C leads to rapid wilting even with adequate moisture. The optimal regime involves keeping the substrate constantly moist, with daily water consumption in container-grown plants potentially reaching 300 ml per plant, depending on the growth stage and light intensity.
Applying restricted irrigation during specific growth phases is an effective technique for controlling habitus and obtaining more compact specimens. The pH of the irrigation water is critically important, as it determines the availability of aluminum in the substrate and directly influences the color of the inflorescences. To prevent fungal diseases, it is recommended to use root zone irrigation or drip irrigation systems that avoid wetting the foliage.
