Cultivation
Hydrangea macrophylla (Thunb.) Ser.
A cultivation method for Hydrangea macrophylla in containers, allowing for the management of wintering for non-hardy varieties and the regulation of inflorescence color by adjusting substrate acidity. It is a key tool for preserving flower buds formed on the previous year's growth.
In the reference 544 varieties crop Bigleaf hydrangea, where this is mentioned in the description.
The container method provides mobility for Hydrangea macrophylla, which is critical for regions with harsh climates: moving the plant indoors for the winter prevents shoot frost damage and ensures annual flowering. In a limited volume of substrate, it is easier for an agronomist to control the pH level, which directly affects the intensity and shade of blue or pink inflorescences.
The root system of the crop is highly sensitive to overheating and excessive moisture; therefore, it requires placement in partial shade and the use of containers with a well-developed drainage system. The technology involves phased repotting as the root ball fills the container, as "restricted" conditions promote more abundant flowering; however, it is important to avoid planting in excessively large containers to prevent waterlogging and the risk of root rot.
