Cultivation

Container Cultivation of Smooth Hydrangea

Hydrangea arborescens L.

Growing Hydrangea arborescens in containers relies on using compact cultivars and annual spring pruning of current-season shoots. This method differs from other hydrangea species due to high winter hardiness and the fact that inflorescence color is independent of substrate pH.

In the reference 14 varieties crop Smooth hydrangea, where this is mentioned in the description.

For container cultivation of Hydrangea arborescens, compact bred cultivars adapted to confined spaces are preferred. Plants require a high-quality, well-drained substrate based on peat and bark, while maintaining stable moisture levels is critical, as the species is sensitive to drying out.

The cultivation technology involves mandatory pruning in late winter or early spring, which stimulates the growth of new shoots upon which flowering occurs. Unlike Hydrangea macrophylla, Hydrangea arborescens possesses high winter hardiness across a wide range of zones and does not require soil acidity modification to achieve its characteristic inflorescence color.
