Water

Proper watering is fundamental to the well-being of the Japanese hydrangea vine.

Appropriate fertilization can enhance the growth and flowering capacity of the Japanese hydrangea vine. A balanced, slow-release fertilizer formulated for flowering climbers can be applied in spring, following the manufacturer’s instructions. It is important to avoid over-fertilization, which can lead to excessive vegetative growth at the expense of flowering.
