Vitax Hydrangea Colourant is a specialised treatment designed to help turn pink hydrangea flowers to shades of blue or mauve, depending on the variety. It works by introducing aluminium salts into the soil, which influence petal colour in acid conditions.

This colourant is ideal for gardeners looking to adjust their plant's appearance and is suitable for both container-grown and outdoor hydrangeas. For best results, use on pale pink varieties in acid soil. If your soil is more alkaline, double the dose to improve effectiveness.
