Vitax Hydrangea Colourant - 250g

Transform pink hydrangeas into striking blue blooms on your next landscaping project with Vitax Hydrangea Colourant 250g. Whether you are working on a client garden or upgrading a domestic border, this treatment delivers reliable results by supplying the iron or aluminium salts that naturally trigger blue flowers. Pale pink varieties achieve the best blue, while darker pinks turn to mauve or blue. It works effectively in both acid and alkaline soils, though you should double the proportions if the soil is alkaline.

Suitable for both pot-grown hydrangeas and outdoor plants, the formula dissolves readily in a little hot water and mixes directly into the soil where the root system develops. Once established, simply dilute as directed and water weekly during the growing season. Always keep out of reach of children and wear protective gloves and eye protection where possible during use.
