Hydrangea Colourant changes pink hydrangeas to blue and dark pink flowers to mauve, working best on acid soils. It also enhances the colour of all lime-hating shrubs. If your soil is alkaline, ericaceous compost should be added plus a double dose of colourant.

Hydrangeas growing in the presence of iron or aluminium salts will tend to change colour and produce blue flowers. Varieties which are naturally pale pink tend to blue best, the darker pink varieties turning to mauve/blue. Best results are seen with plants growing in acid soil. If the soil is alkaline, measurements shown on the packaging need to be doubled.
