Vitax Hydrangea Colourant

Changes pink hydrangeas to blue!

Hydrangeas growing in the presence of iron or aluminium salts will tend to change colour and produce blue flowers. Varieties naturally pale pink tend to blue best, the darker pink varieties turning to mauve/blue.

Best results are obtained with plants growing in acid soil.

Keep out of reach of children and pets. Read instructions carefully before use.
