Hydrangea Colourant 250g
A quick and easy treatment to turn your pink hydrangeas to blue.
Made from iron and aluminium salts, this colourant acidifies the soil to make hydrangea flowers bloom in blue. Pale pink hydrangeas turn blue with dark pink hydrangeas turning mauve/blue.
Ideal for potted hydrangeas and for hydrangeas in the garden. Simply dissolve in a little hot water and mix with the soil around the shrub taking care to avoid the foliage. After establishment, dilute the hydrangea colourant as directed on the pack.
Please note: white flowers will not change colour and some pink hydrangeas are bred to keep their colour in all soil conditions so will remain unchanged.
