J. Arthur Bowers Hydrangeas Colourent 500g. Hydrangeas flower in late summer and the colour often depends on the pH of the soil. Acid soils produce blue flowers, alkaline soil produces pink. J Arthur Bower's Hydrangea Colourant can influence the colour when added to the soil. Containing a combination of iron and aluminium salts, the colourant acidifies soil to provide the condition hydrangeas require to produce blue blooms. A pale pink bloom will become blue and a darker pink variety will turn mauve-blue. Please note that White blooms will not change colour.
