Hydrangeas are naturally pink, but where the soil contains iron or aluminium salts they will produce blue flowers . Where neither is naturally available and you want blue flowers, the Vitax Colourant is the solution. Pale pink varieties tend to blue best, with the darker pink varieties producing mauve/blue flowers. Mix the colourant with the soil when planting pot or outdoor hydrangeas or dissolve in water and apply. Always read the label on your purchased product before use.
