Product Overview
Aluminium Sulphate Hydrangea Blue is a specialised soil treatment designed to help produce and maintain blue flowers in suitable hydrangea varieties. It supplies aluminium while helping create the acidic soil conditions required for hydrangeas to take up aluminium and develop their characteristic blue colouring.
Best results are achieved when soil pH is checked and adjusted before the flowering period. Maintaining suitably acidic conditions throughout the growing season helps promote consistent blue flower colour.
