Description
Our Westland Hydrangea Colourant allows you to easily change the colour of your hydrangea flowers from pink to blue to complement your existing garden colour scheme.
Made from a combination of iron and aluminium salts, the powder acidifies soil to make hydrangea flowers bloom in vibrant blue. Darker pink varieties will turn a deep mauve blue. The colourant easily absorbs nutrients, as well as nitrogen to enhance the gorgeous green of the plant’s leaves. It also contains potassium to boost flowering and create full, lively flowers.
When using Westland Hydrangea Colourant, use plants growing in acid soils to obtain the best results. Use ericaceous compost where the soil is naturally alkaline and alternatively, double the application rate.
