This colourant easily absorbs nutrients and nitrogen for greener leaves. For best results, use with plants growing in acid soils. If the soil is naturally alkaline, use ericaceous compost or double the application rate. This product is a combination of iron and aluminium salts that acidifies the soil to produce blue flowers and contains potassium to boost flowering.
This guide is for gardeners looking to enhance the color of their hydrangeas, specifically those with pink varieties wishing to achieve blue blooms. Westland Hydrangea Colourant is a simple-to-use product that alters soil acidity, leading to color changes in your hydrangeas. However, it's most effective in slightly acidic soil; alkaline soils may require adjustments.
