Sulphate of Iron 1.5kg is a ready-to-use soil treatment designed for ericaceous and acid-loving plants, providing immediately available iron to support healthier growth. It helps make soil more acidic, improving nutrient availability in soils that may be too alkaline for plants such as rhododendrons, camellias, azaleas, and hydrangeas.
By enriching the soil with iron and helping unlock essential nutrients, it supports stronger development and helps reduce deficiency issues linked to higher soil pH. It can be applied regularly to help maintain suitable conditions for acid-loving plants.
