Product Information
Why Use Fertilome Soil Acidifier Plus Iron
Soil Acidifier Plus Iron is designed to help reduce alkalinity in alkaline soils while supplying the trace elements needed by acid-loving plants.
High pH soils often prevent plants from absorbing iron and other micronutrients, leading to yellow leaves, stunted growth, and chlorosis.
This formula lowers soil pH and delivers iron, sulfur, magnesium, zinc, and copper—supporting deep green foliage, improved nutrient uptake, and stronger overall plant performance.
