Hi-Yield Iron Plus Soil Acidifier

The primary indicator is iron chlorosis, which manifests as yellowing leaves while the veins remain green. If your soil is alkaline or calcareous, your plants may struggle to absorb necessary nutrients, leading to this discoloration and stunted growth.

Hi-Yield Iron Plus is designed to be non-burning when applied according to the label directions. However, it is always best to follow the recommended application rates to ensure you are treating the soil safely and effectively.

This is a fast-acting, pelletized formula designed to break down and begin working relatively quickly. While exact timing depends on soil moisture and environmental conditions, you should start to see an improvement in leaf color and plant vigor as the pH balances and iron becomes available.

This product is versatile and safe for use on lawns, trees, and shrubs suffering from iron chlorosis. Because it is specifically formulated to lower pH in alkaline and calcareous soils, it is most effective for plants that thrive in slightly acidic conditions.

A single 20-pound bag of Hi-Yield Iron Plus provides coverage for up to 2,500 square feet. Be sure to measure your target area beforehand to ensure you have enough product for a complete and uniform application.
