Southern Ag Iron Granules is a 5 lb bag of granular iron fertilizer, 30% iron, used to acidify soil, lower pH and correct high alkalinity. It is aimed at lawns and acid-loving plants such as tropicals, with lower rates for sandy soils and higher rates for heavy soils. The bag covers about 100 square feet of lawn. At $13.72 at Everglades Farm as of November 6, 2026, it is the lowest of four new prices and a cheap way to treat iron chlorosis on a small area.
