Iron Sulfate
Southern-Gro Fertilizer’s Iron Sulfate is a highly effective solution for preventing and correcting chlorosis, a common problem where plant leaves turn yellow due to iron deficiency. This specially formulated product delivers a potent dose of iron, essential for maintaining the deep green color and overall health of foliage. Beyond addressing iron deficiency, Iron Sulfate also assists in acidifying the soil, creating ideal conditions for acid-loving plants like azaleas, rhododendrons, and blueberries. Whether you’re dealing with yellowing leaves or looking to optimize the soil pH for your plants, Southern-Gro’s Iron Sulfate is an essential tool for gardeners seeking to maintain vibrant, healthy greenery.
