Hi-Yield Iron Sulfate Granules
Best soil supplement for gardeners seeking deep green lawn color.
This is the quickest fix for yellowing, chlorotic leaves, effectively greening up your garden by correcting iron deficiencies and lowering soil pH. It’s a powerful tool for acid-loving plants, but be careful where you spread it—the granules will permanently stain concrete and stone surfaces if you aren't precise.
