Using Brake Lathe Iron Filings on Bermudagrass

Iron Source for Greening

Question: Is it safe to apply iron filings from a brake lathe to bermudagrass for color?

Answer

Yellow bermudagrass often stems from alkaline soil locking up iron. Chelated iron fertilizers work only if pH is lowered. Brake‑lathe iron (iron oxide) is safe but slow‑release. Combine with elemental sulfur to lower pH. Best practice: soil test first, adjust pH, then apply iron.
