Using Aged Horse Manure: Application Tips and Herbicide Warning

One-year-old horse manure won't burn plants if applied <1 inch deep and kept 3 inches from stems. Critical caution: verify the source farm doesn't use persistent herbicides like Grazon on pastures—these survive in manure and kill garden vegetables. Clean aged manure is garden gold; contaminated manure is garden disaster.
