Will vinegar kill centipede grass

Yes, vinegar can kill centipede grass, particularly if it's a high-concentration vinegar (like horticultural vinegar). The acetic acid in vinegar acts as a desiccant, damaging the grass's cells and leading to its death. However, using vinegar may also harm surrounding plants, so it should be applied carefully and selectively. For effective weed control, consider using vinegar when the grass is actively growing and the weather is warm.
