Detecting Pesticide Residue in Grass Clippings for Organic Gardens

Using landscaper-sourced grass clippings as mulch is a fantastic way to build sandy soil—but only if they're pesticide-free. There's no cheap, instant field test for residues. The reliable method: send a sample to a reputable agricultural lab (such as A&L Plains Agricultural Laboratory in Lubbock, TX) for a full pesticide screen. Call ahead to discuss the specific analysis you need.

Until you have clean clippings, stick to your own yard waste or certified organic mulch. Building soil health with uncontaminated organic matter is the foundation of a resilient garden.
