Going to extremes to get rid of weeds? Stop fighting, start Preening! Use Preen Garden Weed Preventers and stop weeds before they start.

Spraying and pulling the weeds that have invaded your garden is hard work. You can spray them, burn them, and dig them out, but you’ll need to do it over and over again. Preen creates an invisible weed-fighting barrier beneath the soil surface that keeps weed seeds from growing and forming roots. No roots, no weeds, no weeding—it’s that simple.
