How does Lawn Dethatcher work?

Our liquid dethatcher is formulated to energize soil microbes that naturally feed on organic materials, including grass clippings and other lawn waste, to break down thatch. With our proprietary blend of organic biostimulants, fulvic and humic acids, and carbohydrate-rich molasses, our dethatcher promotes microbial activity, which enhances penetration and drainage in your lawn.
