The Science

Mulch Lawn Clippings and Leaves for Better Lawns,

Returning valuable nutrients and organic matter to soil and can even help prevent weeds.

Who loves lugging a heavy bag of lawn clippings to the compost pile or yard waste bin, or endlessly raking leaves in the fall? Pretty much nobody, that’s who. Fortunately, for the sake of aching backs and nutrient-hungry lawns, it’s best to forgo the bag and opt to mulch lawn clippings and leaves instead.

Each little bit of plant material is full of nutrients and being organic matter, when left in place, can improve the overall health of the soil which in turn, better supports the turf and potentially decrease inputs.

“In the lawncare industry we’re realizing that rather than feed the lawn synthetically with fertilizers we can choose to do it more organically by mulching grass clippings and leaving them on the lawn to sift in,” says Richard Hentschel, University of Illinois horticultural extension educator. “Leaving clippings on the lawn provides the equivalent of 1 pound of nitrogen per 1,000 square feet of lawn. That’s nitrogen you didn’t have to buy and apply.” Removing the clippings means also removing those nutrients from the system.
