Various chores are synonymous with certain times of year. For example, cleaning a pool is a summertime task. In addition, rare is the instance that Mother Nature forces anyone to break out the snow shovels outside of winter. Raking leaves has long been a task for fall afternoons, but homeowners may be surprised to learn that they might be better off putting their rakes in permanent mothballs.

In the 1990s, turfgrass specialists at Michigan State University began exploring the potential benefits of leaving mulched leaves on a lawn instead of raking them and leaving them for curbside pickup. While the researchers noticed an obvious leaf residue on the lawn after mulching, they noted that it only sticks around for a few days. Eventually, the tiny pieces sifted down into the lawn, ultimately serving to control future weed growth while also providing the lawn with essential nutrients. Over time, researchers noted that homeowners who mulched rather than raked their leaves needed less fertilizer to give their lawns a green look in spring, saving homeowners the effort and cost associated with fertilizing.

Researchers also noted that decomposing pieces of leaves cover up bare spots between turf plants, which have traditionally proven to be excellent spots for weed seeds to germinate. In fact, MSU notes that homeowners can expect a nearly 100% decrease in dandelions and crabgrass after mulching leaves for just three years.

Depending on the type of mower being used, up to 6 inches of leaves can be mulched at a time. Push mowers can handle smaller amounts, though can still be as effective as riding mowers.

Fall may be synonymous with raking leaves. However, homeowners who want to give their lawns a healthy boost should consider putting their rakes away and mulching their leaves this fall.
