Should you leave the leaves? Check out these selections from the Engineering Library to see for yourself

Fall is a beautiful time but very few people enjoy raking all of the beautiful leaves that collect on their lawns. Experts now say that raking every single leaf may not be necessary. When left in place, leaves serve as habitat for several types of wildlife, retain moisture in your yard, and can even help suppress next year’s weeds!

If you have a very thick layer of leaves all over your yard, consider raking most of them and composting the ones that you pick up or moving them to a garden bed to work as a natural mulch. If you have a moderate layer (50% of yard cover), you can run your lawn mower over them to help them break down more easily but otherwise leave them in place. If you have a scattering of leaves on your lawn, you can just “leaf” them alone!
