In respect to this, is it bad to leave leaves on your lawn?

So yes, you can leave the leaves. The leaves will serve as mulch and will protect the soil around your trees, shrubs, or garden. Research done at Michigan State actually shows that leaving the leaves on your yard in such a manner not only does your lawn no harm; it can actually impede weed growth.

Also, should leaves be left on lawn over winter? It Is a Matter of Lawn Health, not Just Tidiness That lawns, too, have to "breathe." The lawn will be smothered in a thick layer of unshredded leaves if left on top of them over the winter. That, if the leaves are matted down, they can even keep new grass blades from emerging next spring.

Simply so, can fallen leaves kill grass?

Unless you have a very heavy layer of leaves, they won't smother your lawn. Most lawns are going dormant by the time leaves start to fall, so the myth that leaves will kill grass is false. Leaves biodegrade, of course, and they'll decompose by the spring.

What happens to grass if leaves are not raked?

However, when so many leaves fall that they form thick clumps or layers, they block out light and air from lawn grass. If the leaves aren't removed, the grass can die, and in the spring the lawn may have bare patches that require reseeding or resodding.
