Your grass can literally be smothered by densely packed autumn leaves! For the health of your lawn, it is important to rake or blow the leaves off the grass.
Fall leaves are "gold" to gardeners because they provide a fantastic source of "free" organic nutrients for your lawn and gardens.
If you regularly mow your leaf covered lawn before the leaves get too thick, you may never have to rake a single leaf! The mower shreds the leaves into small pieces which will break down quickly in a compost pile. As long as the leaves aren't piled too deeply, a mulching mower makes the job even easier because the chopped leaves are deposited right on the lawn where they will break down over the winter, providing nutrients to the grass and improving soil structure.
Shredded leaves also make a great organic mulch and soil conditioner for your perennial beds and vegetable gardens.
