What should I do with Grass Clippings?
If the lawn is healthy, it is not necessary to remove grass clippings, assuming the grass clippings are able to drop into the lawn. In fact, leaving the clippings has positive benefits because they gradually decompose, feeding the lawn. It is important to note that clippings do not contribute to thatch. If a lawn is maintained very short, or if the clippings sit on top of the grass, remove them to avoid smothering the grass.
