Grass clippings can recycle valuable nutrients into the lawn. Clippings are about 70 percent water and decompose quickly.

Grass clippings do not cause thatch to form in lawns if the lawn is mowed properly. Lawns should be two to three inches tall after mowing. Mow often so no more than an inch of grass is removed during each mowing.

In grassSpecial recycling or mulching mowers chop grass clippings into smaller pieces so that they sift down into the lawn more quickly. These mowers work best when the lawn is mowed at least two times a week in the spring.

Grass clippings should be removed anytime large clumps of clippings remain on the lawn. If large clumps of grass are forming when a lawn is mowed, it is because the lawn is not being mowed frequently enough or it is mowed while very wet from dew or watering.
