Well kept lawns that are mowed weekly only need a small percentage of the grass blade tip to be cut off. Commercial mowers with sharp blades do a great job of cutting the grass into small pieces. Mowing in this manner allows the clippings to be dropped into the lawn without a build up of thatch. If grass is allowed to grow too long, bagging might be necessary. Large lawn care companies might have an over abundance of grass clippings to deal with. A compost heap is the choice of disposal of most professional lawn care operators (LCOs). Care must be taken in choosing the right spot for a compost heap. I look to place my compost heap away from my own lawn. Some customers don't take very good care of their lawn and noxious weeds are in the clippings. I don't want the weed seeds falling into my own yard making it look bad. Also, the compost will probably contain fertilizers. I do not want those fertilizers leaching into the ground near garden vegetables or ornamental plants or trees. Finally, I do not want runoff from the compost to find its way into a small creek that is on my property. So, these are just a few things to consider when doing away with grass clippings. I have been in the lawn care business since the early 1990's. If you are interested in learning more tips, check out my website: http://www.Summer101.com

Most professional Lawn Servicing companies mulch it. If ever they do bag up the cut grass they have what they call a dump site that they use for that purpose.
