Lawn Mowing

Home / Tips and Resources / Lawn Mowing

Proper lawn mowing involves the interaction of the height and frequency of mowing.

Most lawns should be mowed no lower than 1 1/2 inches and up to 3 inches. Shaded lawns need the taller mowing height. The personal preferences of the homeowner usually determine the exact height selected.

The lawn should be mowed often enough so that no more than 1/3 of the leaf area is removed at one time. For example, a lawn mowed at 1 1/2 inches should be mowed when the clippings will be less than 1/2 inch long.

It is not necessary to remove the clippings at each mowing. Clippings do not contribute to thatch development. Collect the clippings from diseased lawns to help prevent the spread of the disease. Also collect excessively long clippings to prevent them from piling up and shading spots of grass.

Dull mower blades shred the grass blades rather than cut them. The shredded ends dry out giving the lawn a brownish cast.

Dead grass appearing in the tire tracks from riding lawn mowers can be a hot weather problem. These occur when the lawn was mowed during a time when it was dry. The injury is most evident where the mower turned corners or on slopes. The lawn will recover once it starts growing again.
