Lawn Mowing Issues

Lawn mowing requires a properly maintained mower and knowing the frequency and height to cut the grass. The height and density of the top grass is a direct reflection on the depth and density of the root system supporting the top growth. Different grass species require different root system depths for optimum health, which is why lawn mowing and grass height matter more than simple aesthetic appeal.

Frequency

Start mowing the lawn grass in the spring in accordance with the 1/3 rule, which states you should remove no more than 1/3 of the grass blade when mowing. For example, cool season grasses such as fescue, bluegrass and ryegrass prefer a height of approximately 3 inches and should be cut back to that height when reaching 4.5 inches. Use the 1/3 rule through the summer and fall to determine the correct time to mow the lawn.

Height

Each lawn grass species has its own ideal height for optimum health. As a general rule, cool season grasses such as fescue, bluegrass and ryegrass prefer a height of approximately 3 inches; warm season grasses such as Bermuda, zoysia and centipede prefer a closer cut of approximately 1 inch. The ideal height should be maintained in accordance with the 1/3 rule.

Clippings

After mowing the lawn, leave the clippings to promote grass growth. Grass clippings decompose into the top soil, providing a rich source of minerals and nutrients for the soil as well as providing moisture retention and temperature stability. Grass clippings are a form of natural fertilizer that will reduced the need for more traditional fertilizer applications.

Lawn Mower

Make sure your lawn mower is effective and safe by having an annual inspection preformed during the winter months when grass growth is slow or dormant. During the inspection, the mechanic will check fluid levels, gasket fittings and blade sharpness. Sharp blades are better for lawn health, promoting a clean cut as opposed to the ragged, torn grass ends produced by a dull lawn mower blade.
