Grass cutting is one of the most important and labor intensive practices required of lawn care. Cutting the grass is neccessary not just for aesthetic reasons, but also because it keeps the lawn healthy, dense, and weed and disease free. Proper mowing with a sharp lawn mower blade and correct mowing height will keep your lawn picture perfect.
Mowing height varied between different grass varieties. While some grass types require a short height during the summer, some will burn if trimmed to close to the soil. It is important to know the grass type in your lawn and mow accordingly. Mowing height should be selected and maintained throughout the entire mowing season to increase grass density and control weeds. Turf grass blends generally require a mowing height of 3 to 4 inches.
Mowing creates grass clipping which generally rest on the lawn after mowing if not caught in a landscaping bag by the mower. These grass clipping dry in the sun and die, creating a layer over the soil called thatch. Thin thatch is not a problem, but excessive amounts (thicker than one half inch) may begin to decay. Decay from grass clippings causes the conditions for fungal infection and other grass diseases. Rake the lawn if your mower does not include a mulching bag.
The lawn should be cut on a frequent basis to maintain height and increase growth. Cuts should be made according to the one-third growth rule. Mowing should remove no more than one third of the leaf growth to prevent stressing the grass and prevent burning from trapped moisture drying in the sun. During the spring mowing every five to six days should be enough. During the summer, observation is the best method of determining when a cut is required.
