Choose the Right Setting, Time and Pattern
Grass does better if it’s cut at a higher mower setting. This also helps cut down on weeds. The optimum goal is to cut one-third of the length of grass, allowing clippings to decompose and return nutrients back into the soil. If the lawn is out of control, mow it at a higher level and then lower the blade and mow again a couple of days later. Higher mowing heights for grass provides for a deeper root system, a better looking lawn and less invasion by weeds.
Avoid mowing in the heat of the day, which can damage the grass, or when the grass is wet, which can damage your mower and leave unsightly clumps. Mowing in varying patterns helps prevent soil compaction and keeps grass healthier. If you want the striped look of a golf course, just put a roller on the mower. You can get a roller at many hardware or supply stores.
