Many wonder how high or how short should they mow their lawn? It's a good general rule to mow high. How high? 3" - 3 1/2" is good for most of the season. At the very end of the season you can lower the height of the lawn mower really short. How short? Well short enough but don't scalp the grass. We don't want any tall grass left when the snow comes. If the grass is tall when winter comes then it will get moldy underneath the snow.
When the lawn is mowed high it will actually shade the soil and allow any moisture in the soil to be used by the grass and prevent some evaporation. Also it will help prevent some of the weed seeds that are blowing in the wind from working their way down into the soil... this means less weeds : )
If the lawn is mowed too short then the soil will dry out faster, get more weeds and won't be healthy, thick and beautiful despite any lawn applications done to it.
