Get the Mowing Height Right for the Right Time of Year. There’s more to mowing than just cutting the grass every Saturday. One of the most fundamental steps to a perfect lawn is getting the mowing height right for your type of lawn and for the season. Most grasses do best with a length of 2 – 3″. This applies for spring and early fall. In the summer, if possible, set it even higher.
Never go below the minimum recommended height except for the last mowing of the season which should be around 1.5″ for most turf grasses. Height is important because the grass uses the extra length to absorb the sunshine it needs to grow and develop into a healthy plant. Never remove more than 1/3 at any one mowing. This may mean you’ll have to mow more often during prime growing times (usually spring and early fall). Leave the clippings on the lawn after you mow. This not only save time and energy, but the clippings decompose and add vital nutrients back into the soil.
