Two things to do to keep your lawn looking good this summer: mow more often and water less often. First, set your mower as high as it will go and leave it there for the rest of the growing season. Next, mow your lawn more frequently. Follow the rule of thirds, that is mow often enough you that you take off about 1/3rd of the grass blade per mowing. Keep your mower blade sharp and don’t mow when the grass is wet. You want as clean a cut as possible and wet grass and dull lawn mower blades tear and pull the grass rather than cutting it. Change your mowing pattern every 2 weeks, so you don’t wear patterns into the lawn by mowing the same way every time.
