Check your sprinklers often for plugged and damaged heads and fix as needed. Also, water early to avoid the winds from distorting the sprinkler patterns. It may surprise you that mowing too short thins out the turf and causes shallower rooting. That leaves the grass susceptible to drought, diseases and weed invasion. Keep the blades sharp.
Dull blades leave ragged grass blades, making the lawn ugly.
Sharpen blades at least yearly and ideally, monthly. Examine blades if you hit a rock or sprinkler. Mow in opposite directions each time. This keeps grass upright and avoids soil compaction. Never cut wet grass.
