Do you trim your lawn to a nice short length or keep the grass blades a bit longer?
Have to agree with you and some others here 100% on this one. I mow my lawn with a walk behind mower set at the highest setting. Since I've started this practice (several years ago now) my lawn's been much better off for doing so. At first the mower would lay the grass over when cutting it since the grass was so long but over time and by alternating the direction in which I mow each time the lawn grass has done very well thus far.I have my lawn tractor set at 4", helps promote deep roots, and the taller grass shades young weeds, making it harder for them to grow.
