Mowing grass too short can create severe stress on the lawn, causing it to burn out, while creating an environment favorable for weeds to move in. Cut grass too tall, and it will look lain-over and unsightly. Most turf should be mowed at a height of 3.5” to 4” tall. Additionally, it’s crucial to mow the lawn as frequently as needed typically every 7-10 days. And remember, it’s never healthy for the turf if you cut more than 1/3 of the grass height at a time. Keep your lawn mower blade sharp; a good rule of thumb is to sharpen your blades every 3 months if your lawn is ½ acre or less in size. Mowing with dull blades will rip the grass blades making them susceptible to disease and insect feeding.
