Selecting the Right Mowing Height for Your Grass

All grass varieties should be mowed at or near their optimal mowing height. This will keep grass healthy and dense (highest number of shoots per unit area). Higher density means more soil surface shading, which severely restricts the germination of many annual grassy and broadleaf weeds. Maintaining a dense and healthy lawn is the best weed control.
