Use the height of your grass to determine how often it needs to be mowed. For most lawns, the optimal height is between two and three inches. To keep you lawn looking its best, cut only one-third of the leaf blade each time you mow.
Change directions each time you mow. This will keep the grass growing upright instead of leaning in the direction you mow. Changing directions will also reduce turf wear and the possibility of scalping.
Keep your mower blade sharp. A dull blade shreds and rips grass instead of cutting it cleanly. Brown leaf tips, certain diseases, and insects are several of the problems associated with grass cut by a dull blade. A good rule of thumb is to sharpen your blade once a month.
