Lawn care pros recommend varying your mowing pattern. That is, you want to push the mower north and south one week and east and west the next week. Sharpen your mower blades a couple of times a year to ensure a healthy, clean cut. (ahas, that's our problem!) If you have a mulching mower, you can leave the clippings on the lawn to help fertilize the grass, or, use them in your compost!
