Just be sure you never cut off more than a third of the grass blades at any one time, even if you have to cut weekly, or more. Drop those clippings. Leave the grass clippings where they fall. They provide half of your lawn's nitrogen needs. And they add organic matter to your soil, which keeps important beneficial microbes in the soil active and well-nourished.
Many people fertilize their lawn too much, too often.
That makes the grass susceptible to disease. And it makes the lawn grow faster, so you have to mow more often. Most lawn grasses require 3 to 4 pounds of nitrogen per 1,000 square feet annually. Grass clippings left on the lawn return about 2 pounds of nitrogen to the soil. Spread a quarter-inch layer of compost on the lawn and you add another pound.
