Short grass needs mowing more often

The reason most people mow their grass very short (a practice that's discouraged by all professionals) is that they think they won't have to mow it again as quickly as if they cut it higher. Actually, the opposite is true. Grass clipped very short grows faster because it has to replace its leaves, which provide its food. So do your grass and yourself a favor and mow at 2 to 3-1/2 inches high.
