Pro Tip: Your grass might be as short as a putting green, but don't keep it that way. Let it grow to a length of about 3 to 3½ inches, and maintain that height all season. This allows the grass blades shade out w**d seeds, and in the summer it shades the soil, reducing evaporation. Come fall, you can go back to cutting it short—w**d seeds aren't as abundant then, and evaporation is less of a concern. Two exceptions are Bermuda and seashore paspalum grasses, found in the South, which can be kept at a height of 3/4 to 1 inch.
