Take a look at your grass blades after a recent mowing. Roughly-cut or brown edges indicate a problem. Jagged edges generally mean that your mower blades are too dull. You can have them sharpened at our shop or get new ones, if need be. If your mower blades are properly maintained but the tips of your grass are brown, it may be that you’ve been cutting the grass too short.
As a general rule, you should set your mower height so that you cut off no more than 1/3 of the grass blade length at a time. And, a higher grass height will guard against your mower blades scraping hidden rocks.
Taking off more than 1/3 is called scalping. Scalping can sunburn your grass by suddenly exposing shaded areas to the light. If you’ve missed a few mowings and the yard looks a little like a jungle, it can be very tempting to just cut it all down. Don’t.
So how tall should your grass be?As a general rule, grass should be shorter in cool weather and longer in hot weather. Short grass (1 ¼“ to 2”) in the spring allows excess rain to run off instead of pooling; long grass (3” to 4”) in the summer offers shade and moisture retention; short grass (1 ¼“ to 2”) in the winter prevents grass from matting under snow and so helps prevent fungi problems in the spring.
When you mow, the grass is bent over in the direction that the mower is moving. If you mow in the same direction every time you cut the grass, the grass will be less and less likely to spring back up, and you will probably also develop wheel ruts in the your lawn. So, if you want a lush, springy lawn, alternating the direction you mow every time will prevent bent grass. However, if you like patterned lawns, use bent grass to your advantage. Keep in mind that some types of grass are more suited to
pattern mowing than others.
