Summer Lawn Care - Mow It High and Let it Lie

Most lawn grasses will do their best when cut to 3" high. At this height, the plants shade the soil, develop deeper root systems, and reduce weed seed germination. Cut the grass again when it reaches 4"- 5” in height. Keep the mower blade sharp so the grass is cut even and clean, without ragged leaf ends that will turn brown.  Leave the clippings on the lawn rather than bagging them. The clippings are high in both moisture and nitrogen and will break down quickly, acting as a slow-release fertilizer.  For more information on home lawn care visit: https://www.ag.ndsu.edu/horticulture/lawns-1
