If you are bagging lawn clippings, you are wasting a valuable resource. Grass clipping left on the lawn provides organic matter to the soil, reducing the need for commercial fertilizer. Never cut more than one-third of the grass height at one time. Mow as needed, and when grass is dry. Keep mower blades sharp.
Cull blades rip and tear grass, which can cause turf disease.
Avoid over-fertilizing your lawn. It encourages overgrowth, which contributes to thatch buildup. The best time to fertilize is in the fall. Water only during extended dry spells. One inch of water every five to seven days is recommended.
