Leave the clippings. The grass biodegrades, adding nutrients and organic matter to the soil. This reduces the need for fertilizer or disposal of clippings. Mulching mowers cut grass into tiny pieces, which quickly break down.
Mow at proper heights. Most lawns should be cut taller than you might think. Taller grass means deeper roots and a more resilient lawn. Since proper grass heights can vary depending on your location, contact your county extension office for regional mowing height recommendations based on your turf type.
water effectively. Watering deeply and infrequently allows lawns to partially dry out between watering. New tech, such as rain shutoffs, moisture sensors and smart controllers can further save time, water and money.
Fertilize properly. Feeding too early or too late weakens lawns and often makes them more susceptible to diseases. Overfeeding promotes insects and disease, and can cause pollution of local waters. Under-fertilizing can result in a lousy-looking lawn and more weeds.
