By now, your lawn growth will have started to slow. Slower growth means slower recovery and repair when damage occurs. It also means less resistance to stress from insects, diseases and heat. On the other side of this brochure, we’ve recommended a cutting height of 4 inches. Proper cutting is the single, most important key to maintaining a healthy lawn. Mowing right helps the lawn to thicken up, increase in density, thrive while other lawns are suffering, reduces the need for watering, and increases stress resistance. Mowing incorrectly, even once, stops all of this from happening. Poor mowing practices don’t simply stress the lawn, it actually damages it. There is a difference. On the front of our lawn sign that you’ve been keeping near your front steps, is a handy ruler for your convenience whenever you cut your lawn.
