Proper lawn management increases weed control success! Proper lawn cutting heights are important when it comes to weed prevention. Lawn scalping refers to cutting your lawn grass to low, so low that you expose the stems of your grass blades. I advise against scalping your lawn due to its damaging effects on the health of your lawn. One problem is that grass blades photosynthesize to provide food to the roots. By chopping off the majority of this blade, you reduce the amount of energy the roots receive, and this makes for a weak lawn that is more susceptible to stress, insects and disease. Another problem with scalping is it encourages weed growth. Without the dense grass blades to block light, weed seeds are allowed to germinate and grow. In a scalped lawn, weeds can quickly dominate. Also, although not a problem in mild areas, the exposed stems of scalped lawns can be damaged by a sudden spring frost. We at T&N Lawn Care take weed control very seriously so you don't have to.
