Can cutting height improve a turf’s root system?
Research indicates that taller grass usually indicates a deeper root system. Closely mown grass tends to have a shallow root system making plants more susceptible to hot dry weather. As soon as possible, each spring, mow your lawn short, 1 – 1 ¼ “. This is the 1st mowing it’s ok to scalp your lawn. It cleans it up, gets photosynthesis going, and may help discourage disease. After that though, 2-1/2″ to 3” is ideal. Keeping your turf longer especially during warmer temperatures helps with the color, water conservation, and if you mulch, even better.
