Mowing at the right height keeps grass strong and green. Regular mowing helps water and nutrients reach roots better.
Common Mowing Mistakes To Avoid
Cutting Tall Fescue too shortcan stress the grass. It removes too many leaves at once. This weakens the roots and slows growth. Keep mower blades high, around 3 to 4 inches. Taller grass helps shade the soil and reduce weeds. Short cuts can also cause brown patches quickly.

During summer, tall fescue grows slower. Set mower height to 3.5 to 4 inchesto protect grass from heat and drought. Mowing less often helps the grass stay cool and hold moisture. Water deeply but less often to support roots.
In fall, grass grows again with cooler weather. Lower mower height gradually to about 2.5 to 3 inches. This helps prepare grass for winter and removes dead blades. Fall mowing encourages thick, healthy turf for spring.
