It is important to know that the appropriate range of mowing heights varies with the type of turfgrass. Not all experts agree on the optimum mowing practices for water-conserving landscapes.
However, a common recommendation is to raise the mowing height to the upper end of the range. The longer turfgrass is able to develop a more extensive root system, which is beneficial during dry periods.
Mowing Heights
A mowing height of less than two inches creates a shallow root system that needs moisture more often.
A mowing height of 2 to 3 inches has two advantages.
-
Longer blades wil shade each other and the soil, reducing moisture loss.
-
The root system grows longer and thicker.
