What height is generally suggested for optimal mowing?

The suggestion of mowing at a height of 1.5 times the normal height is rooted in agronomic principles that promote turf health and resilience. Mowing at this height allows for better photosynthesis because the grass blades can capture sufficient sunlight, which is essential for growth. Taller grass also has a deeper root system, which improves drought resistance and encourages denser turf, reducing the establishment of weeds.

Additionally, maintaining grass at this suggested height can help protect it from stresses caused by heat and disease, as the extra height helps to shield the soil and root system from extreme temperatures. Furthermore, a taller grass canopy allows for enhanced soil moisture retention, which is beneficial in maintaining healthy turf.

Other height options, while they may have their own merits in particular situations, do not align as well with the overall goal of optimizing grass health and providing the necessary support for vigorous growth.
