What effect does short mowing have on turfgrass root systems?

Short mowing negatively impacts turfgrass root systems by leading to shallow root development. When grass is consistently cut at a lower height, the plant experiences stress, which can trigger a response that limits root growth. The energy and resources that would typically support root development are instead diverted to producing new leaf growth, leading to a shallower root system. This makes the turf more susceptible to drought, disease, and other stresses since the roots do not reach deeper soil layers where moisture and nutrients are available.

This understanding is critical for effective turf management, as it highlights the importance of appropriate mowing heights to maintain healthy and resilient turfgrass. Adjusting mowing practices to encourage deeper root systems can significantly improve the overall health and performance of turfgrass.
