Why is cutting the grass too short considered dangerous for a grass field?

Cutting the grass too short is indeed considered dangerous for a grass field because it can damage the roots. When grass is mowed at a height that is too low, it can stress the plant because the blades are responsible for photosynthesis. When there are not enough blades left, the grass struggles to produce the energy it needs to thrive. This reduced energy can weaken the lawn’s root structure, making it more susceptible to diseases, pests, and environmental stresses. Additionally, shorter grass may not provide sufficient shade to the soil, leading to increased soil temperatures which can further damage the root system.

Maintaining the appropriate grass height ensures that the grass can remain healthy and resilient, supporting both the aesthetic quality of the field and its functional performance for sports and recreational activities.
