Why is grading necessary before planting turf grass?

Grading before planting turf grass is essential primarily to ensure proper drainage. Proper grading creates a slope that directs excess water away from the area where the turf will be established, which helps to prevent water pooling and minimizes the risk of diseases associated with overly wet conditions. When water drains appropriately, it also contributes to healthier root development, as the roots need air as well as moisture. Adequate drainage can improve the overall vigor and resilience of the turf grass, enabling it to withstand drought and stress better. Ensuring proper drainage is a fundamental practice in successful turf management and establishment.

While aesthetics, soil pH, and soil fertility are important considerations in establishing a healthy lawn, they are secondary to the critical role that proper drainage plays in the overall establishment and health of the turf.
