Which method helps maintain a healthy turf during cold seasons?

Maintaining a healthy turf during cold seasons is critical for the overall health and recovery of the grass. Overseeding, which involves sowing grass seed over existing turf, is particularly beneficial because it helps to fill in thin areas and introduces more resilient grass varieties that can better withstand cold temperatures. This process enhances turf density, reduces weed competition, and promotes a robust root system, which is crucial for the grass to survive harsh winter conditions.

By using overseeding, you ensure that even if some of the grass goes dormant or dies due to cold weather, other areas remain healthy and vibrant. Additionally, overseeding can also provide better color and texture to the turf as spring approaches, resulting in a quicker recovery and a more appealing playing surface when temperatures rise again.

The other methods, while important in their own contexts, do not specifically enhance the turf's resilience during cold seasons to the same degree as overseeding. For example, reducing watering is essential for preventing root rot in wet conditions but can lead to drought stress if not managed properly. Topdressing helps improve soil structure, but may not address the immediate needs of the turf during the winter effectively. Infrequent mowing can help reduce stress on the grass, but it does not actively promote the health of the
