Which management practice is recommended to control thatch accumulation?

The recommended management practice to control thatch accumulation is aeration and dethatching. Thatch is a layer of dead grass, roots, and organic matter that can build up on the soil surface, potentially leading to issues such as reduced water and nutrient absorption, increased disease susceptibility, and poor overall lawn health.

Aeration involves perforating the soil with holes to allow air, water, and nutrients to penetrate down to the root zone. This process helps to alleviate compacted soil and encourages biological activity, which can naturally break down thatch. Dethatching specifically targets the buildup of thatch itself, using specialized equipment to remove the excess layer. By combining both practices, the management of thatch accumulation is effectively achieved, promoting a healthier lawn.

While regular fertilization, frequent watering, and the use of pesticides are important components of lawn care, they do not directly address the underlying issue of thatch buildup. Fertilization might contribute to growth but can sometimes worsen thatch if the grass grows too vigorously without proper management. Frequent watering is essential for maintaining grass health but doesn’t influence thatch directly. Pesticides can help control specific pests but do not have an effect on thatch removal or management. Thus, aeration and dethatching are the
