Which practice can be effective in reducing weed seed germination?

Maintaining a thick and healthy turf cover is an effective practice for reducing weed seed germination because a dense turf can outcompete weeds for light, water, and nutrients. When the turf is healthy and robust, it creates an environment that is less conducive to weed establishment. The grass plants themselves can shade the soil, thereby inhibiting sunlight exposure to weed seeds that might otherwise germinate. Moreover, a thick turf layer can help retain soil moisture and create a competitive environment that deters weed growth.

In contrast, practices like frequent deep tilling can disturb the soil and potentially bring dormant weed seeds to the surface, which may encourage germination. Watering after herbicide application focuses on aiding the effectiveness of the chemical, but it does not directly contribute to reducing the potential for weed seed germination. Relying solely on chemical controls lacks the long-term sustainability and ecological balance that a healthy turf management strategy would promote, making it less effective in providing lasting weed suppression.
