Which approach is appropriate when weeds are in newly established turfgrass areas?

Using mechanical or cultural techniques rather than herbicides is the most appropriate approach when dealing with weeds in newly established turfgrass areas. Newly established turf is still developing its root system and overall resilience, making it sensitive to chemical treatments that could harm the young grass or disrupt its establishment.

Mechanical techniques can include practices such as mowing, hand-pulling, or using a dethatcher to remove weeds without damaging the turf. Cultural practices may involve improving the health of the turf through proper watering, aeration, and fertilization to promote strong grass growth, which can naturally outcompete emerging weeds.

This approach minimizes potential negative impacts on the new turf while effectively managing weed populations. In contrast, the other options would pose risks to the turfgrass's establishment and could lead to longer-term issues with the health of the turf.
