What is a common weed control method used in lawns?

Herbicide application or mechanical removal is a widely recognized and effective method for controlling weeds in lawns. Herbicides are chemicals specifically formulated to target and eliminate unwanted plants without harming the grass or other desired plants when used correctly. There are two main types of herbicides: pre-emergent, which prevent weed seeds from germinating, and post-emergent, which are used to kill established weeds.

On the other hand, mechanical removal involves physically pulling out or cutting down weeds, which can be effective for smaller infestations or individual plants. This method not only removes the visible weeds but can also help in managing their root systems, preventing regrowth.

While mechanical removal and soil aeration, watering techniques, and fertilizing are valuable practices for maintaining a healthy lawn, they do not specifically target weed control in the way that herbicide applications do. Aeration and watering focus on improving overall plant health, and fertilizing is aimed at promoting growth of desired plants, which doesn’t address the weed problem directly. Therefore, using herbicides or mechanical removal is the most focused and effective approach for controlling weeds within a lawn setup.
