What type of herbicides can be used for a fresh start before planting a new lawn?

Nonselective herbicides are designed to kill all types of plants, making them appropriate for clearing an area before establishing a new lawn. Using these herbicides allows for the effective eradication of existing vegetation, including weeds and unwanted plants, thereby providing a clean slate for the new grass to grow.

In contrast, pre-emergent herbicides are typically utilized to prevent weed seeds from germinating, making them more suited for a lawn that is already established rather than for preparing a site for new lawn installation. Selective herbicides are meant to target specific types of weeds without damaging desirable plants, which would not be effective when the goal is to clear the entire area. Systemic herbicides move through the plant's vascular system and can take time to show effects, but their application is typically for managing existing plants rather than preparing a new site.
