What is a pre-emergent and a post-emergent?
Rate This FAQ
A pre-emergent herbicide kills plants as they emerge (seeds) from the soil, and a post-emergent works after the plants are growing. There are non-selective herbicides (kill all plant life) and selective herbicides which either kill only broadleaf or only grassy plants. Carefully read instructions on chemical container so herbicide damage will not occur on plants that are near by in the landscape.
