Groundcover is any plant used for the purpose of growing over an area of ground to hide it or to protect it from erosion or drought.
Strictly speaking, the most widespread groundcover are grasses of various types. In common parlance, however, the term groundcover refers to non-grass plants that are used in place of grasses.
Three general types of plants are commonly used as groundcovers:
The goal of groundcover management is to promote the growth of native plants as a groundcover to protect the soil, promote good tree root growth, and provide a habitat for natural insect and mite predators without hurting tree growth and quality.
Groundcover suppression or "chemical mowing" is a term used to describe the practice of applying postemergent herbicides at low rates to stunt or suppress weeds and grasses.
Be careful not to kill all the groundcover in the fall or else you might expose the soil surface to erosion through the late winter and early spring.
