General description

Carpetweed is a summer annual broadleaf weed that spreads by seed. Seeds begin to germinate as soils begin to warm in early spring and continue to germinate throughout the growing season. The weed is low-growing and forms a circular mat of growth. Produces small white flowers at the leaf axils in mid-to-late summer. Has smooth leaves that are light green in color.

Management in lawns

Cultural lawn care practices

  • Maintain healthy, dense turf that can compete and prevent weed establishment.

Mechanical Management

  • Hand pulling or using an appropriate weeding tool are the primary means of mechanical weed control in lawns. This is a viable option at the beginning of an infestation and on young weeds. Hand pulling when the soil is moist makes the task easier. Weeds with tap roots like dandelions or have a basal rosette (leaves clustered close to the ground) like plantain are easier to pull than weeds such as Bermudagrass (wiregrass) or creeping Charlie (ground ivy) that spread with stolons or creeping stems that root along the ground.

Chemical Treatment in Lawns

*Do not spray herbicides containing dicamba over the root zone of trees and shrubs. Roots can absorb the product possibly causing plant damage. Refer to the product label for precautions.
