Henbit

This winter annual weed commonly infests thin or dormant lawn areas. You can identify henbit (Lamium amplexicaule) by its square stems, opposite leaves, and reddish-purple flowers.

Control: Handpulling is a simple, practical approach for small areas. Improve the health and density of the lawn by fertilizing at the right time and with the correct amount; maintaining an appropriate soil pH; mowing at the recommended height; and watering properly. Apply a two- to three-inch layer of mulch to ornamental bed areas to suppress germinating weed seeds. Since this weed reproduces by seed, control it before seeds are produced. Herbicides are available depending on the crop grown.
