Henbit (Lamium amplexicaule) is a sparsely hairy, winter annual weed with greenish to purplish, tender, square stems. Its opposite leaves are broadly egg shaped with bluntly toothed margins and prominent veins on the underside. Upper leaves are sessile (directly attached to the stem), and lower leaves have petioles.
Henbit grows by roadsides, in cropland, pastures, in waste areas, in gardens, and on lawns. It prefers light, dry soil, and cultivated soil, and it originated in Eurasia and Northern Africa. It also grows in Australia, South America, western Asia, Greenland, and throughout Canada and the United States.

Grow Greens Hydroponically Many golf greens use a hydroponic system for growing grass. This system is installed during construction — a bulldozer makes a hole for the green that is between 12 and 16 inches deep. In more advanced systems, the hole is lined with plastic, before gravel, drainage pipes and sand are added.
The primary solution is preemergence herbicides. Ronstar® is an excellent choice for preemergence control of both crab- grass and goosegrass. Ronstar G or Ronstar impregnated onto fertilizer are both options. Sprayable formulations of Ronstar (Ronstar FLO and Ronstar 50 WSP) CANNOT be used on cool-season turf.
An effective way to get rid of the creeping bentgrass in your lawn is to spray it with an herbicide containing glyphosate. Herbicides such as Roundup with glyphosate are nonselective, so they will also kill the desirable grasses as well as any other plants whose foliage they reach.
