Field bindweed is a summer perennial member of the morning glory family. The leaves of field bindweed are arrowhead shaped and appear alternately on long creeping stems. Field bindweed has an extensive root system which may extend up to 15 feet underground.
Field bindweed is very difficult to control due to its extensive root system. In turf situations where cultivation is not practical, a postemergent herbicide is generally recommended. Small infestations of bindweed in non-turf areas may sometimes be controlled by covering with mulch and not allowing any green plant material to emerge.
