Field bindweed is a summer perennial member of the morningglory 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.
Its flowers are white to pink funnel shaped approximately one-inch across. Field bindweed spreads by either seed or rhizomes. Field bindweed is found throughout the United States, generally in rich and sandy or gravelly soils. It is tends to be more of a problem in the Western states.
Field bindweed is very difficult to control due to its extensive root system. In turf situations where cultivation is not practical, a post-emergence 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.
Field bindweed control is best achieved when plants are actively growing and in the seedling to flower stage of growth. Multiple applications may be required for complete eradication.
