Growth Requirements: Like most grasses, Barley needs little management once it becomes established in a field. Many species of Barley are aggressive weeds and can quickly dominate certain sites. Occasional mowing, burning, or discing may be required to maintain the field in an early stage of succes­sion where this plant will thrive. This plant is found most often on disturbed fields at less than 6500 feet in elevation.
