Control options for roughleaf dogwood and smooth sumac

Two common brush species native to Kansas and widely spread across the state are roughleaf dogwood and smooth sumac. These shrubs can produce clumps that will shade out and reduce forage production. Be on the lookout for these shrubs and implement a control plan if needed.
