OSU Extension recommends that you learn to identify Scotch broom and the other non-native broom species in the Pacific Northwest that have the potential to become weedy. "Native trees (such as Douglas-fir or red alder), shrubs (such as woods rose, currants and snowberry) and native grass mixes can help prevent and slow Scotch broom infestations." "Quickly re-vegetate disturbed sites with fast-growing, competitive native plants to limit Scotch broom spread," he said.
Care should be taken not to transport soil that is contaminated with Scotch broom seeds. What can you do to control this noxious weed? Prevention is the best method, especially in areas where the ground and other plants have been disturbed by overgrazing or development, Hulting said. Scotch broom costs Oregonians an estimated $40 million per year in lost timber revenue and control efforts. "Its invasive habit and economic costs have landed Scotch broom on the State Weed Board's list of noxious weeds, along with its relatives French, Portuguese and Spanish brooms and gorse," Hulting said. The woody shrub establishes quickly in disturbed areas, according to Andy Hulting, a weed specialist for the Oregon State University Extension Service. Later it was used to prevent erosion and stabilize banks and sand dunes. Scotch broom was introduced from Europe as a garden ornamental by early settlers of the Pacific Coast. – Although admired for its yellow blooms, the Scotch broom shrub has become an invasive species throughout the Pacific Northwest, where it competes with native plants and forms dense stands that are difficult to manage and remove.
