There are virtually no effective predators feeding on or killing this plant. (1) High seed production and good seed viability. The mechanical control of cutting or mowing is also very effective during these months for the same reason. Not only does the fragrance of multiflora rose waft on the air, but those mites do, too. It’s the law. 4. Allowing the stump to re-sprout during the summer months draws carbohydrate and other growth compounds from the roots and depletes some of the root energy making herbicide kill more effective.

Stems contain thorns and the petioles have … He is a horticulturist at The Country Club, Brookline, MA where he continues his battle with exotic invasive plant species. Foliar application enters the leaves more easily during humid weather because the leaf cuticle / wax layer is thinner making the leaf more absorbent to the foliar – applied herbicide (Ware, 1996). ), then you can dig out the plant or pull it out with a Weed Wrench®. In the 1930’s, multiflora rose was promoted by the United States Soil Conservation Service for use in erosion control and could be used as fencing for livestock.

Educating others (e.g. Cultural Controls: Monitor or visually inspect your property for multiflora rose. (2) Vectors. Pulling, grubbing or removing individual plants from the soil can only be effective when all roots are removed or when plants that develop subsequently from severed roots are destroyed. 3. Leaves emerge very early in the spring, earlier than most native plants, and this species holds onto its leaves a little longer in the fall than most native plants. Description: Wild roses have been used by people for centuries, provide food for pollinators, birds and mammals and are even the provincial flower of Alberta. Therefore, wind transport is minimal (Evans, 1983). A combination of these methods of reproduction can allow populations of multiflora rose get quickly out of control. It has escaped cultivation spreading into private and public lands, and as a result has been classified as a noxious weed in many states (Dryer, 1996; Symonds, 1963; Munger, 2002).
