How to control multiflora roses?
A combination of methods works well for controlling multiflora rose. Individual plants can be dug up or controlled with herbicide. The cut stump method is one way to target the multiflora rose with less risk of harming other plants. Larger patches of plants or dense thickets can be controlled by frequent, repeated cutting or mowing at the rate of three to six times per growing season, for two to four years. Another method is to cut the plants and then spray the re-growth with a systemic herbicide such as glyphosate or triclopyr. Glyphosate works better late in the growing season. No biological controls are available at this time. No matter what method is chosen, follow up is essential because of the long-lived seed bank in the soil.

For the last decade, Rosa Flora has ramped up its investment in Integrated Pest Management systems, with the use of biological pest controls. That is, we use natural pests to fight the bugs we don’t want in our crops. This requires careful monitoring and control by our trained staff. Where pesticides are used, they are tightly contained and bio-friendly. In fact, we will even use soap or water to spray away pests!
Why is multiflora rose a weed?
Multiflora rose ( Rosa multiflora) was originally introduced into the United States from east Asia in 1866 as rootstock for ornamental roses. It was also planted as a living fence, for erosion control, and to provide food and cover for wildlife. It is listed as a "Class B" noxious weed by the State of Pennsylvania, a designation that restricts sale and acknowledges a widespread infestation. Like other shrubs with attractive flowers, multiflora rose persists in our landscape partly due to citizen unwillingness to remove plants perceived to have aesthetic value or value to pollinators and other wildlife. However, the dense, monocultural thickets created by multiflora rose degrade natural enivronments and reduce native plant and wildlife diversity.
What is the disease on a rose plant?
Biocontrol agents do exist for multiflora rose, but they are generally difficult to apply in a targeted fashion and will often affect related nontarget vegetation of the same genera or family. Rose rosette disease , also called witches-broom, is a mite-vectored viral infection of the growing tips that results in stunted, nonfunctional growth that is often a vibrant red color. While the virus will eventually result in death of the plant, it can take years, making this method unreliable as a form of consistent treatment. The disease also infects other native and exotic species of the rose family, including other roses, cherries, plums, apples, and pears. While two nonnative and naturalized insects, the rose stem girdler beetle (Agrilus cuprescens) and the rose seed chalcid wasp (Megastigmus aculeatus), do kill individual plants, their populations are not robust enough to produce a widespread population reduction. As such, the presence of these controls is more of a positive but chance event than a true treatment.
How to control multiflora roses?
The efficacy of and methods for mechanically controlling multiflora rose depend on the intensity of invasion and age of the population. Small populations of young plants are not difficult to pull, taking care to use protection against the thorns. Be sure to pull the entire root system to prevent resprouting. Similarly, using a brush mower to cut larger infestations will temporarily set back the population and stress the plants, but it will not eliminate them and resprouting will result.
What is the difference between a multiflora rose and a blackberry?
While very similar in appearance to other roses, both native and exotic, multiflora rose is unique in having fringed stipules at the base of the leaf. Native black raspberry ( Rubus occidentalis) and Allegheny blackberry ( Rubus allegheniensis) have thorns, similar growth habits, and a tendency to form thickets, but they usually have red or purplish canes rather than the consistent olive green of multiflora rose. Another invasive cane-forming shrub that could be mistaken for rose is wineberry ( Rubus phoenicolasius ), but its canes are thickly covered in pink hairs rather than prickles.
How long does a multiflora rose seed bank last?
They are prolific seeders and also aggressively expand through layering. Their seed bank can continue to produce new plants for up to 20 years, and fragments of the root system left behind can sprout.
Why is the management calendar for multiflora roses flexible?

Where is Multiflora Rose native to?
General Description: Multiflora rose is an exotic invasive perennial shrub native to China, Japan, and Korea (Zheng et al 2006; Dirr, 1998; Amrine and Stasny, 1993). Introduced into the United States in the 1860s (Dryer, 1996), multiflora rose was used in the horticultural industry as readily available rose root stock for rose breeding programs and as an ornamental garden plant (Amrine and Stasny, 1993). By the 1930s it was widely planted in the Midwest and northeastern states at the encouragement of the USDA, Soil Conservation Service for erosion control programs, wildlife habitat enhancement programs, and as a natural barrier to roaming farm animals (i.e. “living fence”) (Amrine and Stasny, 1993; Evans, 1983).
Why do we use multiflora roses on highways?
Evans (1983) also states that some highway departments encouraged the use of multiflora rose on highway median strips to reduce headlight glare from oncoming traffic and as a natural crash barrier to stop out-of-control cars because of this species’ ability to form dense thickets quickly. As with other exotic invasive plants, ...
What is a rose seed chalcid?
The rose seed chalcid, Megastigmus aculeatus var. nigroflavus Hoffmeyer is a wasp native to Japan, but has become established in the United States as a naturalized beneficial insect. Both males and females exist. Female rose seed chalcids (Hymenoptera: Torymidae) lay eggs in the hips of multiflora rose plants and the developing larvae feed on the seeds disrupting seed maturation and development resulting in substantial seed mortality. However, the spread of this wasp is slow (Munger, 2002). Munger (2002) suggests that in time, the chalcid wasp and Rose Rosette Disease (RRD) will overlap in range as combined bio-control agents working in concert to controlling this pestiferous exotic. RRD is mentioned in Part II, IPM Control Strategies for Exotic Invasive Plants. RRD is a plant virus that causes the canes to undergo “witches broom” and the leaves exhibit a dark colored purple mosaic blotching, resulting in a slow death for multiflora rose (Amrine and Stasny, 1993).
How to control multiflora roses?
2. Mechanical Controls: Pull, dig, mow, and cut. Pull out easy-to-pull plants. If you can’t hand-pull multiflora rose (be careful of the thorns!), then you can dig out the plant or pull it out with a Weed Wrench ®. Spring or early summer cutting of multiflora rose will slow its growth, but may not inhibit flower, fruit, and seed production. Repeated cutting or mowing on a monthly cycle will be more effective at stunting the plant and inhibiting fruit and seed (berry) production. Munger (2002) recommends that for established or old thickets mowing or repeated cutting from three to six times per growing season for two to four years will control the spread of this plant and reduce its existence in the mown area. If you decide to mow established thickets, please be aware that multiflora rose seed has a seed bank of great longevity. As you mow you will be increasing sunlight levels on the ground and contributing to the germination of seed bank seeds. Therefore, you may be controlling this pest for a longer period of time than you had originally anticipated. Mechanical controls can be done at any time during the year; however, the best times are the months before or during flowering.
What tree has green leaves?

What is a rambler rose?
Rambler rose, also known as multiflora rose, is aptly named for its copious sprays of abundant white flowers borne on dense, arching branches. Birds feed on the fruits and disperse its seeds widely -- especially the Northern mockingbird (Mimus polyglottos). First introduced to the United States from Japan in 1886, multiflora rose was widely used as a rootstock for grafting cultivated roses. It was promoted as a highway planting, a living fence, an erosion control agent, and a planting to attract wildlife. Today, multiflora rose is regarded as an invasive species in many portions of its range.
