Applications to foliage can be spot-applied with a hydraulic sprayer with a handgun, mounted on an ATV, tractor, or truck or a backpack sprayer.
Herbicides can be applied to rose foliage or to the stems. Top growth of smaller plants can be removed with conventional mowing equipment. Mowing alone will not control multiflora rose, but it is a great way to make it easier to treat the plant with herbicides. Brush mowers, or similar equipment can be used to cut and pulverize the top growth of established plants. Vigorous, competitive vegetation greatly aids control as well. Controlling rose as small, scattered plants is much easier than trying to eliminate established thickets. Like other invasive species, a combination of control tactics is necessary to manage this plant.įinding multiflora rose early is the best way to simplify control. These seeds can remain viable in the soil up to 20 years.Ī single-method control approach will not eradicate a multiflora rose infestation. Peak bloom is in early June.īirds and browsing animals eat the fleshy, bright red hips and the seeds pass through their digestive systems intact.

Multiflora rose breaks bud early in the spring, quickly developing a full canopy of compound leaves that have seven to nine leaflets. If near trees, the rose behaves almost like a vine, and can grow 20 feet into the tree. When the tips of the stems touch the ground, they can take root (called layering) and form a new crown. When they grow singly, multiflora rose plants have a mounded form because of their arching stems (Figure 2). Individual plants can easily grow to more than 10 feet tall and 10 feet wide. Memorial rose (Rosa wichuraiana) is the only other species with a fringed leaf base, but its flowers are borne singly. Multiflora rose is readily distinguished from other roses by two features - its white-to-pinkish, five-petaled flowers occur in branched clusters, and the base of the leaf where it attaches to the thorny stem is fringed. There are least 13 species of rose that that grow ‘wild’ in Pennsylvania, and most of them are desirable in a wildlife habitat planting. Multiflora rose is very aggressive, and crowds planted grasses, forbs, and trees established on acres to enhance wildlife habitat. Multiflora rose does provide cover and some food value with its fleshy fruit (called ‘hips’), but its overall effect on habitat value is negative. This plant was introduced from Asia and widely promoted as a ‘living fence’ to provide erosion control and as a food and cover source for wildlife. It has the distinction of being among the first plants to be named to Pennsylvania’s Noxious Weed List. Multiflora rose (Rosa multiflora) is an invasive shrub that can develop into impenetrable, thorny thickets.

The following information is derived from a USDA fact sheet and should help landowners understand how to control and eliminate Multiflora Rose. This is especially important to participants whom are required to control noxious weeds on contract acres.
Recently, the Farm Service Agency has been receiving inquires on how to control Multiflora Rose.
Originally introduced as a living fence for wildlife habitat, this weed soon became the state’s No. Multiflora Rose is a problem on many farms throughout Pennsylvania.
