Uses in Traditional and Modern Eras

Value for wildlife: The fruits are enjoyed by birds which further aid in its spread.

Utility for Humans: NONE – INVASIVE — Amur honeysuckle is highly adaptable, forming dense stands that crowd and shade out native plants, greatly reducing biodiversity.  It is shade tolerant, and resistant to heat, drought, and severe winter cold. 

Homeowner’s Corner: Do not plant invasive honeysuckle species as ornamental plants. Eradicate existing plants on your property. There are native species which can be planted as alternatives, you can find a list of them in the MIPN Landscape Alternatives brochure.

Foliar, stem injection, and cut-stem application of herbicides that translocate their active ingredients into the root system can be very effective. Treatments will need to be repeated for several years to eradicate a population. If using herbicide treatments, check with your local University of Minnesota Extension agent, co-op, or certified landscape care expert for assistance and recommendations. There are several businesses throughout the state with certified herbicide applicators that can be hired to perform chemical applications.

Young plants can be pulled by hand. Mature plants can be removed by using a weed wrench tool or by repeated cutting. Keep in mind that physical removal in this manner can disturb soils and result in reinvasion or re-sprouting of honeysuckles and other exotics. Prescribed burning can be an effective tool to control infestations in combination with other techniques. Spring burning will kill seedlings and the tops of mature plants. Make sure to contact the Minnesota Department of Natural Resources to learn more about control burning practices and regulations.
