Japanese Honeysuckle

Japanese Honeysuckle

What is it?
Japanese honeysuckle (Lonicera japonica) is recognized as one of the worst exotic invaders in the eastern United States.  

Japanese honeysuckle is a woody vine which can climb or trail up to 40 feet in length. It generally forms dense mats of vine-like, opposite branches with round, slender stems rarely attaining a diameter of two inches. 


How do I control it?

Mowing, cutting, pulling, or burning the aboveground growth does not kill the plant and in many cases stimulates even denser regrowth the following year. Because it is essentially growing year-round in Kentucky, herbicides can be applied to Japanese honeysuckle in the winter without harming other native trees and shrubs in the area; you may even allow native seeds present in the soil to germinate. Bear in mind, to maximize herbicide effectiveness and safety, only apply herbicide on a relative dry, sunny, and windless day with temperatures over 40°F.
