Will Roundup Kill Honeysuckle?

Manufactured by the Scotts Miracle-Gro Company, Roundup is a strong chemical herbicide designed to kill unwanted plants and weeds. The product is suitable for a large number of plants and will kill honeysuckle.


Cut the honeysuckle down to a smaller form, cutting down either to the roots or the stump, depending on the type of honeysuckle. Mix the Roundup in equal parts with cold water and apply the mixture directly to the honeysuckle. You may need to apply the solution multiple times to completely kill the honeysuckle.


The Missouri Department of Conservation claims that a solution of just 20 per cent Roundup and 80 per cent water is sufficient to kill honeysuckle. Roundup recommends using at least 50 per cent Roundup and up to 100 per cent Roundup.

Time Frame

Apply the Roundup in the late summer or early fall, when the honeysuckle is most susceptible to the chemicals. Repeat the application within a few days or up to a week after the initial application.
