The beauty and sweet scent of honeysuckle blooms makes this fast-growing a vine a delightful addition to the landscape. The vines, which can grow up to 20 feet, need no help climbing fences and trees or creeping over shrubs and the ground. Birds spread the seeds, causing the vine to sprout in undesirable locations. It's this spreading growth pattern that has led to honeysuckle's “invasive” label. Killing invasive honeysuckle can be challenging and takes continued effort to eradicate the vines.
Pull or dig up as much of the vines as you can in the spring. This technique works best when the ground is moist and on young plants whose roots have not spread.
Cut the vines as close to the ground as you can in the summer. Use hand pruners or loppers. In dense situations, a chain saw will work faster.
Apply a commercial herbicide immediately after cutting the vines back. Apply the herbicide according to the manufacturer’s instructions. Wear protective clothing and keep pets and children out of the area until the product dries or according to the herbicide instructions, whichever is longer.
Repeat Steps 2 and 3 in both the fall and winter.
Repeat Step 1 the following spring and restart the cycle of cutting honeysuckle to the ground and immediately applying herbicide in summer, fall and winter until the vine no longer grows. It can take up to 5 years to completely eradicate the vines.
