The same traits that make English ivy (Hedera helix) a wonderful ground cover can also make it a pain to remove from your yard. Ivy’s resilience and lush growth make killing English ivy or removing ivy from trees a difficult task, but not an impossible one. If you are wondering how to kill an ivy plant, you will find some help below.

How to Kill English Ivy

There are two ways how to kill English ivy. The first is with herbicides and the second is through manual labor.

Killing English Ivy with Herbicides

One of the reasons that killing English ivy is difficult is because the leaves of the plant are covered with a waxy substance that helps prevent herbicides from penetrating into the plant. So, in order to be effective at killing English ivy, you have to get through that barrier.

The first thing you can do to make herbicide more effective for removing ivy is to use it in the winter on a sunny day. The cool temperatures make sure that they spray does not evaporate quickly and gives the herbicide more time to penetrate into the plant. The sun helps keep the wax on the leaves more pliable and more easily penetrated.

The other thing you can do to make herbicide more effective in killing ivy is to lacerate or cut the plants’ stems. Using a weed whacker or other device on the plant that will damage the stems and then applying the herbicide will help the chemical penetrate into the plants through the wounds.

Removing English Ivy with Manual Labor

Digging and pulling up the English ivy plants can also be an effective way to remove ivy plants from your garden. When removing English ivy manually, you will want to make sure that you remove as much of the plant, both stems and roots, as possible as it can regrow from stem and root pieces left in the ground.

You can make digging and pulling the ivy out more effective by following the directions for applying herbicides after you remove the ivy by hand as best as possible.

Removing Ivy from Trees

A particularly tricky thing to do is to remove ivy from trees. Many people wonder will ivy damage trees? The answer is yes, eventually. Ivy damages the bark as it climbs and will eventually overtake even a mature tree. It is best to always remove the ivy from the tree and keep it away from the trunk of the tree be at least 3-4 feet to prevent it from climbing up the tree again.

When removing ivy from trees, do not simply rip the ivy off the tree. The roots will be firmly hooked into the bark and pulling the plant off will also remove some of the bark and damage the tree.

Instead, starting at the base of the tree, cut an inch or two section out of the ivy stem and remove it. Carefully paint the cuts on the still attached stem with full strength Round-Up. Repeat the process every few feet up the stem of the ivy as high as you can reach. You may need to repeat this a few times before you fully kill the English ivy. Once the ivy has died, you can then take the stems off the tree as the roots will break away rather than cling to the tree.
