Roundup is one of the most popular herbicides used for controlling the growth of unwanted plants and trees. English Ivy is a perennial evergreen woody plant and you might wonder if it can be killed using Roundup.

The most effective way to kill small English Ivy with Roundup would be spraying the entire foliage of the tree with Poison Ivy Roundup Mixture during early spring. For taller plants, you have to cut all the vines from chest height and spray the remaining stump with the mentioned herbicide mixture.

Let’s take a look at whether you can use Roundup on English Ivy and how to use the herbicide correctly for the best results.

How Does Roundup Work?

Roundup is designed to be applied to plants by spraying the leaves or the foliage of the tree with it.

The main active ingredient in Roundup is called Glyphosate which is a systemic chemical in nature. This means that the chemical, after being absorbed by the leaves, travels all throughout the tree using its vascular system, all the way to its roots.

Glyphosate then targets and inhibits a specific within the tree called EPSP Synthase. This enzyme is responsible for regulating the production of essential proteins which a plant needs for growth.

Will Roundup Kill English Ivy?

Roundup can be effective on English Ivy if applied correctly. One of the advantages, which also can be a downside, is English Ivy’s ‘vine-like’ stems which can easily be accessed using a portable sprayer.

English Ivy is usually small in size which further increases Roundup’s efficiency on the plant. You can start seeing its effects on the tree within a few hours and they end up dying within a week or two after being treated with the herbicide.

The absorption levels can be low due to the leather-like texture of its leaves which is why it is recommended to use the herbicide during springtime when new leaves are also growing.

How Long Does it Take to See the Effects of Roundup on English Ivy

Roundups’ effects on trees can be seen within a few days after being applied and a small to medium-sized tree will end up dying within a couple of weeks after applying Roundup.

One of the first signs of Roundup being effective can be seen through the color of the leaves. The leaves will turn dark yellow or brown and eventually fall off. The plant will slowly die over the course of a couple of weeks after that.

What Equipment Will You Need to Use Roundup?

One of the reasons for Roundup’s popularity is its ease of use. You don’t need to mix it with anything to dilute the chemical and it can be used straight out of the container.

Other than Roundup, you will need an effective delivery method. A backpack sprayer or a portable sprayer should be able to get the job done.

If you only have to kill a few shrubs you should use a comfort wand that comes with the Roundup. It is a small, portable spraying device that will give you a continuous herbicide spray without any extra equipment.

If the English Ivy is growing up other trees, high fences, or walls you will also need an ax, hatchet or a saw to cut the vines.

How to Use Roundup Correctly?

Fill the sprayer with Roundup and you are good to go.

The most effective way to apply Roundup would be to spray the entire foliage and cover all leaves of the English Ivy.

Make sure that the leaves are dry and there is little to no wind during this process as the herbicide will get carried away.

If you are working on English Ivy that is tall and not reachable by the sprayer you have to cut through the vines at chest height and spray the remaining stumps and leaves.

The other option is to cut all the vines from the base and spray all sprouting leaves or saplings later down the line.

What’s the Best Time of the Year to Use Roundup?

The best time to use Roundup on English Ivy is during early spring when new leaves are being formed.

Mature leaves of this species have a leathery texture which reduces the herbicide’s effectiveness. In this case, you might have to spray the foliage a couple of times before you start seeing the results.

How Long Does Roundup Stay Active in The Soil?

According to the United States Department of Agriculture’s the half-life of Glyphosate is anywhere from a couple of days to 249 days. This means that Roundup can stay active in the soil for a long time.

Even though the chemical stays active, most of it is neutralized by the soil. A number of studies conducted on the topic indicate that Roundup becomes harmless towards vegetation more quickly.

How Can You Protect English Ivy That Have Been Exposed to Roundup?

There is no need to panic if some of them wanted English Ivy has been accidentally exposed to Roundup as it takes up to 30 minutes for the herbicide to be fully absorbed.

Since Roundup is susceptible to water you can use water to wash away the herbicide as soon as it comes in contact with the tree.

Alternatively, you can also use soil, ammonia, or bleach to neutralize the chemical and reduce its effectiveness.


Roundup can be used to kill English Ivy. The most effective way would be spraying the entire Foliage of the tree with a Ready-to-use Poison Ivy Roundup Mixture during spring.
