Hedera, which we commonly refer to as English Ivy (pl. Ivies), is a family of around 20 species of evergreen perennial plants. Depending on their surroundings, these woody plants can be both ground creeping or climbing nearby trees, rocks, buildings, and pretty much anything they can lay their stems on. Given a solid base, the ivy has the ability to crawl up and reach heights of more that 30m. On ground level it rarely exceeds ½ feet in height.
As gorgeous as this chef-d’œuvre of nature is, it can still cause mischief around your property if left unattended. It’s considered an invasive plant after all, meaning it’ll not knock on your door to ask if it’d be OK to crash in your yard for the night.
The Dark Side of Common Ivy
Now that you think of it, the ivy is quite the troublemaker. In addition to being an invasive plant which could potentially attach to and damage your property, it is also harmful to children and pets, causing allergic skin reactions from a mere touch, or vomiting if ingested.
The creeping and climbing habits of English Ivy pose a great menace to flowers and trees in your garden, stealing their essential nutrients and water. Its foliage blocks valuable sunlight from reaching other plants, and also creates shelter for different kinds of pests such as mice, rats, birds, bats, and insects. Ivy’s berries also attract wildlife, mostly birds, butterflies, moths, bees, and wasps.
How to Kill Ivy
Your best bet to completely eradicate invasive ivy involves the use of chemicals and about a month’s time for this method to take effect. Before you commence the process, be sure to have the following supplies at hand:
- Rubber gardening gloves (£2 – £10)
- Garden shears (£5 – £20)
- Pruning saw for thicker ivy vines, if any (£10 – £20)
- Spray bottle or sprayer (£10 – £20)
- Glyphosate weed killer (£20 – £30)
- Long sleeves, long pants and boots (£5 – £20)
- Strong patience (priceless)
Got them all? Good, let’s move onto the steps to kill ivy.
For ground covering ivy:
Step 1. Find and mark all the plant’s base roots.
Step 2. Leave around 1-2 feet worth of ivy coming from the main roots untreated, for later.
Step 3. Start cutting the ivy in patterns, simultaneously pulling out each section.
Step 4. Pile up everything you’ve cut to dispose of it after the chemical treatment.
Step 5. Spray the freshly cut vines and remaining leaves (from Step 2) with a weed killer containing Glyphosate*.
Step 6. Repeat this process every few weeks until the ivy is defeated for good.
*Ivy’s leaves are glossy and impenetrable when it comes to most herbicides. Glyphosate however is a chemical that can be absorbed by the leaves and enter the ivy’s vascular system. This slow but efficient method causes the plant to die out in a matter of weeks. DO NOT spray over plants that you wish to preserve.
For climbing ivy from trees
Step 1. Cut its vines at waist level 3-4 feet above tree trunk base with the garden shears, all around.
Step 2. Leave the ivy that remains on the tree to dry out and die off within a month or so. Do not pull the vines unless you’re sure they are dead. Otherwise you will damage the tree’s bark.
Step 3. Remove as much ivy roots as you can around the trunk by hand, leaving a safe zone of at least 3-4 feet radius. This way you can act fast if new ivy vines emerge.
Step 4. For what’s left on the ground, apply the same procedure as killing ground creeping ivy.
Remove ivy from walls
Step 1. Pull out each vine gently to prevent damaging the wall.
Step 2. Leave any leftovers to dry out with time, so they could become easier to remove.
Step 3. Apply weed killer containing Glyphosate to the ivy’s ground roots to prevent it from growing back again.
Step 4. Scrape off remaining rootlets and tendrils with a steel brush. For wooden house exterior and wooden fences use a sander instead.
Home Remedy Alternatives
Not a fan of chemistry, eh? No worries, we got you covered. Here are 3 non-toxic, Eco-friendly methods to deal with overgrown ivy. Note that these require time, usually months, before you can see any positive outcome.
The good ol’ white vinegar method
Arm yourself with a garden sprayer or a regular spray bottle. Fill in the container with a mixture of 80% water and 20% white vinegar. Spray the ivy plants thoroughly, making sure you don’t affect any other plants you don’t want to get rid of. Wait for a couple of days and inspect the result of your efforts. Pull out and remove any dead ivy and re-apply the same solution as much as needed.
Duct tape, table salt, and water
This trick is suitable for treating thicker vines. Make a fresh cut on each one using your garden clippers, wrap them around with duct tape to form something like a cup. Pour ¾ table salt in each cup and apply a bit of water. This way you attack the ivy’s vascular system and the plant should be completely dried out within a couple of months.
Create thick layers of mulch by using old newspapers, cardboard, dead leaves or grass, or other similar matter, and place them on top of the area where ivy grows. Your goal here is to suffocate the ivy, preventing it from receiving its life-sustaining resources like light, water, and air. As for those mulch materials, they are biodegradable, meaning they will decompose with time and become one with the soil.
