What You Need to Know
Creeping Charlie is a perennial, evergreen creeper that loves moist, shady areas.
It's found all across the country, except in the Rocky Mountain states. This means you don't have to worry about it spreading in the western part of the US.
Creeping Charlie spreads by rhizomes (underground stems) and seeds, and forms thick mats in the lawn. Be prepared to tackle it early on, as it can quickly take over your yard.
It was used by the ancient Saxons for brewing beer and was brought to this country from Europe for medicinal purposes. That's a fun fact, but it doesn't change the fact that you need to get rid of it!
Understanding Creeping Charlie
Creeping Charlie is a persistent weed that can be a real nuisance in gardens and landscapes. It grows close to the ground and spreads quickly through underground stems called rhizomes.
This weed thrives in moist environments, which is why it's often found in areas with poor drainage. It can also tolerate some shade, making it a common sight in woodland gardens.
Creeping Charlie can be difficult to eradicate because it produces small, white flowers that can self-pollinate and produce seeds.
What Is
Creeping Charlie is a perennial weed that thrives in moist environments, often spreading rapidly through underground stems called rhizomes. It can grow up to 12 inches tall.
This weed is native to Europe and Asia, where it's considered a minor problem in lawns and gardens. It's now found in many parts of North America.
Creeping Charlie's leaves are typically oval-shaped and have a distinctive scalloped edge, often with a soft, velvety texture. They're a deep green color, which helps the plant blend in with its surroundings.
In ideal conditions, Creeping Charlie can produce small, blue-purple flowers in the summer months. However, these flowers are not particularly showy and are often overlooked.
Charlie's Appearance
Creeping Charlie can be a bit tricky to identify, but there are some key characteristics to look out for. Its leaves are scalloped and form on the end of long leaf stalks.
The flowers of Creeping Charlie are light blue-purple and bloom from late spring to early summer. This is a common time for them to appear in lawns.
As a member of the mint family, Creeping Charlie's stems are square in shape. This is a distinctive feature that can help you identify the weed.
Here are some key things to look for when trying to tell Creeping Charlie apart from wild violet:
- Leaves that are heart-shaped with sawtooth-like serrations on the edges are likely wild violet.

What Are They?
Weed killers for Creeping Charlie are a type of post-emergent herbicide that only work after a plant or weed has sprouted.
They don't prevent new plants from growing, so you'll need to spray again in 5-6 weeks to see the best results.
These herbicides are designed to target existing Creeping Charlie plants, but they won't stop the weed from spreading further.

Controlling Creeping Charlie
Creeping Charlie can be a real nuisance, but the good news is that it's relatively easy to control. You can start by hand-weeding, but be sure to remove and destroy every bit of the roots.
Repeated hand-weeding is an option if you've spotted creeping Charlie early, but it's a lot of work. It's better to use a more effective method, especially if the plant has spread throughout a large area.
Smothering it under layers of cardboard or sheets of black plastic is a great way to control creeping Charlie in a large area. This method is especially effective if you don't plan to grow anything in that space for at least six months.
If creeping Charlie has taken over your lawn, a broadleaf herbicide is effective. However, it should be applied in early fall so the plant takes the product down to its roots, weakening it as it goes dormant for winter.
The most effective broadleaf herbicide for creeping Charlie contains triclopyr, generally in combination with 2, 4-D, and Dicamba. Standard herbicides without these components don't work as well.
Always read and follow label directions when using herbicides to avoid harming yourself and the environment. This is crucial to avoid any potential harm.

Herbicide Use
If you're looking to tackle creeping Charlie with herbicides, there are a few things to keep in mind. Employing broad-spectrum herbicides won't eliminate the plant entirely; it will only weaken it.
Using a combination of systemic and selective post-emergent herbicides is the way to go. Systemic herbicides spread throughout the plant, affecting the roots and shoots, which decreases the risk of the weed coming back.
Selective herbicides, on the other hand, work only on the weed they're designed to kill. If you accidentally spray or spill a selective post-emergent on grass or plants, it won't harm them.
Opt for herbicides containing 2,4-D, dicamba, or triclopyr, which are particularly effective against tough weeds like creeping Charlie. Triclopyr is a top choice for lawns and turfgrass areas.
Glyphosate is another option, but it's non-selective and can kill your grass, making it a more challenging choice. Always read your product's label directions for use and wear protective gear to avoid any hazards.

Tools and Methods
To control creeping Charlie, you can use a combination of physical removal and targeted herbicides.
Boiling water can be an effective method for killing creeping Charlie, as it can reach the plant's roots and prevent regrowth.
For larger areas, consider using a selective herbicide that targets broadleaf weeds like creeping Charlie, without harming nearby grass.
Some herbicides, like glyphosate, can be applied directly to the plant's leaves, but be sure to follow the product's instructions and take necessary precautions to avoid overspray.
Manually Remove
Manually removing creeping Charlie is a viable option for small infestations. Wear garden gloves to prevent allergic reactions.
Soak the area with water if it hasn't rained recently. This will make it easier to pull the plant out of the ground.

Put on garden gloves and trim the stems and leaves as much as possible. This will help you get a good grip on the plant.
Carefully grab the base of the plant and lift upward gently. Be careful not to break the roots.
Try to remove as much of the root system as possible. Leaving even a small fragment behind can cause the weed to sprout again next year.
Dispose of the pulled plants to prevent re-establishment. Don't add them to a compost pile, as they will likely take root.

Sheet Mulching
Sheet mulching is a simple and effective way to kill creeping Charlie by depriving it of sunlight.
To start, cut the plant close to the ground.
You can use a variety of materials for sheet mulching, including wood chips, straw, shredded leaves, grass clippings, and compost.
Lay down a layer of wet cardboard or newspaper as the first layer, and follow up with the other materials.
A 4-inch deep layer of mulch is recommended to ensure the plant doesn't photosynthesize.
Reapply the mulch as needed to maintain its thickness until the creeping Charlie plant is dead.
How to Use a Knife

To use a knife effectively, it's essential to wait for the right conditions.
Avoid using a knife in windy weather, just like you wouldn't spray weed killer on a breezy day.
Don't mow for several days before and after using a knife, as it can kill or cut off the parts of the plants that absorb and transport the herbicide.
