How to Kill Creeping Charlie

This shade-loving groundcover grows fast — so fast it can take over your yard and become a plant nuisance. Here's how to get rid of creeping Charlie when it grows in the wrong place.

Creeping Charlie

Creeping Charlie is a rapidly-spreading, matted garden plant some gardeners refer to as ground ivy.

Creeping Charlie is a fast-spreading groundcover that's classified as an invasive weed in many states.

Creeping Charlie, also known as ground ivy, is a shade-loving perennial that’s grown as groundcover. It’s also sometimes used in containers and hanging baskets because it’s easy to grow and looks lovely trailing over the sides of the pot. But once it escapes the place it’s planted —and it always escapes, thanks to its prolific seeds, rhizomes and stems that grow roots — creeping Charlie becomes an aggressive, invasive plant that will take over your lawn and garden. Read on to learn how to get rid of creeping Charlie when it becomes a problem.

Botanical Name: Glechoma hederacea
Common Name: Creeping Charlie, ground ivy, gill-over-the-ground, alehoffs, cat’s foot
Hardiness Zones: 2 to 12

Identifying Creeping Charlie

Several types of plants get called creeping Charlie, including Swedish ivy and Lysimachia nummularia (aka Creeping Jenny or moneywort,) but the nuisance plant we’re talking about is Glechoma hederacea. Creeping Jenny looks a lot like creeping Charlie, but Jenny doesn’t have scalloped leaves.

Creeping Charlie is a cousin to mint, so it has a strong, minty odor when you crush it. Charlie’s leaves are bright green, round or kidney-shaped, and have scalloped edges; its stems grow into thick, carpet-like mats. A variegated version has pale green leaves tipped in white. Charlie’s a perennial, so it comes back every year, like it or not. In the spring it produces small, funnel-shaped blue flowers.

Like most invasive plants, creeping Charlie was brought to North America by well-intentioned Europeans in the 17th century who thought it would make a great groundcover for shady places where little else would grow. And grow it did. A few centuries later, many states officially listed creeping Charlie as an invasive weed. Connecticut has even banned it. Creeping Charlie isn’t vulnerable to any pests and diseases. Heck, goats won’t even eat it because a bellyful of the stuff will make them sick. Here’s how to kill creeping Charlie.

Hand-Pulling Creeping Charlie

If the creeping Charlie you've targeted for death is near edible plants, or if children or pets play nearby, don't spray it with industrially produced herbicides or weed killer. Glyphosate, the active ingredient in many popular weed killers, has been linked to cancer. You can pull Charlie out, by hand, no chemicals needed. Yes, you can do this. You’ll just need time, muscle and a commitment to gardening sustainably. Here’s how:

1. Trim the leaves and stems from creeping Charlie so you can see where the stems emerge from the ground. Bag up the trimmings and: A. Throw them in your compost pile IF you know your compost gets hot enough to kill weed seeds, or B: Throw them in a trash can. Don’t just leave them on the ground. If you do, they’ll grow roots from the stems and establish a whole new patch of Charlie. We told you this stuff was hard to kill.

2. Soak the soil. Use your garden hose to saturate the soil around the creeping Charlie. Give the water an hour to soak into the ground. You want the water to loosen the roots’ grip on the soil so it’s easier for you to pull the roots out without breaking them off in the ground.
Alternative plan: Wait for a rainstorm to soak the ground for you naturally.

3. Loosen the soil with a pitchfork. Gently lift up forkfuls of soil to expose the roots and rhizomes of Charlie.

4. Pull up the plants. Hold on to each Charlie plant at its base and pull it out of the dirt, slowly but firmly, being sure to remove the roots with the plant. For deep roots, use the pitchfork to loosen the soil farther down so you get the plant and roots in one pull. Put the whole plant, roots and all, in that bag with the trimmings. Remember, each time you bend down to pull a weed out by the roots, it’s just like doing a squat in the gym. You’re getting fit and the creeping Charlie is getting dead. Strong legs, and a weed-free and herbicide-free yard. It’s a win-win.

5. Look for pieces of plant and roots you missed. Use a trowel or weeding fork and poke around in the soil to seek out remaining roots or plants. If you leave a scrap of Charlie’s roots or stems in the area, they’ll grow into a new plant.

6. Repeat in a few weeks. No matter how thorough you are, you’re going to miss some roots. Keep an eye on the area, and pull up new creeping Charlie plants by the roots as soon as you see them. Lather, rinse, repeat. Hand-pulling weeds is eco-friendly, but slow. It’s going to take a couple of passes to eradicate creeping Charlie from the spot.

Killing Creeping Charlie With Herbicides

If your patch of creeping Charlie is too big to pull out by hand in this lifetime, you may have to resort to a chemical weed killer. You can use a product that kills every plant in the area and then start over from scratch and replant. Or you can spray just the creeping Charlie with a lawn-friendly product, like a broadleaf herbicide. Follow manufacturer’s instructions, but here are some tips on how to kill creeping Charlie:

  • The best time to spray weed killer on Charlie is in the fall after the first frost.

  • Pick a day with no wind so the weed killer doesn’t blow onto plants you want.

  • Make sure it’s not going to rain or snow within 24 hours after you spray.

  • After you’ve sprayed the area, leave it alone for the winter. The creeping Charlie will die, and its roots will compost into the soil.

  • In the spring, rake up any dead plant debris, amend the soil and plant something you like.

Creeping Charlie’s Good Points

OK, even a creep like Charlie has some benefits. If you can keep it under control, creeping Charlie has powers that can be harnessed for good.

It’s edible. Ask a wild-food forager and they’ll tell you Charlie’s young leaves have a mild mint flavor and are delicious tossed into salads. Leaves can also be cooked like spinach, or added to soups or omelettes. You can also make a tea from creeping Charlie leaves.

It’s a good lawn substitute. If you’re looking for an eco-friendly, low-maintenance alternative to turf grass in a shady area, creeping Charlie is a good choice. It grows in thick mats you won’t need to mow. There are noninvasive groundcovers that are better choices for turf substitute, though.

It’s good for erosion control. Creeping Charlie grows in shady conditions and in poor soil, so if you have an area prone to washout, creeping Charlie can keep the soil in its place.

Pollinators like it. Creeping Charlie’s flowers produce nectar in the spring and early summer that's loved by bees and butterflies. Your weed is their food.
