Considered to be one of the most resilient and difficult to control weeds, Creeping Charlie can easily take over a lawn in a matter of weeks. Here's what you need to know about killing creeping charlie, either with a herbicide or by pulling it out by hand.

hash-markWhat Is Creeping Charlie?

Also known as Glechoma Hederacea, Creeping Charlie sounds like a brand new horror movie villain, but it’s actually just a common weed. It’s just a villain for your garden. What’s more surprising, too, is that it’s not an ugly plant. It’s a fresh-smelling member of the mint family known for its small stature and purple flowers. It can grow anywhere from two inches to two feet tall. 

Unlike many other weeds, Creeping Charlie is a medicinal plant originally brought over by British settlers. It’s a perennial, so it can last up to two years on its own. It now is more famous for being able to “creep” all over flower beds, butting everything else out of the way.

If there’s one thing that creeping plants are good at, it’s getting good ground coverage. In theory, you could use creeping charlie as a ground cover, but in practice, most people would agree that it’s an eyesore, and your HOA will probably write you up for weed growth. It’s best not to chance it.

The most popular way to get rid of Creeping Charlie is to do it by hand, and admittedly, it can be pretty brutal to do so. However, this is the only way to make sure you don’t have to deal with chemicals that could potentially harm your pets or kids. Here’s how to do it:

  1. Get your supplies in order. You will need gardening gloves, gardening shears, a pitchfork, and a trowel to get started. You will also need a waste bag and access to a water hose.
  2. Start by trimming your Creeping Charlie down to a pullable length. You want to use your garden shears for this. Pullable is up to you to define, but it’s usually two to six inches in length.
  3. Use your garden hose to soak the soil. You will want to saturate the soil and let it sit for half an hour to an hour. 
  4. Then, grab a pitchfork and loosen up the roots around your Creeping Charlie. You want to loosen the soil until you see tiny white roots. (They’re called rhizomes!)
  5. Grab the plants up by the base, and remove the entire plant. Place any Creeping Charlie you’re able to pick up in the waste bag. If you have a very stubborn plant, use a trowel or a pitchfork to loosen the roots. 
  6. After you’re done, use a trowel to look for any leftover rhizomes. Pick them up and toss them. 
  7. After a couple of weeks, repeat the process. The hand-picking process will usually need several repeats before it’s fully successful.

If you want to go for the manual option, then spring is the best time to start. Spring is usually when the roots are at their weakest. You also will be able to nip the problem in the bud, simply because the plants haven’t fully matured yet. 

Since you often need multiple passes for this to be totally successful, starting early also gives you time to enjoy a weed-free garden.

If you are more of a convenience-oriented person and don’t have much to worry about in terms of pets, then you can usually invest in some quality herbicide or weed killer to get the job done. Here’s how you can kill Creeping Charlie with a chemical aid:

  1. Start by picking out your herbicide. Much of your ability to succeed when buying a weed killer for this particular plant, it’s often best to seek out an herbicide that has been rated for killing Creeping Charlie. You can find out whether or not the herbicide you picked is good for this by looking on the package. Choose a home use spray, if possible. 
  2. Mix your herbicide. Most herbicides will need to be diluted to be safely sprayed in a garden. Check your herbicide’s box to see how much water you need to mix before you can spray it in. Make sure your herbicide is mixed thoroughly. 
  3. Get your pets and children indoors. You do not want your dogs or kids to make contact with the poison. 
  4. Spray the area affected by Creeping Charlie. It’s generally best to spray a moderate amount. You want to make sure that the weeds are fully wet but not absolutely soaked. After all, herbicide can potentially harm grass and other flowers around the area. So, don’t use more than you have to. 
  5. Do not allow your pets outside for at least 24 hours. To stay on the safe side, you should refer to the instructions on the back of your insecticide’s package to see how long it’ll take before it’s safe to hit your yard again. 
  6. Wait. You should be able to see the Creeping Charlie die out fairly quickly. When you notice the plants wilting up, pull them up by their roots and dispose of them. 
  7. To be extra thorough, grab a trowel and inspect the soil. Pull out any rhizomes that you see, and dispose of them in a waste bag. You need to make sure that the entire plant is dead; roots included!
  8. Check to see if you need to reapply your herbicide. Though it’s somewhat rare, it’s possible to have your herbicide kill off all the Creeping Charlie in one shot. 

hash-markIs Using Chemicals To Kill Creeping Charlie Safe?

Yes and no. All chemical weed killers will involve some level of risk to the wellbeing of people and animals that call your yard home. Some, such as natural vinegar herbicides, can kill Creeping Charlie but may cause mild irritation if it gets into your eyes. 

Others, such as the corporate-made cocktails like RoundUp, have been linked to increased risk of cancer in both people and animals. If you are concerned about your sensitivity to chemicals, then you should opt for a natural herbicide or just pull up the Creeping Charlie by the roots.

Unlike hand-pulling, which has its optimal time in the spring, using herbicide is the best option in the fall. This is the best option for getting fully matured Creeping Charlie under control, right before the plants start sending out seeds.

A typical herbicide is a great go-to for people who have to have a last-minute fix. It’s fast-acting, so you won’t have to worry about having it be too late to be effective.

hash-markAlways Pick Those Rhizomes!

Remember when we mentioned rhizomes, those petite white roots that are deep in the ground? They are far more important in eradicating this weed than you’d think. The reason why Creeping Charlie is so hard to get rid of is that even tiny rhizomes can sprout into full-blown plants again. 

Even if you’ve trimmed the Creeping Charlie down to the nibs, if you have roots and rhizomes underneath your soil, you can guarantee it’ll come back. Since the roots of this plant are so resilient, it’s easy to see why it’s known as the “weed that keeps coming back.”

hash-markConclusion

When it comes to weeds, few are as difficult to fully remove as Creeping Charlie. While it may have been prized as a medicinal plant with a punch of minty flavor in the past, today, it’s a major eyesore. Once it creeps into your garden, you need to go on the offense. 

Like with most other weeds, you can choose to use your hands to get rid of the weeds if they’re still youthful. However, tougher, more mature Creeping Charlie is best killed off by the use of commercial herbicides. No matter what you choose to use, make sure to get to the root of the problem. Otherwise, Charlie will come creepin’ back!
