How to Get Rid of Invasive Mugwort

7 Comments

mugwort
Mugwort is a pesky plant with an equally displeasing name. It has become an excessively problematic plant in Tennessee and Georgia in recent years where it is currently considered an invasive plant. Mugwort grows from rhizomes that are extremely hardy and readily productive. Mugwort releases seeds in late summer in warm regions like the Southeast, which creates double trouble for those wishing to stop its rampant growth.

Invasive plants are becoming more of a hot topic than ever before. Most invasive species arrived in the U.S. under innocent circumstances. Mugwort (Artemisia vulgaris) came to the U.S. from Europe or Asia as a perennial herb that debatably has a number of health benefits. In its native environment, mugwort was most likely prone to disease and environmental conditions that prevented it from overtaking other plants.

Like other invasive species though, mugwort has no natural predators in its new environment. Sometimes a plant that is removed from one ecosystem into a new one is capable of outcompeting the native plants for nutrients in the soil, or for sunlight, or for other necessities for a plant’s success. This is the case for the mugwort plant.

How to Identify Mugwort

Mugwort is also known as false chrysanthemum. As the name implies, the foliage of the mugwort looks strikingly similar to that of the chrysanthemum. The leaves smell similar to those of the chrysanthemum, too. However, mugwort is simply a cleverly disguised weed that is sneaking into gardens everywhere.

Mugwort is worth adding to your list of most unwanted vegetation. And, it is an important plant to identify as it begins to invade other regions. You’ll want to know this one when you see it. Here is a link with some excellent images to help you identify mugwort.

How to Control Mugwort

Some invasive plants, like English ivy for example, are planted for a reason. Gardeners like the appearance and behavior of English ivy, and it is readily available to purchase. Research concerning how to control and eradicate it has been conducted. Mugwort, on the other hand, is sort the new kid on the block that no one really knows anything about.

Mugwort is not a plant that a typical gardener would plant purposefully. The spread of mugwort occurs when a gardener purchases a plant that has been extracted from the ground where a mugwort rhizome may have inadvertently been collected, too. So, research on how to control and eradicate this pest is preliminary.

One thing known is that the rhizomes are very hardy and they will produce a new plant from a very small piece. Don’t try to chop the rhizome up. Herbicidal treatment for weeds is recommended. However, your ornamental plant that you purchased with the sneaky mugwort on the side may not withstand the herbicidal weed treatments. The decision may be a difficult one if you already have a mugwort in your midst.

If you have not been exposed to a mugwort in your landscape yet, the job for you as a conscientious gardener is to be aware of this plant and to be able to recognize it. Once you can identify it, be careful not to introduce one into your own garden. If you do, it will likely spread from the garden into your yard and right out into your neighborhood and beyond.

Invasive Plant Awareness

Spread the news about mugwort and other invasive plants before these plants spread themselves into your region. Be aware of what plants are considered dangerous in your area. Share that information and knowledge with your neighbors and fellow gardeners.

Organize a community group dedicated to education concerning what plant varieties pose a threat to the native plants. Encourage your community to avoid garden centers or nurseries that sell plants known to cause harm to the local ecosystem. And finally, contact your local extension office to learn more about how you can help tackle the issue of invasive plants.

    My flower garden has become infected with mugwort. I am elderly and unable to do a lot I sprayed and killed the top but then the roots flourished again . I used Brushtox to spray which is lethal to other invasives. What can I do to get those roots to be gone forever?

      You don’t. It can’t be done! It has spread into New England, and nothing I do has slowed its spread in my yard and all my flower and vegetable gardens!

    I have found some small relief. I put down thick landscape fabric over it. It started growing at the edges of the fabric. I hit it with a squirt of vinegar at least once a week and it turns brown within hours. It does start to grow back in some spots about 5 days after I “vinegar” it. I keep hoping that eventually it will give up!

    The best thing you can do is make peace with this beneficial plant and learn how to love it and live with it. Do your research first about Artemesia Vulgaris or (Mugwort) as they call it.

    I purchased a Halo Dogwood from a garden center that had some sort of leafy growth in the soil of the container. I picked the weed out and planted the Dogwood and suddenly that weed was al through my garden – it was quite aggressive. It’s mugwort (looks like chrysanthemum leaves) and I still have it today despite weeding. I pick it out constantly. I just planted hosta over it, hoping to deprive it of sunlight and diminish its growth.

    Mugwort is rife throughout my flower garden. Last autumn, I hacked a dense mini-forest of mugwort down to the soil. This spring, literally thousands of mugwort sprouts, ranging from 1/2″ to two feet, smother the garden.

    Every day, I confront interminable plucking. The stubs of the hacked weeds from last year now sprout shoots, and some of their rhizomes extend through through the dirt to create new mugwort. A rainy day followed by sunshine results in myriad mugwort sprouts, and they soon intertwine with the garden’s flowers.

    The nearest analogy to the unstoppable spread of this weed is the movie “Alien.” No matter how many you wipe out, more keep coming.
