Mugwort is a perennial invasive weed that can be quite bothersome when it takes root in your garden. It grows up to 6 feet tall and is often mistaken for other non-invasive herbs. Mugwort can thrive in various soil types, from sandy to loamy, but prefers to grow in damp areas such as riverbanks, ditches, and marshy soil. This weed is native to Europe and Asia, but can now be found in many parts of the world.
If not controlled, mugwort can crowd out other plants in your garden, reducing crop yield and threatening the health of your plants. Mugwort is known to release allelopathic chemicals from its roots that can stunt the growth of any other plants nearby.
Fortunately, there are several strategies you can use to naturally banish mugwort from your garden. In this guide, we will outline the best tips and tricks for identifying and getting rid of mugwort.
Why Mugwort is a Problem in Your Garden
Mugwort’s invasive nature makes it problematic for gardeners and farmers. It can cause a variety of problems, such as:
1.1.1. Crowding out Other Plants
Mugwort can grow up to 6 feet tall, and its large size can crowd out other plants in your garden. When it gets too close to your crops, it can create shade and reduce the penetration of sunlight.
1.1.2. Stunting Growth of Other Plants
As mentioned, mugwort secretes allelopathic chemicals that can cause stunting in other plants. This can significantly impact the growth of your crops and limit your yield.
1.1.3.Providing Shelter for Insects and Pests
Mugwort also provides shelter for insects and pests such as the Colorado potato beetle and root-knot nematodes, which can cause significant damage to your plants. Getting rid of mugwort can help reduce the population of these pests in your garden.
Common Symptoms Indicating Mugwort Invasion
If you’re concerned that mugwort has invaded your garden, it’s essential to be able to recognize the common symptoms of its presence. Here are some signs to look out for:
1.2.1. Presence of Large, Green Leaves
Mugwort has large green leaves with a distinctive shape that resembles a feather. These leaves can grow up to 3 inches long.
1.2.2. Appearance of Small, Yellow Flowers
Mugwort produces many small yellow flowers that usually bloom in late summer to fall. The flowers look like small daisies and are in clusters.

Natural Methods to Get Rid of Mugwort
Once you’ve identified mugwort in your garden, the next step is to get rid of it. Here are some natural methods you can use to get rid of mugwort.
Cultural and Manual Control Methods
3.1.1. Hand Pulling
Hand pulling or digging out of the plant can help you get rid of mugwort. Be sure to wear gloves to protect your hands against the allergens found in mugwort.
Mowing mugwort regularly so that it does not produce seeds is an effective way to stop its spread. A height of 2-4 inches should be appropriate.
Putting a 4-6 inch layer of organic mulch over the soil can limit the growth of mugwort. Any weed that grows through the first layer of mulch will be stunted by the second layer and powerless to spread.
Biological Control Approaches
3.2.1. Introducing Natural Predators
Introducing natural predators such as lacewings, ladybugs, and predatory stink bugs can provide an effective way of controlling mugwort infestation.
3.2.2. Use of Soil Solarization Techniques
Covering the area infected with mugwort with a thin sheet of plastic for a few weeks during the summer can kill off the plants that are present by depriving them of sunlight.
