How to Remove Burdock From a Lawn

Overview

Burdock is a plant native to Europe. The large taproot plant can produce thousands of seeds each year. The invasive plant tends to like high moisture areas that are rich in nitrogen. The large burs, which hold the seeds, will also get caught on clothing and on animal hair. Left unchecked, common burdock can quickly take over an area. There are two typical methods for removing burdock from lawns: mechanical and chemical.

Step 1

Wear gloves when working with the removal of burdock, as the plant can stain hands a deep green color. According to Washington State University, the plant may also be considered toxic due to its potential diuretic effects. A diuretic is any substance that increases the flow of urine.

Step 2

Dig the long taproot from the lawn using the hand trowel. Remove all of the long taproot, as any small portion will grow back over time.

Step 3

Mow the burdock plant on the lowest setting possible with the lawn mower. This will keep the plant from reproducing. The common burdock reproduces from a large center stalk. From the long cylindrical stalk, emerges the flower head and then the bur.

Step 4

Apply a pre-emergent herbicide or other relevant herbicide directly on the plant in the lawn. This will take a spot application so the herbicide does not come in contact with other plants. Use a small hand-held sprayer or a wick-type applicator. Consult your local agricultural extension service for herbicides that are used in your area. Not all herbicides may be legal to use in various areas around the country.
