Good Morning, 

Thank you for contacting the U of M Extension Service. 

Please click on the following link about ground elder: https://plants.ces.ncsu.edu/plants/aegopodium-podagraria/   Please review the photos to ensure this is the plant you are dealing with. 

This information states:

Some management options include spraying with herbicides, manually digging or hand-pulling of the plants, and continuously mowing the growth. When using herbicides, care must be taken to not overspray and damaging or killing other plants, including native plants. Digging and hand-pulling may be a long term project with such vigorous growth.

Good Luck!
