I recently bought a house with a beautifully planted perennial garden. However, I recently identified one fast growing plant as ground elder. It has taken over a couple of beds and seems to be spreading across the yard. I see this is difficult to get rid of and I would love some advice about how to stop it’s spread. Thank you!!

Control is possible

Personally, I do not cut before digging because I like to grab the entire plant. It is easier if you soak the ground before weeding to make the dirt softer.
The places where it is widely interspersed among your plants are much more difficult. Digging as described above will be a multiyear project
Personally, I do not use herbicides but if you do, I would suggest simply dripping a small amount of glyophosphate on two or three leaves of each plant. Do not spray, you will hit everything.
