I love this plant! However, I would like to curtail its spread in one small area in the corner where I have astilbes. I wonder if a barrier such as a rock border would be sufficient. If not, is there another barrier that I could use that could possibly be as easy? Thanks!
Unfortunately, placing rocks along the border will not stop the Pachysandra plants. You will need to use a barrier edging material.
An edging material that goes below the soil surface several inches will be your best choice.
