Q.Pachasandra
My Pachysandra is growing over my walk. How is the best way to trim it back? When?

You can cut the ground cover back in the spring.
Running a lawn mower over the plants and keeping the level of the mower at 4" will cut the plants but not damage the crowns.
If you are trying to remove the plants entirely, here is a link with more information.
