Q.Do I have to add lining under the soil
Do I have to add lining under the soil to an edging on a paved surface? I want to create an edging along my side passage and I was wondering if I need to add any sort of lining (plastic?) before I lay down the soil?
I would use a lining or protective barrier up against your foundation.
I would certainly check with your local home improvement store for the proper materials for this application.
