edging that lasts
I am trying to find a product that I can put on the edge of a planting area (for shrubs) that will effectively raise up the edge of the planting area, so I can plant my shrubs higher, and they will have a larger volume of dirt to put roots into.
This area faces the street, so appearances matter.
I have tried 10x8 inch pavers on their side, but they are fairly thick, and take up more of the "growable area" than I would like.
Would a few sections of 8-foot board do well?
Thanks for any thoughts.
