LAVEVE Corrugated Metal Garden Edging 8" x 20Ft, Landscape Edging Border for Lawn, Flower Bed, Garden Fence, Paver Edging (Black)

I used this stuff off Amazon for several areas. It has worked well for everything but Bermuda grass...that goes right under it. EDIT to say I didn't leave it that far up in the air though, they are advertising pictures. Mine is flush with the mulch.
