Bill, our lot in in downtown Keaau, they put one layer of landscape plastic on the soil (yes we have soils...) then 6" of red cinder then another layer of landscape plastic (some areas 50# mylar mac nut bags) then 3" black cinders. The weeds have grown through, around & between all of the layers... the cinders do make weeding a little easier, as long as you get them early, before their roots go down into the base rock (less than a month for some of the weeds here) We are taking all of it up because over the years it is just a mess... root matts at the plastic barriers & all.
I have found that the best looking yards havve a tight ground cover, as anything seems to sprout plants (even lava rock - we even have some plants that have sprouted up on our concrete sidewalk with all of the rain recently, the roots are spreading out on the bare, moist concrete!)
