alternative to mulch over landscape fabric
I have a huge backyard and you can just imagine the weeds I have to deal with every spring! Years ago I put landscaping fabric down and mulch/wood chips over it. I have inadvertently created some fantastic "soil." The mulch has broken down and there are more worms than I can shake a stick at. Of course the weeds love this medium and are growing on TOP of the landscape fabric. Does anyone have any better solutions to weed abatement? (besides round up, of course)
I remember reading in a book? on-line? somewhere that there exists some sort of gravel that will eventually knit itself together forming a good weed barrier. Anyone know what kind of gravel this is and where I can buy it?
