landscape fabric over grass?
I have a very large mixed tree/shrub border around my backyard loaded with conifers (some of them interesting, some not so much). It's also loaded with grass, since I didn't create a bed per se.. I just planted stuff directly in the turf.
Anyway, things have gotten to the point where I can't mow between plants anymore, so I need to kill the grass and mulch the entire area (either wood mulch or stone).
I don't think roundup is an option, as I think I'd kill many of my plants. It's a large area with many plantings, completely covered in grass, so I think it would be next to impossible use roundup safely.
I'm sure someone will suggest laying down cardboard.... with mulch on top... but I would need a very large amount of cardboard. I'm not saying it can't be done... but it wouldn't be easy.
I tried using a layer of brown packing paper with mulch on top this spring on part of the yard and that proved to be a complete waste of time, as some of the tougher weeds busted right through.
I do have a roll of landscape fabric... Yeah, I know it's evil. But what I want to know is if pea gravel (or the like) over landscape fabric will kill the grass. Is this possible? Or will the grass simply plow right through it?
