I am planning on killing my lawn and filling the area with raised beds with gravel in between the beds. I will be using the sheet mulching strategy to kill the grass. I’ve used this strategy successfully to prep for my existing beds. My question is this: should I put a layer of anti weed tarp before installing the gravel, or should the sheet mulching do enough to prevent weeds?

    Just curious why gravel over mulch?

    I have both and I wish it was all mulch.

    Sheet mulching is great for the first few years but the cardboard will break down and you’ll have weeds again. With mulch you can just lay down more cardboard and go again. It’s not that easy with gravel.
