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?
That’s going to be region-specific. If you share that people might be able to help, though I’m not necessarily an expert.
