I'm pulling up the mulch and fiber around my house from the previous owners. It was poorly laid and it turned into a big weed issue. Some parts they only put mulch down and no fiber/plastic. I've sprayed RoundUp a couple of times and there are still some small weeds coming up.
Would tilling around the house help or would breaking loose the top inch or 2 of soil be enough? I'm going to be putting down fiber again with washed river rock. I'm not putting any plants in the rock this year. Possibly next year.
