I'm regrading the side of my house. I have a bed of rock mulch that runs the length of my house and about five feet out. Its about an inch and a half to 2 inches thick. Its 10 years old and not in great condition. My plan was to dig up the rocks, tear up the protective weed blocker, add dirt, rake it, tamp it, add new weed blocker and put the rocks back. But the rocks are not in the best shape, interlaced with dirt and old roots. I'd like to start fresh, but I'm wondering if I could just leave the old layer of rocks there, cover them with dirt and proceed from there. The original plan it super labor intensive and won't look as nice when done.
