Been taking the weeds (not yet gone to seed) and dirt I dig up with their roots and piling them on to be tamped down into a sorta rammed-earth ramp up to my backyard gate that won’t get muddy or sprout anything. You want to time the tamping for afternoons where a light noon shower turns sunny, so water gets down into the voids and makes the dirt easier to work but when you drive it out to the surface it evaporates rather than soaks back
