Ruts don’t necessarily mean the end of your lawn. There are ways to salvage your grass after a car mercilessly ruins it. Get a spading fork and loosen the top layer of the compacted soil. Move it back and forth at a 45 degrees angle until you’ve raised all the earth.
Next, fill in the rut with a 50/50 soil and compost mix. Now, place the sod back on and put seeds in any bare spots.
