My ground is so full of rocks with little dirt.

Your lawn's grass will grow better if you remove at least some of the rocks from the soil. It's unlikely you can remove all of them; so don't stress about leaving some. The more rocks you remove, however, the easier it will be for grass to become established. Moving a steel garden rake across the top 2 to 3 inches of soil helps expose and loosen rocks so they can be removed; the larger stones, in particular, take up valuable soil real estate. Another option is to dig into the soil and remove its top 4 inches for replacement with rock-free soil.

I would get a bulldozer & scoop up at least 2 feet of the dirt to a holding area. Shrub roots go down at least 2 feet usually. Go thru it & pick out the big rocks. Little rocks provide the soil with aeration that's good for plants so I wouldn't worry too much about those. Use the big rocks to border flower beds, paint them for a decorative look or whatever you like. Put that dirt back into the graded off area. Add fresh soil on top. Till it together & water it real good so it will settle. If it shrinks too much, add more dirt & water again until it reaches the top again. Plant your plants as usual. :)
