as you can see in the third pic, all of the dirt out in the field behind my woods is basicly sand. so what me and my bro did was dig hole then go down to the lower level in my front yard and dig up some of the nice black dirt and push it in a wheel barrel allll the way behind the woods tiring as hell but finly got it done, then out about a cubic 4 inches with potting soil so thers a lot of food when they start out.
