even spraying the area with a chemical like round up would work killing
the grass and weeds then leaving simmple dirt to turn over and plant
in, or for a more organic approch a strip of 6mill clear plastic
placed over the area would work let the sun cook and kill the grass
and weed seeds in the soil leaving you with clean sterile soil to plant
in (might want to add some manure or fertalizer to the soil after if
useing this method and of course the plastic only works when it is hot
and sunny out side
