Remove or Rooter grass for a garden

I am planning on turning a section of my lawn into a garden. My question is, do I need to remove the grass or can I just use a rooter and plow it under?

Thanks

 

The standard method is to kill the grass down, roots and all, with a product such as RoundUp. RoundUp is non-selective and does not know the difference between your finest landscape plant and a weed so apply to the area you wish to kill only.

Do not walk in there until it has dried. My Dad left the cutest dead grass "footy-prints" across Mom's lawn when he forgot that one.

RoundUp is neutralized by soil contact and has no residual action so is good for this purpose. It is available in most any garden center. Just follow label directions and cautions.

Once the lawn area you are going to use for a garden is killed down you can then go ahead and rototill. Doing so without killing down the existing lawn will mean you are just unplanting and replanting the lawn each time the tiller blades go around.
