So the cardboard helps the Glyphosate?

No, the cardboard smothers whatever the glyphosphate didn't kill. If you
don't want the agent orange approach, run over the whole thing with a good
strong mower, then mulch heavily with cardboard, dead leaves, anything that
makes a barrier and will rot. If you do this in the fall, a rotovator will
finish the job in the spring. Also a good way to convert useless sod into
useful veg garden! (Am I the only one who finds the garden space creeps
into the lawn?)
