just put down grass seed? ya got to be kidding! get some branch loppers and start cutting those bushes. dig up them roots. once you've cleared up all that crap start tilling your soil, removing all rocks you find. have your soil analysed by your extension service to see hwat's lacking for proper seed germination. removing the plants will take with them some soil so get a few loads of topsoil. work the topsoil into the tilled backyard. if your soil is acidic add some limestone. then a good nitrogen enriched fertilizer. THEN plant a fescue mix grass seed.
