@jimhd, Jim, when I first started converting my backyard to flowerbeds, it took a large part of one summer to dig down to whatever lies deeply beneath TX to remove about 36" of Bermuda from parts of the yard. Incredible root system that allows Bermuda to spring up between cracks in sidewalk joints! Luckily, I was younger and stronger then and probably increased my muscle mass by inches!! vbg

When I eventually hired a prof. landscaper to convert the entire back to flower/veggie beds, I left only one small patch of grass. He had the equipment needed to upload the Bermuda before designing and adding new soil for the yard. Thank goodness!!!!
