I pull by hand. With Bermuda though, I have seen roots 2 feet down so it can be a big effort to eradicate by hand. Most my gardens are grass free now except for a few seedlings that crop up here and there because I have a Bermuda lawn. But one of my gardens now that has so much grass that the only solution I have thought of is to pull all the Irises out, dig down deep and take out all the grass and then replant the Irises. I have never tried Grass B Gone. Maybe it's time to try.
