Good morning all. I use grass-be-gone. I spray every two weeks. It takes respraying to wipe out the grass. My question is will GBG kill irises? No doubt roundup will kill everything! I have had luck painting some roundup on grass that is close to other keeper plants, but I take the risk of drift. Roundup will travel thru the air. If it's windy at all, don't put any round up anyway near anything you want to live. Remember to mask up and wear googles always.
