Hi! I live in Grand Rapids, where years ago there was an orchard that farmers planted creeping charlie that is so invasive it's driving my spouse crazy. He keep honeys in the same area. How can I eliminate the creeping charlie without harming the bees? I really prefer not to dig up the whole yard. I've tried spraying vinegar, dawn soap, and epsom salt in spots in the late evening. It kills the grass as well, although it looks like grass may be coming back. Thank you!
