We have creeping charlie in our grass in three different areas. I have used Otho Weed B Gone with success in killing it and not harming the grass. My problem is that I let it grow and spread and do not take the time to spray and kill. I have to keep it pulled as it wants to invade one of our daylily beds. I plan to take the time this spring to spray and kill it all once and for all. If it is in your grass, read the back label to see if it is safe to spray on your type of grass. If pulling it by hand, be sure to put it in a trash bag to discard and not throw it on your compost pile or somewhere else because it will take roots and keep growing there.
