Natures way ---- Borax. If you apply it in the right amount, household borax is slightly more toxic to creeping Charlie than to grass, so you can kill the weed but spare the lawn. It does have its limits: It's going to burn the grass if you apply it too heavily, and you can apply it only once a year for 2 years before you exceed the level that will harm grass. The proper mixture is 10 ounces of borax in 21/2 gallons of water for 1,000 square feet of infested lawn.
