Ortho’s Killer Concentrate targets chickweed, clover, and oxalis without touching the rest of your lawn once it’s mixed and applied. This is a post-emergent formula, so it goes to work on weeds that are already up and growing, and it’s rain proof so a surprise shower won’t wash away your effort. At 16 ounces of concentrate, one bottle mixes into enough solution to cover a fair stretch of lawn. Use it any time during the growing season whenever those weeds show up.
