what's the best treatment for spotted spurge as it's very prevalent this season. As our lawn continues to slowly improve from prior grub damage, the bare spots have been taken over by the spurge. I've tried a couple different weed killers that claim they are effective, but saw little to no killing. Apparently, unless you get them when they are young, they're much harder to kill; similar to crabgrass. Pulling them out is futile. I may just wait till next Spring then use a pre-emergent, but can't stand the look of them.
