Does anything exist that will actually kill wild violets? Nothing I have tried works. Not even Roundup. Not even horticultural vinegar. They'll yellow and look sickly for a few weeks, but not completely die, then come back like they were never sprayed.
I've tried weed killers (Bayer Advanced All in One Weed Killer for Lawns and Ortho Weed B Gone Max) that state on the label that they will kill wild violets, and it hasn't happened yet.
I hate those damn weeds! They spread by seeds, and by their tuberous roots. I had some grub damage, and the grass in that area was dead, but guess what survived just fine? Wild violets! When I dug them up, they had grubs feeding in their roots, but they were still going strong!
If I only had a few, I'd just dig them all up. However, they've spread all over my lawn, and I want to find something to get rid of them. Is there such a product sold???
