Wild violets taking over my lawn

Wild violets taking over my lawn

Any advice on how to get rid of them? Too many to pull up. I have tried Ortho Weed b gon concentrate at the recommended dilution, but it doesn't seem to faze them. Of course, it's only been a couple of days, do I need to be more patient? My fingers are getting twitchy for the Roundup, but I don't want to kill my grass.


Violets are broadleaf plants and any good weed and feed should eliminate them in three to four weeks.:D
