Question
I just spread the lawn with weed killer (Weed B Gone Liquid), will this kill the onions? If so, will they come back next year? If not what will?

Answer
The onions can be tricky and persistent. You'll most likely see them popping up each spring regardless of what you do. That said, if the weed killer was sprayed correctly, it should do the trick, at least for this season.
