I believe that this is what the weed is called, here is a picture
It is very invasive and I don't know how to kill it. I tried Weed b-gone but it only kills the leaves and does nothing else. It's hard to root it because its root are deep. I live in Canada and there isn't that many chemical options to get rid of this annoying weed. However I will be traveling to North Carolina for xmas and I was hoping to get something to destroy this weed.
What product do I need to get to annihilate this weed? I have this weed in my moss garden and grass. I also have a dog, so I am hoping for something that will kill this weed and not harmful to my dog in case she eats the product by accident.
