I am concerned because I used a mantis tiller on it. I was told all the root pieces sprout. It sounds like I have really spread it through my garden. It is really thick in my rhubarb patch. I have spent so many hours trying to pull it out of there. I am thinking of using an herbicide on the quack grass that is around the boundaries of the patch. I read that Ortho's "Grass B Gone" will kill it. I thought if I sprayed on the edge of the patch maybe it will follow the roots and kill the grass that is among the rhubarb. Thank you so much for replying.
