Hello and thank you for your time. I live in the City of Detroit on the Lower East Side and I am being over come with weeds. There are many to choose from but the most prominent are: Grape Vine, Wild Violet, Poke Weed, Bind Weed, and one that I think is called Elephant Ear (the stalk looks like rhubarb and it has a huge leave). I realize that I will have to use a chemical herbicide to help with this problem but I do not know which one to choose. The weeds are invading my lawn and flower beds.And guidance you can give me will be greatly appreciated. Once again thank you. Sincerely Deb
