Hey all, I need an ID on this type of briar. They are all over my wooded back yard on a huge patch and are a pain to pull. They get to at least 10 feet high...grow straight out of the ground in long stalks with hooked shaped thorns all over them. Red welts appear on my skin when I get stuck with one and it bleeds, then itches for a few days, then subsides. They are whip like when you first try to pull them while still green. I believe the root system is a rhizome. They die off in the winter and turn woody and brown and are easy "crunch" when stepped on, therefore, easier to clear when dead. I had cleared out a section and we burned all the pieces...now...new growth...green and grows fast! I applied a gallon of weed-be-gon concentrate to the entire area and they are only wilted not dead. What are they and how do I kill them!!! I want to plant grass here but, I can't seem to get rid of it! I attached a picture...a brown dead winter stalk and a green one...can post a better picture later today if needed. Just let me know. Thanks to all who can help me kill this!!
