I have a particular persistent viny weed with a small purple flower (during sping) in my yard and small light purple tinged leaves. I noticed it in limited quantities last year and it really propogatted this last year. I've tried every known weed killer (except the whole yard killers) without sucess. This stuff if weaving in/out of my grass and is near impossible to pull up. It has lots of little root systems interconnected and I can never pull up all of it.
I don't want to kill my whole yard just to get rid of this pesky little weed, are there other options?
