I don't think grass will grow in my yard...at least the dandelions make it look green! Plus they spread from my yard all over my neighbors yard, which is my silent revenge for their complaints about my lack of yard work when I was in the hospital last year.

I just don't like the dandelions where they are growing through the sidewalk and patio around my house. Though milkweed is the worst offender there, and since the roots are below the concrete I can't even pull them up. Vinegar works fairly well on milkweed too though.
