How do I get rid of this pest? I don't know why but it has decided to invade my property and as much as I pull it up, it keeps coming back. I pull the entire root and its fairly easy in that most of the yard is sand. It's not in the lawn but just about everywhere else. How does it spread if I pull it before it seeds? And if I am pulling it, how is it coming back? My yard is pretty much the same as it has been for years with no major import of new loam or plants yet this keeps getting more and more prevelant. Is it in the mulch? Any ideas?
