Hi. I have only lived here for a little over a year now so I am not sure what the proper name is but we have the sticky burrs that grow on the grass. I'm sure I don't need to tell you that they hurt!! We've got quite a few acres but really only want to treat about 3 acres that surround the house so my grandkids and dogs and us too can go walk around. My poor dogs have become experts at getting them out but I still need to get rid of them. Any advice?
