I'm trying to get rid of a large (and getting larger) patch of Bishop's Weed along the back of my perennial bed. I've tried using Roundup but haven't had much success. I guess at this point I'm thinking of digging it out as it pops it's nasty little head through the earth and then camping out next summer with a gallon of Roundup. It's a shame...I really love the flower but it's worn out it's welcome.
Anyone have any ideas on how to get rid of this stuff...without killing everything else!
