I was taught to spray with the nozzle very close to the leaves so the Lontrel is not distributed all over the place. It took me about a week. Very tedious and hot in the outfit. That was also the way I used the Roundup (without the outfit). My neighbor was more generous with the spraying of Roundup, but it still did not help. I bought and used a prayer with a long wand-nozzle for the mugwort and I did not rinse it and have not used it for anything else. I think you'll be successful in just digging out the few plants in your garden. I also have a few in the front yard, and I dig them out every time I see them there, trying to get all the roots. I even had to dig out my rose bush, because the mugwort was right next to it. I made sure there were no roots left and replanted the rose bush. It is still alive. Good luck with your fight with mugwort--
