How can I get rid of bishop's weed?

Garden Experts

I have taken on a house and have tried desperately for a year to get rid of the bishop's weed present in the flowerbeds. Unfortunately, it always returns, probably because there are still root remainders in the soil. Can you recommend anything?

Dear Mr. E., use Finalsan GierschFrei, by Neudorff. This is an organic herbicide for combatting bishop's weed. You can stand and watch as it dies within a few hours – including the roots!
