I have a huge area that was overgrown with many weeds when we bought our house, among them bishop's weed. It sounds like short of lots of roundup, and/or many hours of labor, I'm unlikely to be able to get rid of it.
I'm wondering if it might not be best to just make peace with it. It seems that most perennials compete with it quite well.
If I just clear areas for new plantings, is there any big negative to just leaving it? Does anyone know if it would endanger any plants I might add to the garden?
