Hardiness Zone: 5a

I have had luck removing unwanted plants without poisons, by covering the area with old carpet or heavy fabric and covering that with mulch and rocks to look nice. It is called "solarizing" and it also kills any pathogens, germs, etc. I keep it on a full season.
It is healthier to wildlife, pets, and kids than sprays. (04/27/2007)
Have you tried spraying it with Roundup? That's supposed to kill anything. (04/28/2007)
I'd check with a local horticulturalist. Your extension agent might have info. You have to be impressed with a plant that resilient, especially that far north. Maybe there's some research being done on it. (04/28/2007)
