Has anyone successfully gotten rid of spotted knapweed from their yards? I don't mean a few plants but rather a large number of them? My big boss/kinda neighbor and his wife have a place by a lake in western Montana. He says they've tackled it by fertilizing and planting grass seed. I just have WAY too much and it's encroaching on other things. I hate to resort to Roundup or some other sort of spray, but I'm getting very desperate.
You probably have too much to pull up by the roots. That stuff is impossible. It kills everything around it, even grass. The only thing I know of is a chemical spray like Roundup. Sometimes I have had to use it full strength and carefully spray only the knapweed. Try to get it before it sets its seeds.
