Cirsium Heterophyllum out of control
I'm not sure what I should do about my CH - I got it last year and it didn't do a lot, but this year it's back with a vengeance! You can see it popping up all over the place - see right to the right of the pic it's sneaking up next to an echinacea. Is it going to stop other things growing? I don't know whether to just leave it be or get involved somehow?? Any help gratefully received.
