That sounds like a good idea. I think i will try it. Living in a condo, I don't have that many weeds, so it is entirely doable. I would think that in place of using a "collar" to protect nearby plants, I could also just use something like holding a trashcan lid vertically between the two to protect desirable plants. Yup, next time I see a prickly thistle growing that i don't want to touch/pull up with my hands, I will certainly use this method -- thanks!
