Getting rid of thorny thisle

13 years ago

I think we've posted this before and I looked for it but couldn't find it. Thorny thisles pop up in this one flower bed all the time. I dig them up and they still come back. Anybody have a solution? You can't use round-up because that would kill anything near it. Would weed-b-gone help?

You could paint Roundup onto the plants, thereby preserving your desirable plants.

Even so, it sounds like a perennial. Thus, you'll have to paint it more than once.
