Yup they will regrow from broken roots... sorry!

I havent found them to do so. unless they are the bulbous buttercup.

just keep at it and they will get less and less . you will win in the end . i did it with that japanese knot weed . i dug the worst out then every shout i sore now i get none.

Oh dear, Moongrower, thanks but no thanks for your answer. I have a lot of work ahead of me then.

As NP says just keep digging away, they will go in the end.

As long as you get the growing tip out then they do not grow from broken roots like Dandelions etc. At least not in my excperience that is. They do spread like mad from runners from any where where there is a plant and they do seed all over the place too, but once the growing point is removed then that is it. (Creeping buttercup I am talking about).

Your right OwdB. not always easy to get the growing tip though

just dont give it a chance its not as hard as it seams you just got to be consistant .

Tell me about it. I have just been doing the first 2 feet of the borders and edging the lawn at the same time. Grass with buttercups and daisies in it might look nice, but...................

i think that asian knot weed is very nice looking but like you say not everywear . believe us when we say its worth it in the end lol .
