There's a good chance that having pulled whatever it is up, you have terminated its existence! Don't be too hopeful about it re-growing.
I said those very words to my 13year old grandson, or very much like
He's really keen on veg growing but this year his beetroots and carrots took so long to germinate they got weedy. So what did he do, he dug them up, sorted them out and replanted the baby beetroot and carrots. I told him they would die, what a rotten nana :DBut what are they doing , they're growing lovely.
Hope your thingy does the same jules n tony
