Transplanting Butterfly Bush pt . 2

Hi Marianne,

Thank you so much for answering our questions. I really appreciate it.
So here’s another for you.

Earlier this year I asked about transplanting a butterfly bush that was too big for the space. Now that I’m digging it out I find that the root system is way bigger–as in the roots are large around and very long. I have had to cut them to get the plant out.
My question is: Can I leave the rest of the roots in the ground –actually only one long one that is seemingly growing under my barberry bush. I was able to get the other long thick ones out after cutting from the bush. Will it just die off?
I don’t want the bush to grow back again!

Thanks!
Suzette B
