Seperating newly rooted raspberry shoots
I have a 1-2 yo raspberry bush near a fence.
It gave beautiful and yummy fruit last year but I didn't prune it afterwards (didn't know I should have).
Now some of it's shoots are a few meters long and some of them went back into the ground and rooted there quite deeply.
I know that a new bush will grow from that point but I don't know if I should cut the cord between the mother bush and the new one, when to do it, and where to to it.
