Here are a couple of pictures. I realize you can't really see the ends well but there are small roots on the ends where they were ripped out of the ground. And yes, she pulled (ripped, thrashed, broke) the new canes out of the ground, you can see them in the pictures. Every. New. Cane.
Why go into someones garden anyway? Well, I found out she was picking the berries....

and thought she would weed to compensate for her berry picking. Needles to say, bad choice, bad decision.
The blackberry bushes I grow are thornless and the old canes, with the green berries, on them seem to be doing ok but the bushes are really loose in the ground....
Thank you all for your input! Ill just have to wait, one day at a time.
