I'd agree, raspberries are pretty indestructable. We planted 20 canes two years ago and had 20lbs of fruit the first year, last year there was so much I even exhausted my list of people who normally happily take all my surplus. I still have about 15lbs in the freezer, which need to be used to make room for this years glut....er.....crop. In my experience they certainly don't need any extra help or consideration in getting themselves established.
