I am familiar with cutting to the ground after this year's harvest for the blackberries as well as the summer harvest for the raspberries, but my questions are:
Blackberries:
This years new growth that will produce fruit next year, do you prune these back in the fall? If so how much do you typically cut back? I have some new growth that started this spring and is already 10-11ft tall.

Everbearing Raspberries:
The new growth this year that will produce in the fall, what do you do after the harvest is over?

Thanks in advance
