What will Autumn fruiting raspberries do if you just leave the fruited canes untouched?

I always recall talking to someone at a nursery who said Summer and Autumn ones are the same.
The grow a cane, produce flowers then fruit then you cut them down.
The difference was that one had Winter in the middle of the process but that was our way of judging time, more specifically this year and last year. But the summer ones produced fruit on what was to them this years growth - as in growth produced during the last period of one year, not growth before and after Jan 1st.

Just eat raspberries when they're there and cut them down when they look really really dead - thats what I do

I can tie in my unfruited canes as the season here can be very late in starting, so at the moment I have 23 canes from last year, joan j and polka autumn canes, as last year spring did not start until into June, so it was too late for all to fruit , even if we did pick into December, I just trim them to about 5/6ft, and tie them in before the winter storms, we are still using those we froze down as when they did produce they really did go mega...magic, as with cooler weather, they ripen slower, but the taste is superb, so much better than the shop bought stuff..

Autumn Rasps fruit on the current years growth whereas Summer Rasps fruit on the previous years growth. If you were to cut last years Summer canes out, you would get no crop this year.

I treat my Autumn Bliss raspberries like that.

You'll probably have a dead bit on the top, that has flowered but new fruiting bits will come from the side of the canes. (I'm trying not to make this too technical!).
My rule is - if its dead, off with its head, if its alive, let it thrive.

That's far too easy..............growing Raspberries is not supposed to be easy.
