Raspberry Cane Pruning
It seems very odd that you do not have any new canes, usually these are easily identified because the canes that have fruited this year should be starting to die off. I’m just wondering if you have got autumn fruiting raspberries opposed to a summer fruiting variety, the fact that you had raspberries until October suggests that this may be the case.
Autumn fruiting raspberries are pruned differently to summer varieties. The canes should be cut down to ground level in February, they will then start to grow back over the Spring for a late summer harvest.
If you decide that you do have summer raspberries then the following applies:
Cut back fruited canes to ground level after harvesting (do not leave old stubs)
Select the strongest young canes, around six to eight per plant, and tie them in 8 –10cm (3–4in) apart along the wire supports.
Remove the remaining young stems to ground level to avoid overcrowding.
I hope this helps!
