Thornless blackberry pruning help!

[HaveYouSeenHerLately]

I planted a thornless blackberry bush from Aldi at least 2yrs ago (maybe 3?).

It's in a moderately sunny position with lots of support (old wire link fence) and fairly decent soil.

I haven't had a great deal of fruit yet, can anyone advise? I can't remember the variety, it was a 2nd year fruiting one. I've never pruned it - it only formed decent canes last year. Should I have pruned them back in autumn? It only has two or three canes so I'm hesitant to chop them back

You cut back the canes that have previously fruited in the autumn and then the younger canes produce fruit over the summer. New canes (for the following year's fruit) start growing in the spring.

Thanks Gin!

It feels counterintuitive as they've not fruited much thus far but that's no doubt why

I'm wondering if I can get away with pruning now as I missed the autumn window?

Better to do it now than not to do it I reckon!

Right, a job for tomorrow! Thanks guys
