How and when to prune raspberries

I have Autumn fruiting raspberry plants when should they stop producing fruit and then how do I go about pruning them.I know summer ones are normally cut down to about five inches from the ground is it the same with autumn one's.They are now starting to produce fruit.

 

I'll be a bit controversial again here.
I do something a little different to the books and do a half and half with the late fruiting ones, half the canes are cut to the ground to encourage new growth for the following late season. The other half I treat like earlier fruiters and cut to about a foot or two, this gives an earlier crop of fruit, all be it the early ones are not quite as tasty. Of course if you have room to grow both varieties, then there's no need for this approach. I did this for about ten years and the canes seemed to be fine with this treatment.

 

I have a dwarf patio raspberry I bought this year so no fruit this year. Would I need to prune it in its first year? If so, when and by how much? Also, when would I expect to see my first fruit - 2nd year?

 

Do you know if the is a early or late fruiting variety? Not familiar with dwarf patio types to be honest.

 

I think it's a Ruby Beauty, which produces fruit in the summer

 

Summer fruiting varieties are pruned by removing the wood that had fruit on this year right down to the ground. Tie in the new shoots with no fruit as they will give you next years crop. Autumn fruiting varieties are pruned down to the ground in late winter and the fruit will be on the new growth in the same year. Both like high potash fertilizer, my dad used to used ashes from a wood firs he kept in a small heap at the bottom of the garden. Glen Clova and Glen Prosen(both Glens in the Angus hills near me) are two good early/mid season growers, I'm replacing mine later this year, I've no room for autumn fruiting varieties now.

 

As I only purchased my raspberry this year and has produced no fruit, do I still need to prune it?

 

Sounds like it is the type that fruit on last years wood, I would support the canes so the winter winds don't damage them or loosen the roots and see what you get next year. So no don't prune it, you only take out the wood that has produced this year.
