Raspberries fall into two main categories; those that fruit in the summer and those that fruit later on into autumn. They are treated very differently with regards to pruning.
Summer raspberries
These will have finished fruiting now and it should be easy to distinguish the old canes from the new ones. All the fruited canes will start to die and can be pruned right down to the ground. The new ones will have been getting in your way while picking the fruit and can now be tied in to their support. I usually cut the tops off to a sensible height but you can bend them over if space allows. Any that are weak, overcrowding or just coming up in a silly place should be removed.
Autumn raspberries
If you get it right, the autumn type should begin to fruit as the summer ones finish! They continue until the frosts set in which can be up to Christmas. They do not generally need tying in to a support as they are not as tall as the summer ones but it may be helpful for ease of picking. Pruning involves cutting all the fruited canes to the ground in February after which time new canes will emerge from the ground for fruiting later on that season and off we go again…
Potash
Raspberries need their potash in the same way as tomatoes to encourage fruiting. Ash from the wood burning stove is an excellent source and can be applied directly or put into the compost bin for later use.
