This is how raspberries work. They are either primocane or floricane, which describes how they fruit. If they fruit on last years growth, I think, it’s prune (in winter) the canes which fruited the season just gone as they won’t fruit again.
Oh, no I mean the ones that should be fruiting now just don't really grow well because of dry soil in the summer, whereas the ones that grew last year and fruit earlier when it's damp do much better, so hoped that an irrigation system might get them both growing well
