I have two half sized allotments. My first one had over grown raspberries . I weeded them and watched them but after three years I gave up and dug them up as I was getting very small berries and not many. My second half allotment I took over last September with over grown raspberries, but this time they look nice and taste good.So I cut them down a few months ago .( I think they must be autumn fruiting) Like yours they are full of couch grass. I plan to try to weed them but the weather has been so wet I have not been able to do much. I will give them one season then start again if no improvement. It seems a shame not to try. I have no real knowledge so am not saying try to keep them I just thought it might help to know you are not alone.
