I am also doing very well on raspberries this year, though they are wanting some rain now.
I do not think there is such a thing as too many raspberries. I just love them.
I had a gap between the summer and autumn ones and I am working hard to fill.
The autumn ones are fantastic. They are more tolerant of the lime in the soil. I have JoanJ and they are spreading all over the place, but I do not mind. They produce for weeks and weeks so well worth growing. They are bigger fruits than the summer ones though not quite as good on flavour but I still love them. I do recommend. The birds do not seem to go for them as much as the summer ones.
