The raspberries are struggling on. Out of the 7 planted 3 are still sprouting new leaves, one even has a flower bud on it. The other 4 (3 of which were planted in full sun) are leafless. I'm not giving up on them yet as one started to sprout from the ground a while ago.
In contrast, our raspberries at home are giving us about a kilo a week. They were planted about 3 years ago and are in part sun part shade. I seem to remember they struggled in their first year too.
