Photo below shows berries (very tasty, larger than any rasps I've had before, so not sure what they are, wrong shape for tayberries.
Problem is the leaves - a lot of them have yellow blotches on them, they're all mottled - no beasties. What's the cause do you think? Is it the variable weather or should I have a closer look for beasties?
Fruit is absolutely delicious by the way.
