My Raspberry And Blackberry Bush Leaves Are Curling

Question

We live in Colorado where we may get torrential rain in the afternoons and our soil is clay. We tried digging up large holes and filling with good garden soil replanted the berries last year because we told by our local nursery that the issue may be too much water with poor drainage. I just want to confirm that this is indeed the issue because while the plants looked so healthy last month, the leaves are starting to curl again.

This, certainly, looks to be the issue. This damage will indicate a soil drainage, or overatering issue.
