Just Planted Boysenberry Plants

Question

They are about 3-4 feet tall. Should I prune them a bit after the transplant?

Not now. Wait until late summer, or even better, near dormancy.

I note that there doesn't seem to be any drainage holes drilled. This will end up being what kills those plants. There need to be plenty of drainage holes on the sides, and bottom of the container to allow all extra water to leave the bucket, immediately, when watering. They appear to be quite overwatered.

Here are two articles that will help:
