Just to get some more information - It looks like you planted it in a large pot? What climate are you in?
I’m in Florida, so zone 9 & 10, I also have a florida thornless variety of blackberry - so they are fairly hardy.
I didn’t post a very good pic before - my concern is the green stem is going brown and the leaves are going brittle and brown as well.
As a note the blackberry has only been in the pot for about 2 weeks.
