Blackberries need pruning and support

Just a little video talking about these blackberries they are thornless southern blackberries. I’m growing them in zone AA I ordered them from Baker Creek heirloom seeds in 2018 and I’ve been slowly spreading them out since then I love them but they do need some pruning and some maintenance. I don’t actually water these here in zone eight they are too far from the house from my hose to reach and I just rely on nice spring rains is going well so far this year but on a drought year, I might have to water them
