Well you could but….
I wouldn’t!
because:
in my case ground is limited for cultivation and priorities exceed blackberries. There are many acres of ‘wild’ blackberry brambles within a mile.
If giving up growing space and having the need to contain/protect/nurture/harvest I would be tempted to grow a cultivated hybrid or two for better fruit.
Your neighbours will think your letting it ‘go to rack ‘n ruin’; and probably not resist’just pickin a few’ole berries…
