Congratulations on a new sprout!
I live in Pittsburgh (US) where these plants are
native and grow wild. As a food resource these patches must be maintained and taken care of to keep up production.
Unmanaged berry patches turn into thick thorny patches that are very difficult to manage or maintain, that will need cut to ground level to be properly set-up.
These are highly invasive plants, and can easily take over forests, any disturbed soil and turn them into unmanageable thorn beds.
With all that being said, these are my favorite types of fruit, and they are a wonderful addition to any garden or maintained environment.
I have a wild black raspberries patch that established in my parent's back
yard that I started tending recently.
I'll be happy to mail some seeds to you if they actually produce good fruit.
Good luck getting your berry patch set-up!
