@jabel they’ll flower on growth at least a year old and tend to be very productive for fruit. They also self-seed. Great for birds. If you are thinking about human consumption, maybe prune short and perhaps let a new stem grow each year and prune out older ones (I’m guessing as I use mine as a screen above the 6-foot fence line). They will tend to regrow at the prune cut too. Lots of options lol
