Im guessing the suckering will take place once the roots establish more… i read something like after the first few years… and then a person would have to not mow or at least be wary of suckers.
I think ripening times are different for different climates… some reports are August while others are July… so for me here its about the same time that the wineberries and wild blackberries ripen which was about 2 weeks ago.
FYI you can probably speed up the process by root cuttings or spading around the plants with a shovel… etc etc… just saying.
