>>> New shoots come up from the roots. <<<
Thanks for the heads-up on that!
I’ll handle it like one of the mint family. Stick a chimney tile in the ground and plant inside that.
The roots will probably break it.
It’s not a small bush it’s a small tree.
Left alone you will have multiple offshoots coming up that will get over 6 inches in diameter and over 15 feet high.
