In my yard, in Washington State, my dear sweet late neighbor, Grammpa Neighbor, as the kids called him, planted mint. Just a little tiny bit, next to his basil, he wanted to make Mojitos. He was a loving and special gentleman, and I just could not tell him his mint was going to spread to both are gardens in a way we would curse later. And in a season or two, we saw alot of each other, as his mint patch had become a weedy nightmare.
He passed 15 or more years ago, but that stinking mint is going to outlive us all, and choke out anything in it's path.
Is there any other plant you have too many of, you could do a test run on, so as not to harm such a big and beautiful tree.
Good luck, with it. It sure will be pretty if it does no harm in a pot.
Good Luck
