Here is my privet.
Last year I started a "layer" in a deep pot to reduce the height of this tree. I left it until now. The results were far less spectacular that I had hoped. The layer produced only 3 small roots, so I don't know if this tree is going to make it.
The bottom of the tree however has produced an insane amount of roots.Rather than throwing the bottom away I decided to try my hand at root cuttings. Here they are in a pot. Maybe some day a group planting....
