First, weather permitting, dig up and move away from your neighbor's reach what was left. This will sprout and start growing. Brugs usually grow fast. Then if you have what they cut off, put in water to root and then plant either in the ground or pot so you can have other plants.

Thank you. I will try all this. Hope it will sprout.(my big concern is that I do not see active "eyes").

They can still sprout from below the ground.
