Looks like she is coming along nicely. Good job

Question... How do I keep her alive for a couple of years as a mother plant? We have taken clones from her and they are extremely vigorous and doing quite well. She is about 9 feet tall her branches are heavily flowered on the ends of the branches. There are flowers all along the branch except for maybe the first several inches. I was wondering, how do I harvest with butchering her so she doesn't go into shock and die? Any and all suggestions are appreciated.
