Shadegardener and SunnyBorders - Thank you for the advice. I have fearlessly chopped up "some" perennials and moved them fearlessly, but have hesitated with the Jack Frpst Brunerra, as it was my only one.
But looking at it carefully, it seems to be in 3 individual parts now. So I have going to take my sharp spade and take 2 parts out now carefully and replant them in the most similar situations I can see in improved soil'
Thank you for the advice. I was very uncertain about disturbing the Brunerra. I have coddled that baby for a decade but I agree it can be divided.
And if it doesn't work, I won't blame you. *I* am making the decision.
