Thanks for the comments, guys.
I do plan on thinning the patches this fall. I'm going to mark the areas tha need to be transplanted.... And begin this august, early sept. I hope to transplant quite a few from patch two, as that patch - from top to bottom- is very thick.
Having said that, there is at least a 20% loss of plants over last year. I understand why some people plant heavy... If I have another 20% loss in there! I'm not likely to transplant too much from it. I do have some areas in patch one that are thick as well, so am going to start there. I am planning on using a flower bulb tool to remove the plant. This bulb tool will allow me to get that plant/root all at once, and the surrounding soil as well. Should simplify things a bit that way.
