Well she finally got rootbound and was repelling water so I had to take drastic measures - she needed a transplant!
This is how it looked when I started:
It looks like one plant but it is really two - the flower clone is in a container that is obscured by the bush:
When I nudged up the container there were no audible rips of roots and when I got her on her side there were only a few minor roots poking through the holes!
The container was very rootbound and came out cleanly:
With the help of some poles and curbs she is in place and well watered!
Whew!
Cheers,
Mo
