Thanks Guys,
Adam, I haven't measured it it bo honest. I try that later. It isn't a tall tree. I was lucky to find it. A;; I could see was a little foliage poking out of some heather. It was collected three years ago. I don't repot until the foliage is that lush colour.
Barry,
You are not off base at all. When I was taking the photos between washing out the old soil I was looking for ideas in the tree. I hadn't seen the other side in three years and was amazed by what I'd missed. Your cascade idea was one of the options I saw although it was more a semi cascade. I saw loads of options in fact. Nearly all from the other side that had been hidden from me. Once we got it potted up we spun it around some looking for more. The whole repotting from start to finish took 3 1/2 hours.
Regards
Ian
