This is my Kiyohime Maple.
When I bought this tree it’s trunk was only pencil thin.
So the tree has unrestricted growth for the past mmmmmm maybe 8 to 10 years.
So now i’m happy with the trunk and overall size of the tree.
Now the root ball has been cut back by about 60% to 70%
This is the tree now ready for it’s new pot, I will post a few photes of the tree potted up shortly,,,,my camera ran out of battery Grrrrr.

Hi Bonsai Baker. Its interesting to see you repotting as early as this. Looks good
A littil winter protection is needed this early.
Nice broom style tree in the making? What colour are the leaves?
The leaves are mostly green over the summer, a little colour at the end of the year, but it’s the small leaf size that makes Kiyohime intresting. Peter always has a few, when he is next over,have a look Ben.
